General Information Operator’s Manual The Operator’s Manual provides information regarding the operation, general maintenance and maintenance intervals for your Reelmaster machine. Refer to that publication for additional information when servicing the machine. Towing Traction Unit IMPORTANT: If towing limits are exceeded, severe damage to the piston pump may occur. 1 If it becomes necessary to tow (or push) the machine, tow (or push) in a forward direction only, at a speed below 3 mph (4.
Relieving Hydraulic System Pressure Before disconnecting or performing any work on the hydraulic system, all pressure in the hydraulic system must be relieved. Park machine on a level surface, lower cutting units fully, stop engine and apply parking brake. To relieve hydraulic pressure in traction circuit, move traction pedal to both forward and reverse directions. To relieve hydraulic pressure in steering circuit, rotate steering wheel in both directions.
Hydraulic Hoses Hydraulic hoses are subject to extreme conditions such as pressure differentials during operation and exposure to weather, sun, chemicals, very warm storage conditions or mishandling during operation and maintenance. These conditions can cause hose damage and deterioration. Some hoses are more susceptible to these conditions than others.
Hydraulic Hose and Tube Installation (O--Ring Face Seal Fitting) 1. Make sure threads and sealing surfaces of the hose/ tube and the fitting are free of burrs, nicks, scratches or any foreign material. C. Use a second wrench to tighten the nut to the correct Flats From Wrench Resistance (F.F.W.R.). The markings on the nut and fitting body will verify that the connection has been properly tightened. 2.
Hydraulic Fitting Installation (SAE Straight Thread O--Ring Fitting into Component Port) Non--Adjustable Fitting (Fig. 6) 1. Make sure all threads and sealing surfaces of fitting and component port are free of burrs, nicks, scratches or any foreign material. 5. If a torque wrench is not available, or if space at the port prevents use of a torque wrench, an alternate method of assembly is the Flats From Finger Tight (F.F.F.T.) method. 2.
Adjustable Fitting (Fig. 8) 1. Make sure all threads and sealing surfaces of fitting and component port are free of burrs, nicks, scratches or any foreign material. 2. As a preventative measure against leakage, it is recommended that the O--ring be replaced any time the connection is opened. Lock Nut 3. Lightly lubricate the O--ring with clean hydraulic oil. Fitting threads should be clean with no lubricant applied. Back--up Washer 4. Turn back the lock nut as far as possible.

Traction Circuit: Mow Speed (4WD) The traction circuit piston pump is a variable displacement pump that is directly coupled to the engine flywheel. Pushing the traction pedal engages a hydraulic servo valve which controls the variable displacement piston pump swash plate to create a flow of oil. This oil is directed to the front wheel and rear axle motors.

Traction Circuit: Transport Speed (2WD) Traction circuit pressure (forward and reverse) can be measured at test ports located on the traction circuit hydraulic tubes of the machine. The traction circuit pump and motors use a small amount of hydraulic fluid for internal lubrication. Fluid is designed to leak across traction pump and motor components into the case drain. This leakage results in the loss of hydraulic fluid from the closed loop traction circuit that must be replaced.

Engine Cooling Fan Circuit The fan control manifold controls the operation of the hydraulic motor that drives the engine cooling fan in addition to including the flow divider (FD) for the steering and lift circuits. The electronically controlled proportional relief valve (PRV) in the manifold controls the oil flow to the fan motor. The fan control manifold controls the speed and direction of the fan motor based on electrical output from the TEC controller.
Special Tools Order the following special tools from your Toro Distributor. Hydraulic Pressure Test Kit Use to take various pressure readings for diagnostic tests. Quick disconnect fittings provided attach directly to mating fittings on machine test ports without tools. A high pressure hose is provided for remote readings. Contains one each: 1000 PSI (70 Bar), 5000 PSI (350 Bar) and 10000 PSI (700 Bar) gauges. Use gauges as recommended in Testing section of this chapter.
40 GPM Hydraulic Tester (Pressure and Flow) Use to test hydraulic circuits and components for flow and pressure capacities as recommended in the Testing section of this chapter. This tester includes the following: 1. LOAD VALVE: A simulated working load is created in the circuit by turning the valve to restrict flow. 2. PRESSURE GAUGE: Glycerine filled 0 to 5000 PSI gauge to provide operating circuit pressure. 3.
High Flow Hydraulic Filter Kit The high flow hydraulic filter kit is designed with large flow (40 GPM/150 LPM) and high pressure (5000 PSI/345 bar) capabilities. This kit provides for bi--directional filtration which prevents filtered debris from being allowed back into the circuit regardless of flow direction. If a component failure occurs in the closed loop traction circuit, contamination from the failed part will remain in the circuit until removed.
Measuring Container Use this container for doing hydraulic motor efficiency testing (motors with case drain lines only). Measure efficiency of a hydraulic motor by restricting the outlet flow from the motor and measuring leakage from the case drain line while the motor is pressurized by the hydraulic system.

Troubleshooting The charts that follow contain information to assist in hydraulic system troubleshooting. There may possibly be more than one cause for a machine malfunction. Refer to the Testing section of this Chapter for precautions and specific testing procedures. General Hydraulic System Problems Problem Possible Cause Hydraulic system operates hot. Engine RPM is too low.
Traction Circuit Problems NOTE: When troubleshooting traction circuit problems, if a problem exists in both mow speed (4WD) and transport speed (2WD), consider a faulty component that affects the entire traction circuit (e.g. charge circuit, relief valves, piston pump, front wheel motors). If the problem exists in mow speed (4WD) but not in transport speed (2WD), consider a problem in the 4WD traction system (e.g. rear axle motor, cartridge valves in 4WD/2WD control manifold).
PTO Problems Problem Possible Cause None of the cutting units will operate. Cutting units are not fully lowered to ground. NOTE: Cutting units have to be fully lowered and traction speed needs to be in mow speed (4WD) for cutting units to operate. Operator seat is unoccupied. Mow speed limiter is in transport (2WD) position. Electrical problem exists that prevents mow control manifold solenoid valve operation (see Chapter 5 -- Electrical System). Gear pump sections P1 and P2 are damaged.
PTO Problems (Continued) Problem Possible Cause All cutting units operate slowly. Engine RPM is low. Cutting unit motor is damaged. Gear pump section (P1 or P2) is worn or damaged. Cutting unit stops under load. Relief valve in mow control manifold is bypassing. Cutting conditions (e.g. very tall or wet grass) exceed cutting unit capacity. Cutting unit motor relief valve is stuck or damaged. Gear pump section (P1 or P2) for affected cutting units is worn or damaged.
Lift/Lower Circuit Problems Problem Possible Cause Cutting units will not raise. Operator seat is unoccupied. NOTE: Operator must be in seat in order to raise the cutting units. Hydraulic oil level in reservoir is low. Electrical problem exists that prevents lift control manifold solenoid valve operation (see Chapter 5 -- Electrical System). Lift cylinder(s) is (are) damaged. Lift arm pivots are binding. Lift/lower circuit relief valve (RV1) in lift control manifold is stuck open.
Engine Cooling Fan Circuit Problems Problem Possible Cause Cooling fan runs only in forward direction (fan does not run in reverse direction). Fan control manifold solenoid cartridge valve (S1) is faulty. Cooling fan does not rotate. Fan motor is worn or damaged. Electrical problem exists that prevents fan control manifold solenoid valve (S1) operation (see Chapter 5 -- Electrical System). Gear pump section (P4) is worn or damaged. Cooling fan always rotates at slow speed.
Testing The most effective method for isolating problems in the hydraulic system is by using hydraulic test equipment such as pressure gauges and flow meters in the circuits during various operational checks (See the Special Tools section in this chapter). IMPORTANT: All obvious areas such as oil supply, filter, binding linkages, loose fasteners or improper adjustments must be checked before assuming that a hydraulic component is the source of the problem.
Which Hydraulic Tests Are Necessary? Before beginning any hydraulic test, identify if the problem is related to the traction circuit, mow circuit, lift/lower circuit, steering circuit or engine cooling fan circuit. Once the faulty system has been identified, perform tests that relate to that circuit. 1.

Service and Repairs General Precautions for Removing and Installing Hydraulic System Components Before Repair or Replacement of Hydraulic Components After Repair or Replacement of Hydraulic Components 1. Before removing any parts from the hydraulic system, park machine on a level surface, engage parking brake, lower cutting units or attachments and stop engine. Remove key from the ignition switch. 1. Check oil level in the hydraulic reservoir and add correct oil if necessary.
Check Hydraulic Lines and Hoses IMPORTANT: Check hydraulic lines and hoses daily for leaks, kinked lines, loose mounting supports, wear, loose fittings or deterioration. Make all necessary repairs before operating the machine. WARNING Keep body and hands away from pin hole leaks or nozzles that eject hydraulic fluid under high pressure. Use paper or cardboard, not hands, to search for leaks. Hydraulic fluid escaping under pressure can have sufficient force to penetrate the skin and cause serious injury.
Flush Hydraulic System IMPORTANT: Flush the hydraulic system any time there is a severe component failure or the system is contaminated (oil appears milky, black or contains metal particles). IMPORTANT: Flush hydraulic system when changIng from petroleum base hydraulic fluid to a biodegradable fluid. Operate machine under normal operating conditions for at least four (4) hours before draining. 1. Park machine on a level surface. Lower cutting units, stop engine and engage parking brake.
Filtering Closed--Loop Traction Circuit Filtering of a closed--loop hydraulic system after a major component failure (e.g. traction (piston) pump or front wheel motor) is a requirement to prevent debris from transmitting throughout the system. If a closed--loop hydraulic system filtering tool is not used to ensure system cleanliness, repeat failures, as well as subsequent damage to other hydraulic components in the affected system, will occur.
Charge Hydraulic System IMPORTANT: Change hydraulic oil filter whenever hydraulic components are repaired or replaced. 11. After the hydraulic system starts to show signs of fill, actuate lift control switch until the lift cylinder rods move in and out several times. If the cylinder rods do not move after fifteen (15) seconds or the pump emits abnormal sounds, shut the engine off immediately and determine cause or problem. Inspect for the following: A. Loose filter or suction lines. 1.

General Information Operator’s Manual The Operator’s Manual provides information regarding the operation, general maintenance and maintenance intervals for your Reelmaster machine. Refer to the Operator’s Manual for additional information when servicing the machine. Toro Electronic Controller (TEC) Reelmaster 7000 machines use a single Toro Electronic Controller (TEC) to manage machine electrical functions.
Electrical Drawings Electrical System The electrical schematics and other electrical drawings for the Reelmaster 7000 are located in Chapter 9 -- Foldout Drawings.
Special Tools Order special tools from your Toro distributor. Some tools may also be available from a local supplier. Multimeter The multimeter can test electrical components and circuits for current (amps), resistance (ohms) or voltage. Obtain this tool locally. NOTE: Toro recommends the use of a DIGITAL VoltOhm- Amp multimeter when testing electrical circuits.
Diagnostic Display The Diagnostic Display (Fig. 5) can be connected to the wiring harness connector located inside the console arm to verify correct electrical functions of the machine. Toro Electronic Controllers (TEC) inputs and outputs can be checked using the Diagnostic Display. Toro Part Number for Diagnostic Display: 85- 4750 Toro Part Number for Overlay (English): 120- 1679 NOTE: Diagnostic Display overlays are available in several languages for your Reelmaster.
Troubleshooting For effective troubleshooting and repairs, there must be a good understanding of the electrical circuits and components used on this machine (see Chapter 9 -- Foldout Drawings). CAUTION Remove all jewelry, especially rings and watches, before doing any electrical troubleshooting or testing. Disconnect the battery cables unless the test requires battery voltage. If the machine has any interlock switches by--passed, reconnect the switches for proper safety and troubleshooting.
5. The “inputs displayed” LED, on lower right column of the Diagnostic Display, should be illuminated. If “outputs displayed” LED is illuminated, press the toggle button on the Diagnostic Display to change to “inputs displayed” LED. TEC OVERLAY 6. The Diagnostic Display will illuminate the LED associated with each of the inputs when that input switch is closed.

Ground connection on machine is loose or corroded. Fuse F3--1 (2 amp) is faulty (open). The ignition switch or circuit wiring is faulty. Starter solenoid clicks, but starter will not crank. Battery is discharged. NOTE: If the solenoid clicks, the problem is not in the in- Battery cables are loose or corroded. terlock circuit.
Starting Problems (continued) Problem Possible Causes Engine cranks, but does not start. Fuel tank is empty. Engine is not cranking fast enough. Engine and/or fuel may be too cold. Fuse F5--1 (40 amp) is faulty (open). Glow relay, glow plugs or fuse M1 (60 amp) are faulty. Engine run solenoid or circuit wiring is faulty. Fuel pump is faulty. Engine or fuel system is malfunctioning (see Chapter 3 -- Kubota Diesel Engine). Starter cranks, but should not when the traction pedal is depressed.
Cutting Unit Operating Problems Cutting units run, but should not, when raised. Cutting units shut off with PTO switch. The cutting unit position switch or circuit wiring is faulty. Wire harness connections are incorrectly connected to hydraulic solenoid valve coils on hydraulic mow control manifold. Cutting units run, but should not, when raised. Cutting units do not shut off with the PTO switch. The cutting unit position switch or circuit wiring AND PTO switch or circuit wiring are faulty.
Electrical System Quick Checks Battery Test (Open Circuit Test) Use a multimeter to measure the voltage between the battery terminals. Voltage Measured Battery Charge Level 12.68 V (or higher) Fully charged (100%) Set multimeter to the DC volts setting. The battery should be at a temperature of 60o to 100oF (16o to 38oC). The ignition key should be off and all accessories turned off.
Check Operation of Interlock Switches CAUTION Do not disconnect safety switches. They are for the operator’s protection. Check the operation of the interlock switches daily for proper operation. Replace any malfunctioning switches before operating the machine. Electrical System Interlock switch operation is described in the Traction Unit Operator’s Manual. Your Reelmaster is equipped with an Toro Electronic Controller (TEC) which monitors interlock switch operation.
Adjustments Mow/Transport Sensor The mow/transport sensor is a normally open proximity sensor that closes when the mow speed limiter is placed in the transport position. The sensor mounts to a bracket on the footrest platform (Fig. 12). The sensing plate for the mow/transport sensor is a tab on the mow speed limiter. 2 Adjustment 1. The gap between the mow/transport sensor and the mow speed limiter should be from 0.040” to 0.100” (1.1 to 2.5 mm). 2.
Cutting Unit Position Sensor The cutting unit position sensor is a normally open proximity sensor that is located on the front carrier frame (Fig. 13). The sensing plate that closes the sensor is a gusset on the front right cutting unit (#5) lift arm. When the cutting units are lowered, the gusset on the lift arm is located near the position sensor and the sensor closes. This closed sensor provides an input for the TEC controller to allow the lowered cutting units to operate.
Component Testing For accurate resistance and/or continuity checks, electrically disconnect the component being tested from the circuit (e.g. unplug the ignition switch connector before checking continuity on the switch terminals). NOTE: For engine component testing information, see the Kubota Workshop Manual, Diesel Engine, 03--M-DI--E3B. CAUTION When testing electrical components for continuity with a multimeter (ohms setting), make sure that power to the circuit has been disconnected.
Fuses Your Reelmaster 7000 uses numerous fuses for circuit protection. The fuses are located in two (2) areas of the machine. Most of the fuses reside in the power center behind the operator’s seat. An in--line fuse holder located in the wire harness near the engine starter motor holds an additional fuse (F5--1) that protects the engine run solenoid pull coil circuit. Fuse Testing Fuse Identification and Function (Figs. 17 and 18) 3. Remove fuse from fuse block for testing.
Indicator Lights Charge Indicator Light The charge indicator light should come on when the ignition switch is in ON with the engine not running or with an improperly operating charging circuit while the engine is running. 3 2 4 To test the charge indicator light and circuit wiring, ground the white wire attached to alternator. Turn ignition switch to ON; the charge indicator light should illuminate indicating correct operation of the electrical wiring to the alternator.
Hour Meter The hour meter is located on the outside of the console arm. Hobbs 1. Connect the positive (+) terminal of a 12 VDC source to the positive (+) terminal of the hour meter. QUARTZ 00001 HOURS 2. Connect the negative (--) terminal of the voltage source to the other terminal of the hour meter. 1 10 + 3. The hour meter should move a 1/10 of an hour in six (6) minutes. 4. Disconnect voltage source from the hour meter.
PTO Switch The PTO switch is located on the console arm (Fig. 23). The PTO switch is pulled up to engage the PTO and pushed in to disengage the PTO. NOTE: To engage the PTO, the seat has to be occupied, traction speed has to be in low range (4WD) and the cutting units have to be fully lowered. 7. After testing is completed, connect the wire harness connector to the PTO switch. 8. Assemble console arm (see Console Arm Assembly in the Service and Repairs section of Chapter 7 -- Chassis). Testing 1.
Cutting Unit Lift Switch The cutting unit lift switch is used as an input for the TEC controller to raise or lower the cutting units. When the lift switch paddle is depressed and held, the cutting units will lower. When the lift switch paddle is raised and held, the cutting units will raise. The cutting units will remain in position when the switch is released. The lift switch is located on the console arm (Fig. 25). 7. After testing is completed, connect wire harness connector to the lift switch. 8.
Headlight Switch The headlight switch is located on the operator side of the console arm (Fig. 28). This two (2) position rocker switch allows the headlights to be turned on and off. 1 Testing 1. Make sure ignition switch is OFF. Remove key from ignition switch. 2. Disassemble console arm to gain access to headlight switch (see Console Arm Disassembly in the Service and Repairs section of Chapter 7 -- Chassis). 3. Disconnect harness electrical connector from the switch.
Engine Cooling Fan Switch The engine cooling fan switch is located on the outside of the console arm (Fig. 30). This two (2) position rocker switch allows the engine cooling fan to run in the normal, automatic mode or in the manual reverse (momentary) direction. 2 Testing 1. Before disconnecting the engine cooling fan switch for testing, the switch and its circuit wiring should be tested as a TEC input with the Diagnostic Display (see Diagnostic Display in the Troubleshooting section of this chapter).
Seat Switch The seat switch is normally open and closes when the operator is on the seat. The seat switch and its electrical connector are located in the seat assembly. If the traction system or PTO switch is engaged when the operator raises out of the seat, the engine will stop. Testing of the switch can be done without seat removal by disconnecting the switch wire from the machine wire harness (Fig. 32). Testing 1.
Parking Brake Switch The parking brake switch is a normally open proximity switch. The parking brake switch is attached to the bottom of the RH brake pedal (Fig. 33). When the parking brake is not applied, the parking brake detent is positioned near the target end of the parking brake switch so the switch is closed. The parking brake detent is moved away from the switch when the parking brake is applied causing the switch to open. Switch Testing 1.
Mow/Transport Sensor The mow/transport sensor is a normally open proximity sensor that closes when the mow speed limiter is placed in the transport (2WD) position. The sensor mounts to a bracket on the footrest platform. The sensing plate for the mow/transport sensor is the mow speed limiter. The mow/transport sensor is used as an input for the TEC controller. 4.
Cutting Unit Position Sensor The cutting unit position sensor is a normally open proximity sensor that is located on the traction unit frame (Fig. 36). The sensing plate that closes the sensor is a gusset on the front right cutting unit (#5) lift arm. 5. If the cutting unit position sensor tests correctly and a circuit problem still exists, check wire harness (see Electrical Schematic and Wire Harness Drawings in Chapter 9 -- Foldout Drawings).
Backlap Switches The backlap switches are normally open ball switches that are in the normal, open state when the backlap levers are in the mow position. When a backlap lever is in the backlap position, the switch closes. The backlap switches are attached to the hydraulic mow control manifold located under the hood (Fig. 38). The Toro Electronic Controller (TEC) uses the backlap switches as inputs. 1 2 4 Testing 3 1.
Glow and Main Power Relays The glow and main power relays are located at the power center behind the operator seat (Fig. 40). These relays are attached to the wire harness with a four (4) wire connector (Fig. 41). The glow relay is used to provide current to the engine glow plugs when energized by the TEC controller. The TEC controls and monitors the operation of the glow relay. 7. Disconnect voltage and test leads from the relay terminals. 8.
Start Relay The start relay is located at the power center behind the operator seat (Fig. 42). This relay is attached to the wire harness with a five (5) wire connector (Fig. 43). The start relay is used to provide current to the engine starter motor when energized by the TEC controller. The TEC controls and monitors the operation of the start relay. 10.Secure relay to mounting bracket and connect wire harness connector to relay. Install cover to power center. 11.
Reel Speed Potentiometer The reel speed potentiometer controls the cutting reel speed. The TEC controller uses the potentiometer setting as an input to determine the necessary voltage output for the hydraulic mow control manifold proportional valves (SP1 and SP2) for correct cutting reel speed. The reel speed potentiometer is located under the operator seat (Fig. 44). 1 Testing 1.
Hydraulic Solenoid Valve Coils Numerous hydraulic solenoid valve coils are used on the hydraulic control manifolds of Reelmaster 7000 machines. When energized by the TEC controller, these coils provide hydraulic circuit control. 5. If solenoid coil resistance is incorrect, replace solenoid (see Hydraulic Solenoid Valve Coil Removal and Installation in the Service and Repairs section of this chapter). Two (2) different solenoid valve coils are used on the Reelmaster 7000.
Traction Neutral Switch The traction neutral switch is closed when the traction pedal is in the neutral position and opens when the pedal is depressed in either direction. The switch is located on the right side of the piston (traction) pump (Fig. 47). See Piston Pump Control Assembly in Chapter 4 -- Hydraulic Systems for disassembly and assembly procedures for the neutral switch.
Toro Electronic Controller (TEC) The Reelmaster 7000 uses a Toro Electronic Controller (TEC) to monitor the condition of various switches (inputs) and then directs power output to allow certain machine functions. The controller is located under the operator seat (Fig. 49). The handheld Diagnostic Display (see Special Tools in this chapter) with the correct overlay should be used when checking inputs and outputs of the controller used on your Reelmaster (see Troubleshooting in this chapter).
Engine Coolant and Hydraulic Oil Temperature Senders Two (2) identical temperature senders are used as inputs for the TEC controller to identify if either the engine coolant or hydraulic oil temperature has reached an excessive level. The coolant temperature sender threads into the radiator (Fig. 50). The hydraulic oil temperature sender is attached to the 4WD/2WD control manifold at the front of the machine (Fig. 51). 7. After allowing the sender to cool, install sender: Testing 8.
Fuel Pump The fuel pump is energized by the TEC controller when the ignition switch is either in the START or ON position. The fuel pump is attached to the left side frame rail. 1 3 IMPORTANT: When testing fuel pump, make sure that pump is not operated without fuel. Fuel Pump Capacity Test 1. Park machine on a level surface, lower cutting units, stop engine and engage parking brake. Remove key from ignition switch. 2 2. Raise and support hood. 3. Remove 20A fuse (F1--1) (Fig.
Fuel Stop Solenoid The fuel stop solenoid used on your Reelmaster must be energized for the diesel engine to run. The solenoid is mounted to the injection pump on the engine (Fig. 55). The TEC controller monitors the operation of the fuel stop solenoid. The solenoid and its circuit wiring should be tested as a controller output with the Diagnostic Display before following the testing procedure listed below (see Special Tools and Troubleshooting in this chapter). 1 2 Testing 1.
Engine Temperature Sender The engine temperature sender is located near the alternator on the water flange attached to the engine cylinder head (Fig. 57). There is a gray wire attached to the terminal of the sender. The resistance of the temperature sender reduces as the engine coolant temperature increases. The changing resistance of the temperature sender signals the console temperature gauge to indicate engine coolant temperature during machine operation. Engine Temperature Sender Test 1.
Oil Pressure Switch The engine oil pressure switch is located on the engine above the starter motor (Fig. 59). The oil pressure switch is a normally closed switch that opens with pressure. The oil pressure switch should open at approximately 8 PSI (0.56 kg/cm2). 2 The TEC controller monitors the operation of the oil pressure switch. The switch and its circuit wiring should be tested as a controller input with the Diagnostic Display (see Special Tools and Troubleshooting in this chapter).
Service and Repairs NOTE: For more component repair information, see the Kubota Workshop Manual, Diesel Engine, 03--M-DI--E3B. Battery Storage If the machine will be stored for more than 30 days: 1. Remove the battery and charge it fully (see Battery Service in this section). 2. Either store battery on a shelf or on the machine. 4. Store battery in a cool atmosphere to avoid quick deterioration of the battery charge. 5.
Battery Service The battery is the heart of the electrical system. With regular and proper service, battery life can be extended. Additionally, battery and electrical component failure can be prevented. 1 3 CAUTION 2 When working with batteries, use extreme caution to avoid splashing or spilling electrolyte. Electrolyte can destroy clothing and burn skin or eyes. Always wear safety goggles and a face shield when working with batteries.
Battery Testing C. Make sure battery terminals are free of corrosion. 1. Conduct a hydrometer test of the battery electrolyte. D. Measure the temperature of the center battery cell. A. Measure the specific gravity of each cell with a hydrometer. Draw electrolyte in and out of the hydrometer barrel prior to taking a reading to warm-up the hydrometer. At the same time take the temperature of the cell. B. Temperature correct each cell reading. For each 10oF (6oC) above 80oF (27oC) add 0.
Battery Charging To minimize possible damage to the battery and allow the battery to be fully charged, the slow charging method is presented here. This charging method can be accomplished with a constant current battery charger which is available in most locations. CAUTION Follow the battery charger manufacturer’s instructions when using a battery charger. NOTE: Using specific gravity of the battery cells is the most accurate method of determining battery condition. 1.

General Information Cutting Unit Operator’s Manual Reelmaster 7000−D (Model 03708) Page 8 − 3 DPA Cutting Units Units DPA Cutting The Cutting Unit Operator’s Manual provides information regarding the operation, general maintenance and maintenance intervals for the DPA cutting units on your Reelmaster machine. Additionally, if optional kits have been installed on the cutting units (e.g. rear roller brush), the installation instructions for the kit includes set−up and operation information.
Special Tools Special tools are available from your Toro Distributor. Some tools may have been supplied with your machine or are available as TORO parts. Gauge Bar Assembly Toro Part Number: 108−6715 Use gauge bar to verify height−of−cut adjustment. Used for Height−of− Cut (HOC) adjustment Used for Height−of− Groomer (HOG) adjustment Figure 2 Bedknife Screw Tool Toro Part Number: TOR510880 This screwdriver−type bit is made to fit Toro bedknife attaching screws.
Plastic Plug Toro Part Number: 94−2703 This plug is used for placement into the side plate bearing housing when the hydraulic reel motor is removed. It prevents dirt and debris from entering the cutting reel bearing area. Figure 5 Cutting Unit Kickstand Toro Part Number: 119−8010−03 The cutting unit kickstand is used to prop up the rear of the cutting unit during service. Use of this tool prevents the bedbar adjusting screws from resting on the work surface.
Diameter/Circumference Measuring Tape Toro Part Number: TOR6023 Spring steel measuring tape for accurately measuring the circumference and outside diameter of cutting reel and other spherical components. Tape calibration is in fixed inch readings (no adjustments). Figure 8 Roller Rebuild Kit Toro Part Number: 115−0803 Bearing Installation Washer This tool kit is used to assemble the cutting unit rollers.
Reel Bearing Installation Tool (cutting units with painted side plates) Toro Part Number: 117−0975 Use the reel bearing installation tool to keep the reel bearing aligned as the cutting unit side plate is installed on the bearing. Figure 11 Cutting Reel Shim Toro Part Number: 125−5611 The cutting reel shim (0.002”) is used to help parallel the bedknife and cutting reel.
Bedknife Top Angle Indicator and Mount Toro Part Numbers: 131−6828 and 131−6829 1 Because the top grind angle on bedknives is critical for edge retention, and therefore after− cut appearance, Toro has developed these service tools for accurately measuring the top grind angle on all bedknives. 2 3 Since there can be variations in the mounting surface of the bedbar, it is necessary to grind the bedknife after installing it to the bedbar. 1.
Factors That Can Affect Cutting Performance There are a number of factors that can contribute to unsatisfactory quality of cut, some of which may be turf conditions. Turf conditions such as excessive thatch, “sponginess” or attempting to cut off too much grass height may not always be overcome by adjusting the cutting unit. It is important to remember that the lower the height−of−cut, the more critical these factors are.
Factor Possible Problem/Correction Reel and bedknife sharpness A reel and/or bedknife that has rounded cutting edges or “rifling” (grooved or wavy appearance) cannot be corrected by tightening the bedknife to reel contact. Grind cutting reel to remove taper and/or rifling. Grind bedknife to sharpen and/or remove rifling. The most common cause of rifling is bedknife to reel contact that is too tight.
Factor Possible Problem/Correction Roller condition and roller type Make sure rollers rotate freely. Repair roller bearings as necessary. See Roller Service in the Service and Repairs section of this chapter. Refer to Cutting Unit Operator’s Manual for roller options. Reelmaster 7000−D (Model 03708) Page 8 − 11 DPA Cutting Units Units A variety of cutting unit accessories are available that can be used to enhance aftercut appearance. Refer to Operator’s Manual for a listing of available accessories.
Adjustments Characteristics If a cutting unit is determined to be out of adjustment, complete the following procedures in the specified order to adjust the cutting unit properly. CAUTION Never install or work on the cutting units or lift arms with the engine running. Always stop engine and remove key first. The dual knob bedknife−to−reel adjustment system incorporated in this cutting unit simplifies the adjustment procedure needed to deliver optimum mowing performance.
Reel Bearing Adjustment (cutting units with painted side plates) NOTE: Cutting units that have aluminum side plates do not require reel bearing adjustment. 4 12 to 15 in−lb (1.4 to 1.7 N−m) To insure cut quality and long life of the cutting reel bearings, periodically check reel bearing adjustment. 1 Check Reel Bearing Adjustment 1. Remove hydraulic reel motor from cutting unit (see Hydraulic Reel Motor Removal in the Service and Repairs section of this chapter). 15 to 17 in−lb (1.7 to 1.
Leveling Rear Roller The precision machined components of the cutting unit frame keep the rear roller and cutting reel in alignment (parallel). If the side plates are disassembled or as the cutting reel wears, a limited amount of side plate adjustment is possible to make sure that the cutting unit is properly aligned. 3 2 4 1 1. Place the assembled cutting unit on a surface plate. 4 2. Make sure that bedknife is properly adjusted to cutting reel. 3.
