Install them whenever the reel drive motors are removed to protect the cutting unit bearings from contamination. 11. Coat the spline shaft of the motor with clean grease and install the motor by rotating the motor clockwise so the motor flanges clear the studs.
Before Operating Checking the Engine Oil The engine is shipped with oil in the crankcase; however, the oil level must be checked before and after the engine is first started. Crankcase capacity is approximately 3.5 quarts (3.3 l) with the filter. Use high-quality engine oil that meets the following specifications: API Classification Level Required: CH–4, CI–4 or higher.
Filling the Fuel Tank The engine runs on No. 2 diesel fuel. The fuel tank capacity is approximately 6 gallons (22.7 l). 1. Clean the area around the fuel tank cap (Fig. 24). 1 2 Figure 24 1 Figure 25 1. Fuel tank cap 1. Radiator screen 2. Remove the fuel tank cap. The cooling system is filled with a 50/50 solution of water and permanent ethylene glycol antifreeze. Check the level of the coolant at the beginning of each day before starting the engine.
3. If the coolant is low, remove the reserve tank cap and add a 50/50 mixture of water and permanent ethylene glycol antifreeze. Do not overfill. Alternate fluid: Mobil EAL 224H This is vegetable–oil based biodegradable oil tested and approved by Toro for this model. This fluid is not as resistant to to high temperatures as standard fluid, so install an oil cooler if required by the operator manual and follow recommended fluid change intervals with this fluid.
Checking the Tire Pressure 1 The tires are over-inflated for shipping. Therefore, release some of the air to reduce the pressure. The correct air pressure is: 2 • Front tires: 8–12 psi • Rear tire: 8–15 psi Checking the Reel-to-Bedknife Contact Each day before operating the machine, check the reel-to-bedknife contact, regardless if the quality of cut had previously been acceptable.
Operation Think Safety First Please carefully read all the safety instructions on pages 3 thru 7. Knowing this information could help you and others avoid injury. The use of protective equipment, such as, but not limited to, for eyes, ears, feet, and head is recommended.

Important Water must be drained from the fuel filter/water separator to avoid serious engine damage; refer to Draining Water from Fuel Filter/Water Separator, page 23. 12 9 10 8 High Temperature Override Button Figure 31 1. 2. 3. 4. 5. 6. 7.
Reel Speed Controls The reel speed controls (Fig. 32) control the RPM of the front and rear cutting units. #1 position is for backlapping. Remaining settings are for mowing operations. See section in manual for operating instructions. 1 1 Figure 34 1. Fuel shut-off (under fuel tank) Break-In Period Only 8 hours of mowing operation is required for the machine break-in period.
Testing the Safety Interlock System 4. Insert the key into the switch and rotate it to On. Hold it in the On position until the glow plug indicator light goes off (approximately 6 seconds). 5. Immediately turn the ignition key to the Start position. Release the key when the engine starts and allow it to move to the On position. Move the throttle control to Slow. Caution If safety interlock switches are disconnected or damaged the machine could operate unexpectedly causing personal injury.
4. To set the reel speed, rotate the knob (Fig. 37) until the indicator arrows are in line with the number designating desired setting. kill, which means that the interlock system is operating correctly. Correct the problem if it is not operating properly. 1 4. Sit on the seat, move the traction pedal to Neutral, move the functional control lever to Neutral, and engage the parking brake. Start the engine. Release the parking brake, move the functional control lever to mow, and rise from the seat.
Important Familiarize yourself with the fact that the No. 1 cutting unit reel is delayed when lowering and raising, therefore, you should practice to try to gain the required timing necessary to minimize the cleanup mowing operation. 4 2 3 1 3. Overlap a minimal amount with the previous cut on return passes. To assist in maintaining a straight line across the green and to keep the machine an equal distance from the edge of the previous cut, establish an imaginary sight line approximately 6 to 10 ft. (1.
Towing the Traction Unit Important The machine should never be stopped on a green with the cutting unit reels operating as damage to the turf may result. Stopping on a wet green with the machine may leave marks or indentations from the wheels. In case of an emergency, the machine can be towed for a short distance (less than 1/4 mile [0.4 km]). However, we do not recommend this as a standard procedure. 6. Finish cutting the green by mowing the outer periphery.

Lubrication The traction unit has grease fittings that must be lubricated regularly with No. 2 General Purpose Lithium Base Grease. If the machine is operated under normal conditions, lubricate all bearings and bushings after every 50 hours of operation. Lubricate fittings immediately after every washing, regardless of the interval listed. The following traction unit bearings and bushings must be lubricated: Figure 42 • Rear wheel hub (1) • Castor bearing (1) • Steering cylinder (2) (Fig.
General Air Cleaner Maintenance 4. Clean the dirt ejection port located in the removable cover. Remove the rubber outlet valve from the cover, clean the cavity and replace the outlet valve. • Check the air cleaner body for damage which could cause an air leak. Replace if damaged. Check the whole intake system for leaks, damage or loose hose clamps. 5. Install the cover orienting the rubber outlet valve in a downward position – between approximately 5:00 to 7:00 when viewed from the end.
Changing Oil and Filter Adjusting the Throttle Control 1. Remove the drain plug and let the oil flow into the drain pan. When the oil stops, install the drain plug. Proper throttle operation is dependent upon proper adjustment of the throttle control. Ensure the throttle control is operating properly. 2. Remove the oil filter. Apply a light coat of clean oil to the new filter gasket. 1. Move the remote throttle control lever to the Slow position (Fig. 47). 3.
Hydraulic Oil Checking the Hydraulic Lines and Hoses Service Interval/Specification Inspect the hydraulic lines and hoses daily for leaks, kinked lines, loose mounting supports, wear, loose fittings, weather deterioration and chemical deterioration. Make all necessary repairs before operating. Change the hydraulic oil after every 800 operating hours. If the oil becomes contaminated, contact your local Toro distributor because the system must be flushed.
2. Loosen the jam nut and adjust the clevis accordingly (Fig. 49). 2 3 D. Rotate the eccentric until creep does not occur in either direction. When the wheel stops rotating, tighten the nut locking the eccentric and the adjustment (Fig. 50). Verify the adjustment with the throttle in the Slow and Fast position. 4 E. From each side of the bulkhead, tighten the locknuts evenly, securing the traction cable to the bulkhead (Fig. 50). Do not twist the cable.
Adjusting the Mowing Speed The machine is adjusted at the factory, but speed may be varied if desired. 1. Loosen the jam nut on the trunnion capscrew (Fig. 52). 2. Loosen the nut securing the lock and mow brackets on the pedal pivot. 1 Figure 53 1. Flow control valve 2 2. Loosen the set screw on the adjusting knob on the flow control. 1 3. Rotate the knob 1/4 turn counterclockwise if the center cutting unit is dropping too late or 1/4 turn clockwise if the center cutting unit is dropping too early.
2. Adjust the belt to the proper tension and tighten the bolts. Keep the top of the battery clean by washing it periodically with a brush dipped in ammonia or bicarbonate of soda solution. Flush the top surface with water after cleaning it. Do not remove the fill caps while cleaning the battery. Servicing the Battery The battery cables must be tight on the terminals to provide good electrical contact.
Storing the Battery 1. Position the machine on a clean, level surface, lower the cutting units, stop the engine, engage parking brake, and remove the key from the ignition switch.
