General Information Operator’s Manual The Operator’s Manual provides information regarding the operation, general maintenance procedures and maintenance intervals for your Groundsmaster machine. Refer to that publication for additional information when servicing the machine. Pushing Traction Unit In case of emergency, your Groundsmaster can be pushed for a very short distance. However, Toro does not recommend this as a standard procedure. 1 2 Hydraulic System 1. Make sure that engine is not running. 2.
PAGE 42
Traction Circuit Component Failure The traction circuit on Groundsmaster 360 machines is a closed loop system that includes the dual piston (traction) pump and either two (2) or four (4) wheel motors. If a component in the traction circuit should fail, debris and contamination from the failed component will circulate throughout the traction circuit. This contamination can damage other components in the circuit so it must be removed to prevent additional component failure.
PAGE 43
Hydraulic Hoses Hard, cracked, cut, abraded, charred, leaking or otherwise damaged hose. Kinked, crushed, flattened or twisted hose. Blistered, soft, degraded or loose hose cover. Cracked, damaged or badly corroded hose fittings. When replacing a hydraulic hose, be sure that the hose is straight (not twisted) before tightening the fittings. This can be done by observing the imprint (layline) on the hose.

Hydraulic Fitting Installation (SAE Straight Thread O−Ring Fitting into Component Port) Non−Adjustable Fitting (Fig. 5) 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.
PAGE 46
Adjustable Fitting (Fig. 7) 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 Circuits: 2WD Machines The angle of the pump swash plates determines pump flow and ultimately traction speed. When the traction pedal is moved a small amount, a small swash plate rotation results in low pump output and lower traction speed. When the traction pedal is moved fully, the pump swash plates rotate fully to provide maximum pump output flow and traction speed.

Steering Circuits: 2WD Machines A single section gear pump is directly coupled to the transmission which is driven by the engine. This gear pump supplies hydraulic flow for both the steering and lift/lower circuits. Hydraulic pump flow from the gear pump is routed to the steering control valve first so the steering circuit has priority. The pump takes its suction from the hydraulic tank. Steering circuit pressure is limited to 1800 PSI (125 bar) by a relief valve located in the gear pump.

Steering Circuit: 4WD Machines The gear pump, steering control valve and steering cylinders used on 4WD machines are the same as the hydraulic components used on 2WD machines. The steering circuit on 4WD machines, therefore, operates basically the same as the steering circuit on 2WD machines. Refer to Steering Circuit: 2WD Machines in this section for information on steering system operation. In this switch position, the steering control manifold solenoid valve is not energized.

Lift Circuit: Lower When the deck lift switch is in its neutral state, flow from the gear pump bypasses the lift cylinder and is routed through the deck lift manifold directly to the oil cooler and then to the transmission. The transmission case drain allows oil to return to the hydraulic tank. NOTE: The engine must be running to allow the cutting deck to be lowered. When the front of the deck lift switch is depressed, the deck will lower fully and enter the float position.

PTO Circuit The transmission used on Groundsmaster 360 machines includes a hydraulic, multi−plate clutch that is used to engage the PTO. Hydraulic flow for PTO clutch engagement is provided by the transmission charge pump. When the PTO switch is turned off (pushed down), the transmission solenoid valve is de−energized and the PTO clutch is disengaged. The integral PTO brake is applied to control the stopping rate of the drive shaft and cutting deck.

Special Tools Order 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 the Testing section of this chapter.
PAGE 63
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.
PAGE 64
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.

Troubleshooting The chart that follows contains suggestions that can be used to assist in diagnosing hydraulic system performance issues. The suggestions are not all−inclusive. Also, consider that there may be more than one cause for a machine problem. Refer to the Testing section of this Chapter for precautions and specific hydraulic test procedures.
PAGE 66
Traction Circuit Problems Problem Possible Causes Traction response is sluggish. Transmission bypass valve(s) is open or defective. Brake is dragging or binding. Hydraulic oil is very cold. Transmission check valve, relief valve and/or flushing valve is leaking. Charge pressure is low. Transmission or wheel motor(s) is worn or damaged.
PAGE 67
Traction Circuit Problems (Continued) Problem Possible Causes Wheel motor will not hold load in neutral. Make up fluid from charge pump is not available. NOTE: Machine may not be completely stationary if parked on an incline without the parking brake engaged. Check valves in transmission are damaged. On 4WD machine, PD1 or PD2 cartridge in CrossTraxTM AWD control manifold is leaking or is damaged. Valve plate(s) in transmission is worn or damaged.
PAGE 68
PTO Circuit Problems Problem Possible Causes Cutting deck blades will not turn. Cutting deck problem exists (see Chapter 7 − Cutting Deck). An electrical problem exists that prevents PTO from engaging (see Chapter 5 − Electrical System). The engine coolant temperature is excessive. Transmission solenoid valve is stuck. Transmission charge pump is damaged (traction charge circuit also affected). Transmission pressure valve is faulty. Cutting deck blade(s) turn too slowly. Engine speed is too low.

Steering and Lift/Lower Circuit Problems Problem Possible Causes Gear pump is noisy (cavitation). Hydraulic tank oil level is low. Hydraulic oil is very cold. Suction line is restricted. Suction line has an air leak. Steering inoperative or sluggish. Steering components (e.g. steering forks, steering arms, tie rods, steering cylinder ends) are binding and need to be greased. Steering components (e.g. steering forks, steering arms, tie rods, steering cylinder ends) are worn or damaged.
PAGE 70
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). 1. Clean machine thoroughly before disconnecting or disassembling any hydraulic components. Always keep in mind the need for cleanliness when working on hydraulic equipment. Contamination can cause excessive wear or binding of hydraulic components.
PAGE 71
2. If a PTO circuit problem exists, consider performing the PTO Pressure Valve Test. Which Hydraulic Tests Are Necessary? Before beginning any hydraulic test, identify if the problem is related to the traction circuit, PTO circuit, lift/lower circuit or steering circuit. Once the faulty system has been identified, perform tests that relate to that circuit. 1.

NOTE: Over a period of time, a wheel motor can wear internally. A worn motor may bypass oil internally causing the motor to be less efficient. Eventually, enough oil loss will cause the wheel motor to stall under heavy load conditions. Continued operation with a worn, inefficient motor can generate excessive heat, cause damage to seals and other components in the hydraulic system and affect overall machine performance.

Service and Repairs General Precautions for Removing and Installing Hydraulic System Components Before 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 deck and stop engine. Remove key from the ignition switch. 6. Put clean caps or plugs on any hydraulic lines, hydraulic fittings and components left open or exposed to prevent contamination. Cap the opening as soon as line or port is exposed.
PAGE 95
Flush Hydraulic System IMPORTANT: Flush the hydraulic system any time there is a severe component failure or if the system is contaminated (oil appears milky, black or contains metal particles). IMPORTANT: Use only hydraulic fluids specified in Operator’s Manual. Other fluids may cause system damage. Use of biodegradable hydraulic fluid in Groundsmaster 360 machines is not recommended.
PAGE 96
Filtering Closed−Loop Traction Circuit Filtering of a closed−loop hydraulic system after a major component failure (e.g. transmission piston pump or 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.
PAGE 97
IMPORTANT: While engaging the traction circuit, monitor the indicator on the high flow hydraulic filter. If the indicator should show red, either reduce pressure on the traction pedal or reduce engine speed to decrease hydraulic flow through the filter. IMPORTANT: If using a filter that is not the bi−directional Toro high flow filter, do not press the traction pedal in the reverse direction.
PAGE 98
Charge Hydraulic System NOTE: When initially starting the hydraulic system with new or rebuilt components such as wheel motors, gear pump or lift cylinder, it is important that the hydraulic system be charged properly. Air must be purged from the system and its components to reduce the chance of damage. IMPORTANT: Change hydraulic oil filter whenever hydraulic components are repaired or replaced. 1. Park machine on a level surface with engine off. 2.

General Information Cutting Deck Specifications Several cutting decks are available for the Groundsmaster 360. Refer to the Operator’s Manual for specifications and optional accessories for the cutting deck used on your Groundsmaster. Operator’s Manual The Operator’s Manual provides information regarding the operation, general maintenance and maintenance intervals for the cutting deck on your Groundsmaster machine. Refer to that publication for additional information when servicing the cutting deck.
PAGE 307
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 machine. It is important to remember that the lower the height−of−cut, the more critical these factors are.
