Traction Circuit The hydraulic pump assembly is driven by a coupling attached to the engine flywheel. The pump assembly consists of a three section gear pump, a gerotor charge pump, and a variable displacement piston pump. Pushing the top of 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 two fixed displacement motors.

Lower Cutting Units Gear pump section (P3) provides oil flow through the steering control valve and lift manifold to all cutting unit lift cylinders. Maximum circuit pressure (1500 PSI/104.0 bar) is limited by a relief valve in the gear pump (R3). When the cutting units are in the raised position, flow from the gear pump (P3) passes through the steering control valve and into the lift manifold. All lift manifold solenoid valves are de-energized and flow is directed to the hydraulic reservoir.

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.) Before Performing Hydraulic Tests 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.
TEST NO. 1: Traction Circuit Charge Pressure 1. Make sure hydraulic oil is at normal operating temperature by operating the machine for approximately 10 minutes. 2. Make sure machine is parked on a level surface with the cutting units lowered and off. Make sure engine is off. CAUTION Prevent personal injury and/or damage to equipment. Read all WARNINGS, CAUTIONS, and Precautions for Hydraulic Testing at the beginning of this section. 3. Connect a 1000 PSI gauge onto charge pressure test port (Fig. 13).
TEST NO. 2: Traction Circuit Pressure 1. Make sure hydraulic oil is at normal operating temperature before doing test. 2. Drive machine to an open area, lower cutting units, and shut off the engine. 2 3. Connect a 10,000 psi gauge to traction circuit test port for function to be checked (Fig. 14). 4. Start the engine and move throttle to full speed (approx. 3200 RPM). 1 CAUTION Prevent personal injury and/or damage to equipment.
TEST NO. 3: Cutting Unit Drive Circuit Pressure Note: The front cutting unit drive circuit is protected by relief valve R1 and the rear circuit by relief valve R2. See Hydraulic Flow Diagrams at the beginning of this chapter. 2 1 1. Make sure hydraulic oil is at normal operating temperature by operating the machine for approximately 10 minutes. 2. Make sure machine is parked on a level surface with the cutting units lowered and off. Make sure engine is off. Figure 15 CAUTION 1.
TEST NO. 4: Gear Pump Section P3 Flow and Relief Valve Pressure (Using Tester with Pressure Gauges and Flow Meter) 1. Make sure hydraulic oil is at normal operating temperature by operating the machine for approximately 10 minutes. 1 2. Make sure machine is parked on a level surface with the cutting units lowered and off. Make sure engine is off. CAUTION Prevent personal injury and/or damage to equipment. Read all WARNINGS, CAUTIONS, and Precautions for Hydraulic Testing at the beginning of this section.
TEST NO. 5: Gear Pump Section P1 & P2 Flow (Using Tester with Pressure and Flow Capabilities) Over a period of time, the gears and wear plates in the pump can wear. A worn pump will by-pass oil and make the pump less efficient. Eventually, enough oil can bypass to cause the reels to stall in heavy cutting conditions. Continued operation with a worn, inefficient pump can generate excessive heat and cause damage to seals and other components in the hydraulic system. 1 2 1.
TEST NO. 6: Reel Drive Motor Cross-Over Relief Pressure Use a tee fitting to install pressure gauge in inlet line of motor being tested. NOTE: Inlet is front hose. R7 R7 R7 R7 R7 M4 High Pressure Low Pressure Flow R7 M1 M5 Reel Manifold Block Figure 19 Note: One way to find a bad reel motor is to have another person observe the machine while mowing in dense turf. A bad motor will run slower, produce fewer clippings, and may cause marcelling (or a washboard appearance) on the turf. 1.
2. Determine which reel motor is malfunctioning. Note: The reel motors are connected in series. To isolate a faulty motor, you may have to test all three motors in the circuit by starting with the upstream motor first. 3. Lower cutting units, engage parking brake and stop the engine. 4. Install a tee fitting between the motor inlet fitting and hose. Install a 5000 PSI pressure gauge on the tee fitting (Fig. 19). 5. Set reel speed control to the full speed position.
TEST NO. 7: Reel Drive Motor Efficiency (Using Tester with Pressure Gauges and Flow Meter) Outlet hose Case drain hose High Pressure Low Pressure Case Drain Flow R7 R7 R7 Install tester in series between fitting and hose at motor outlet. NOTE: Outlet is rear hose. R7 R7 M4 R7 M1 M5 Disconnect case drain hose (small diameter hose) where it connects to the traction unit. Reel Manifold Block Figure 20 Note: Over a period of time, a reel motor can wear internally.
1. Make sure hydraulic oil is at normal operating temperature by operating the machine for approximately 10 minutes. Make sure the hydraulic tank is full. 2. Make sure machine is parked on a level surface with the cutting units lowered and off. Make sure engine is off and the parking brake is engaged. 3. Read Precautions for Hydraulic Testing. Note: The reel motors are connected in series.
Adjustments Adjust Manifold Relief Valve (R1 and R2) The hydraulic reel circuit is equipped with a relief valve. Valve (R1) is preset at the factory to 3000 PSI. Valve (R2) on Reelmaster 6500--D is set to 2000 PSI. Valve (R2) on Reelmaster 6700--D is set to 3000 PSI. However, an adjustment may be required if the setting proves to be off after testing (see TESTING). If an adjustment is required proceed as follows: 2 WARNING Never adjust the relief valve with the hydraulic system pressurized.
Adjust Traction Drive for Neutral The machine must not creep when traction pedal is released. If it does creep, an adjustment is required. 1 1. Park machine on a level surface, shut engine off and lower cutting units to the floor. Depress only the right brake pedal and engage the parking brake. 2. Jack up left side of machine until front tire is off the shop floor. Support machine with jack stands to prevent it from falling accidentally.
Adjust Cutting Unit Drop Rates (Serial Numbers Below 280000000) The cutting unit lift/lower circuit is equipped with adjustable flow control valves to ensure the cutting units do not drop too quickly and damage the turf. Center (#1), Outside Front (#4 & 5) and Rear (6700-D #6 & 7) Cutting Units (Fig. 23) 1. Locate valve behind access panel above operator’s platform. 1 3 3 2 2. Loosen setscrew on valve and rotate valve approximately 1/2 turn clockwise. 3.
Service and Repairs General Precautions for Removing and Installing Hydraulic System Components Before Repair or Replacement of Components After Repair or Replacement of 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 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. If fluid is injected into the skin, it must be surgically removed within a few hours by a doctor familiar with this type of injury. Gangrene may result from such an injury.
Charge Hydraulic System IMPORTANT: Change hydraulic oil filter whenever hydraulic components are repaired or replaced. 1. Park machine on a level surface, and turn the engine off. 2. Make sure all hydraulic connections, lines, and components are secured tightly. 3. If component failure was severe or the system is contaminated, flush and refill hydraulic system and tank (see Flush Hydraulic System). 4. Make sure hydraulic reservoir is full. Add correct oil if necessary (see Check Hydraulic System Fluid). 5.
Change Hydraulic Fluid Change hydraulic fluid after every 800 operating hours, in normal conditions. If fluid becomes contaminated, contact your local TORO distributor because the system must be flushed. Contaminated fluid looks milky or black when compared to clean oil. 1 1. Turn engine off and raise hood. 2. Remove drain plug from bottom of reservoir and let hydraulic fluid flow into drain pan (Fig. 25). Reinstall and tighten plug when hydraulic fluid stops draining.
Replace Hydraulic Oil Filter The hydraulic system filter head is equipped with a service indicator. With the engine running, view the indicator, it should be in the GREEN zone. When the indicator is in the RED zone, the filter element should be changed. IMPORTANT: Use only the Toro replacement filter recommended for this product (see parts catalog or service reference decal on unit). Use of any other filter may void the warranty on some components. 1 2 1.

Diagnostics: S Do troubleshooting by connecting one of the following devices to the loopback connector: - Diagnostic ACE (with the correct overlay). - TOROPC and a personal computer (authorized Toro distributor only). Understanding the Diagnostic Lamps Red Diagnostic Lamp (located on steering tower) Functions: S ON - When glow plug circuit is energized.
Using the ACEt Diagnostic Display The primary electronic controller controls most machine functions. The controller determines what function is required for various input switches (i.e. seat sensor, key switch, etc.) and energizes the outputs to actuate solenoids or relays for the requested machine function. 1 For the electronic controller to control the machine as desired, each of the inputs, outputs must be connected and functioning properly.
B. The Diagnostic ACE will illuminate the LED associated with each of the inputs when that input switch is closed. Individually, change each of the switches from open to closed (i.e., sit on seat, engage traction pedal, etc.), and note that the appropriate LED on Diagnostic ACE will blink on and off when corresponding switch is closed. Repeat on each switch that is possible to be changed by hand. C.
IMPORTANT: The display will show eight (8) individual records with the fault displayed on the 8th record. Each record will be displayed for 10 seconds. Be sure to have the Diagnostic Tool display on Outputs to see fault. The Problem circuit will be flashing. Records will repeat until key is turned off. Unit will not start in this mode. Clearing the Fault Memory (Diagnostic Tool not required) 1. Rotate ignition key to Off position. 2. Turn Backlap Switch to the Front or Rear Backlap position. 3.

Solenoid SV1 or circuit wiring is faulty. Solenoid SV2 or circuit wiring is faulty. A hydraulic problem exists (see Troubleshooting section of Chapter 4 - Hydraulic System). Front center cutting unit #1 will not raise or lower, but the other cutting units will raise and lower. Solenoid SV3 or circuit wiring is faulty.
Electrical System Quick Checks Battery Test (Open Circuit Test) This is a simple test used to determine the condition of the battery at rest. Tool required: Digital Multimeter - DC volts setting. Test instructions: Set the multimeter to the DC Volts setting. The battery should be at a temperature of 60_ to 100_ F. The ignition key should be off and all accessories turned off.
Glow Plug System Test This is a fast, simple test that can help you determine a Glow Plug system’s integrity and operation. The test should be run anytime hard starting (cold) is encountered on a diesel engine equipped with a Glow system. Remember - there are 2 types of Glow Plug systems that Toro uses: 1. Systems with resistors (Glow Plug Indicators) in series (Reelmaster 450/4500-D, Groundsmaster 325-D, etc.). 2.
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 doing a continuity check). NOTE: For more component testing information, see the Kubota Workshop Manual, Diesel Engine, 05 Series at the end of Chapter 3 - Kubota Diesel Engines.
Glow and Start Relays The glow relay and the start relay are mounted to the right side frame member below the operator’s seat. Note: Prior to taking small resistance readings with a digital multi meter, short the test leads together. The meter will display a small resistance value (usually 0.5 ohms or less). This resistance is due to the internal resistance of the meter and test leads. Subtract this value from from the measured value of the component you are testing.
Fuses The fuse blocks are located under the control panel and inside the control console. 1 Identification, Function, and Wiring The fuses are held in two fuse blocks. Use Figure 20 to identify each individual fuse and its correct amperage. Each fuse holder has the following functions and wire connected to it. 2 Fuse 1A A.

It is mounted on the engine block near the injection pump. 1 In Place Testing Note: Prior to taking small resistance readings with a digital multimeter, short the test leads together. The meter will display a small resistance value (usually 0.5 ohms or less). This resistance is due to the internal resistance of the meter and test leads.
Run (ETR) Solenoid (Solenoid With 2 Wire Connector) The run (ETR) solenoid must be energized for the engine to run. It is mounted on the engine block near the injection pump. 2 1 In Place Testing Note: Prior to taking small resistance readings with a digital multimeter, short the test leads together. The meter will display a small resistance value (usually 0.5 ohms or less). This resistance is due to the internal resistance of the meter and test leads.
Fuel Gauge Sender The sender is located on top of the fuel tank under the right, front fender. 1. Remove blue/green wire and black ground wire from the sender. 2 2. Remove round head screws and lock washers from the sender and fuel tank. 3. Remove sender and gasket from the fuel tank. Clean any fuel from the sender. Note: Before taking small resistance readings with a digital multimeter, short test leads together. The meter will display a small resistance value.
Fuel Gauge The fuel gauge can be tested using a new gauge as a substitute or by the use of a DC voltage source and a variable resistance box. CAUTION Make sure the voltage source is turned OFF before connecting it to the electrical circuit to avoid electrical shock and prevent damaging the gauge. VARIABLE RESISTANCE 14 VDC + 0.01 VDC 1.

Reel Backlap Switches The front and rear backlap switches are attached to the reel hydraulic manifold block (Fig. 45). When the backlap control valve (MD1 or MD2) is in the Backlap position, the switch contacts close. This feature allows only one person to backlap any of the reels. The backlap switch circuit also prevents reels from raising during backlapping. When the backlap control valve (MD1 or MD2) is in the Mow position, the switch contacts open.
Seat Sensor The sensor consists of two parts. The reed switch is located on the lower bracket of the seat suspension mechanism and has a normally open contact. The switch actuator is located on the upper plate of the seat suspension mechanism and is made of a magnetic material. When the operator sits in the seat, the magnetic field of the actuator is positioned near the reed switch and the contact in the switch closes.
Cutting Unit Down Sensor(s) The cutting unit down switch is a normally open (NO) reed switch located on the left front lift arm that closes when the lift arm is in the lowered position. As the lift arm is lowered, a bracket on the lift arm comes close to the switch, causing the reed switch to close and complete the circuit. This sensor can be tested using the “Input Checks” feature of the ACE Diagnostic tool. 1 The sensor can also be tested manually. 1.

Maintenance Changing Planetary Gear Drive Lubricant Planetary gear drive lubricant should be changed every 800 hours of operation. There are 2 separate oil reservoirs (one for each front wheel) that require draining and refilling with SAE 85W-140 gear lube. 1. With machine on level surface, position wheel so the check/drain plug is at lowest position (Fig. 1). 1 2. Remove both plugs from the bottom of the brake housing and allow the oil to drain (Fig. 2). 3.
Changing Rear Axle Lubricant Rear axle lubricant should be changed every 800 hours of operation. Rear axle lubricant should be SAE 85W-140 gear lube. 1. Position machine on a level surface. 2. Clean area around the check plugs, drain plugs, and fill/vent plug (Fig. 3, 4, & 5). 3. Remove check plugs and fill/vent plug to allow easier rear axle draining. 4. Remove drain plugs and allow axle lubricant to drain into drain pans. 1 2 5. Reinstall all drain plugs after complete axle draining. 6.
Adjustments Service Brake Adjustment Adjust the service brakes when there is more than 1 inch of “free travel” of the brake pedal, or when the brakes do not work effectively. Free travel is the distance the brake pedal moves before braking resistance is felt. 1 1. Disengage locking pin from brake pedals so both pedals work independently of each other. 2. To reduce free travel of brake pedals, tighten the brakes - loosen front nut on threaded end of brake cable.
Rear Wheel Toe-in Adjustment After every 800 operating hours or annually, check rear wheel toe-in. To check toe-in, rotate the steering wheel so the rear wheels point straight ahead. Measure the center-tocenter distance, at axle height, in front and rear of steering tires. Front measurement should be 1/4” (6.4 mm) less than the rear measurement. If toe-in is not within specifications, an adjustment is required. 2WD Traction Units 1 1. Loosen clamps at both ends of tie rod (Fig. 7). 2.

Specifications Figure 1 REEL CONSTRUCTION: Fairway reels. All welded. 5, 7 or 11 blades. BEDKNIFE AND BEDBAR ADJUSTMENT: Single point adjustment mechanism. HEIGHT OF CUT RANGE: 5 Blade - 1” to 1-3/4” (25-44 mm) 7 Blade - 1/2” to 1” (13-25 mm) 11 Blade - 3/8” to 3/4” (10-19 mm) ROLLERS: Front rollers: 3” (76 mm) diameter Wiehle rollers. Optional 3“ (76 mm) diameter full rollers, Part No. 93-3040, are available for the front position. Rear rollers: 3” (76 mm) diameter full rollers.
Special Tools Order special tools from your Toro distributor. Some tools may have been supplied with your machine or available as TORO parts. Some tools may also be available from a local supplier. Gauge Bar Assembly Use gauge bar to verify height of cut and bedknife attitude. Toro P/N 98-1852 Figure 2 Angle Indicator Use with Gauge Bar Assembly to verify bedknife attitude.
Bedknife Screw Tool - TOR510880 This screwdriver-type bit is made to fit Toro bedknife attaching screws. Use this bit with a torque wrench to secure the bedknife to the bedbar. Make sure bedbar threads are clean and use new screws. Tighten screws to a torque of 250 - 300 in.lb. (28 - 34 Nm) starting in the middle of the bedknife (Fig. 27). Note: Remove all rust, scale and corrosion from bedbar surface before installing bedknife. DO NOT use an air impact wrench with this tool.
Troubleshooting 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 machine. It is important to remember that the lower the height of cut, the more critical these factors are. Remember that the “effective” or actual height of cut depends on cutting unit weight and turf conditions.
Factor Possible Problem/Correction 5. Bedknife to reel adjustment. Check bedknife to reel contact daily. Bedknife must have light contact all across reel. No contact will cause cutting edges to become dull. Excessive contact accelerates wear; quality of cut may be adversely affected. Adjust so you paper can be pinched between reel and bedknife without tearing when inserted from the front, and cuts cleanly when inserted at a right angle (along entire length of bedknife).
Set-up and Adjustments IMPORTANT: Toro strongly recommends the use of a leveling plate when setting-up or adjusting any reel type cutting unit. The leveling plate will help to ensure accurate and consistent adjustments. RIGHT Note: Right and left ends of cutting unit is determined by standing in the operator’s position (Fig. 8). 1. Check each end of the reel for grease. Grease should be visibly evident in the reel bearings and internal splines of reel shaft. 2.
Bedknife to Reel Adjustment IMPORTANT: The reel and bedknife must be parallel to insure the cutting unit cuts grass across the bedknife, and the reel and bedknife wear evenly. Note: Toro recommends light contact between the reel and bedknife. However, for dry and/or sparse conditions a .001-.002” (.03-.05 mm) clearance may be required to prevent heat buildup which can cause uneven wear in the reel and bedknife. Note: A 3/4 inch (19 mm) wrench is needed to rotate bedknife adjustment knob.
C. Recheck reel to bedknife contact on both ends of the bedknife. If necessary, repeat step B. Note: Reel to bedknife contact may become too tight or too loose after previous adjustment; therefore, turn bedknife adjustment knob, accordingly, for light contact. D. Retighten pivot hub lock nuts. Note: Recheck if paper cuts on both ends, to insure the bedknife did not move when re--tightening the pivot hub lock nuts.
Checking or Adjusting Attitude (Used Cutting Units) As a starting point for adjusting cutting unit attitude, the cutting unit may be set up using the dimensions from the New Cutting Unit Set Up Guide found in the Cutting Unit Operator’s Manual. However, because of wear to the bedknife and reel, the following procedure must be used to ensure the correct attitude setting for reels that have been used for more than just a fews hours. 1 1. Rotate cutting unit backward to gain access to reel and bedknife. 2.
Leveling Front Roller IMPORTANT: Toro strongly recommends the use of a leveling plate when setting--up or adjusting any reel type cutting unit. The leveling plate will help to ensure accurate and consistent adjustments. Contact your local Toro Distributor for ordering a leveling plate. 1. Position cutting unit on a flat surface. 1 Note: The bar thickness does not affect the adjustment. The recommended bars keep the cutting unit more balanced during the adjustment.
Final Height of Cut Adjustment 1. Rotate the cutting unit vertical and place the gauge bar across front and rear rollers (Fig. 18). 2. Adjust rear roller until it contacts the gauge bar on both sides. Note: Make sure gauge bar is in contact with the front roller at all times to keep desired height-of-cut. 1 3. Slide gauge bar toward the end of the cutting unit to remove. Gauge bar can now be utilized to set remaining cutting units on machine. 3 2 Figure 18 1. First Screw 2. Second Screw 3.
Rear Shield Adjustment Under most conditions, best dispersion is attained when rear shield is closed (front discharge). When conditions are heavy or wet, rear shield may be opened. 1. To open rear shield, loosen flange head capscrews securing shield to right side plate, rotate shield to open position and tighten screw.
Daily Adjustments Prior to each day’s mowing, or as required, each cutting unit must be checked to verify proper bedknife--to--reel contact. This must be performed even though quality of cut is acceptable. 1. Lower cutting units onto a hard surface, shut off engine and remove key from ignition. 2. Slowly rotate reel in reverse direction listening for reel--to--bedknife contact. If no contact is evident, turn bedknife adjusting knob clockwise, one click at a time, until light contact is felt and heard. 3.
DANGER TO AVOID PERSONAL INJURY, NEVER PLACE HANDS OR FEET IN REEL AREA WHILE ENGINE IS RUNNING. CHANGING ENGINE SPEED WHILE BACKLAPPING MAY CAUSE REELS TO STALL. NEVER CHANGE ENGINE SPEED WHILE BACKLAPPING. ONLY BACKLAP AT IDLE ENGINE SPEED. NEVER ATTEMPT TO TURN REELS BY HAND OR FOOT WHILE ENGINE IS RUNNING. 1 Figure 22 1. Long Handle Brush 6. Select either front, rear, or both backlap knobs to determine which reels will be backlapped. 7. Move Enable/Disable switch to Enable position.

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. Turf compensation spring adjustment Refer to Traction Unit Operator’s Manual for adjustment procedure. Cutting unit accessories A variety of cutting unit accessories are available that can be used to enhance aftercut appearance.
Set Up and 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 To insure cut quality and long life of the cutting reel bearings, periodically check reel bearing adjustment. 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). 2. Loosen bedknife to reel adjustment until no contact exists (see Cutting Unit Operator’s Manual). CAUTION Contact with the reel, bedknife or other cutting unit parts can result in personal injury.
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.

Service and Repairs Hydraulic Reel Motor IMPORTANT: When performing maintenance procedures on the cutting units, carefully position the cutting unit reel motors to prevent damage to the motors or hydraulic hoses. 2 1 4 1 5 Removal 1. Park machine on a clean and level surface, lower cutting units completely to the ground, stop engine, engage parking brake and remove key from the ignition switch. 2 FRONT 6 2.
Backlapping DANGER 2 TO AVOID PERSONAL INJURY OR DEATH: D Never place hands or feet in the reel area while the engine is running. D When backlapping, run engine at idle speed only. D While backlapping, the reels may stall and then restart. D Do not attempt to restart reels by hand or foot. D Do not adjust reels while the engine is running. D If a reel stalls, stop engine before attempting to clear the reel. D Reel motors are connected in series: rotating one motor causes rotation in other motors.
9. To make an adjustment to the cutting units while backlapping, turn reels OFF by moving the Lower Mow/ Raise lever rearward; move the Enable/Disable switch to Disable and turn the engine OFF. After adjustments have been completed, repeat steps 5--8. Top Face Relief Angle Front Face Front Angle 10.When the backlapping operation is completed, run a file across the front face of the bedknife. This will remove any burrs or rough edges that may have built up on the cutting edge. 11.
