Specifications Engine: The 4-cycle, 3-cylinder, overhead valve Mitsubishi diesel engine Model K3D is water cooled and delivers 24.99 HP (18.6 kW) @3,600 rpm. Cylinder bore is 2-7/8 in. (73 mm), stroke is 3- 1/16 in. (78 mm) and displacement is 59.7 cu. in. (979 cc). Compression ratio is 23:1. Crankcase oil capacity with filter is 3.7 qt. (3.5 L). The filter is a full-flow, replaceable, screw-on type. Mechanical centrifugal type governor limits maximum no-load engine speed to 3,200 +/- 50 rpm.
engine off when the traction pedal is engaged with no operator on the seat. Seat Switch—Shuts the engine off if the operator leaves the seat without disengaging the PTO and/or the traction pedal. The engine will not start if the PTO or the traction pedal is engaged.
Before Operating CHECK THE CRANKCASE OIL The engine is shipped with 3.7 quarts (3.5 L) of oil in the crankcase; however, the level of the oil must be checked before and after the engine is first started. 1. Position the machine on a level surface. 2. Disengage the hood latch and open the hood. 3. Remove the dipstick and wipe it with a clean cloth (Fig. 1). Push the dipstick down into the tube and ensure it is fully seated. Pull the dipstick out of the tube and check the level of the oil.
low temperatures (wax appearance, which may plug filters). Number 2-D diesel fuel above 20° F (–7° C) will contribute toward longer life of the pump components. Do not use furnace oil. Furnace oils usually contain heavy cracked distillates which are not suitable for diesel engines. Store fuel outside of buildings in a convenient location. Tipping the front of the tank up slightly will allow contaminants to collect at the lower end away from the outlet. Never empty the tank below 4 in.
If possible, fill the Groundsmaster 325-D fuel tank at the end of each day’s operation. This will prevent possible build-up of condensation inside the fuel tank and possible engine damage. Let the engine thoroughly cool down before refueling. 1. Tip the seat forward and prop it with the support rod so it cannot fall accidentally. Using a clean rag, clean the area around the fuel tank cap. 2. Remove the cap from the fuel tank (Fig.
Expected Ambient Temperature Recommended Viscosity and Type (Extreme) over 90 F SAE 30, Type SF/CC or CD engine oil. (Normal) 40-1 00 F or CD engine oil.

Note: Do not mix engine oil and automatic transmission fluid or hydraulic system component damage may result. When changing fluids, also change the transmission filter.
Controls Traction Pedal (Fig. 5)—The traction pedal moves the machine forward and backward. Using the heel and toe of the right foot, depress the top of the pedal to move forward and the bottom of the pedal to move backward. Ground speed depends on how far you press the pedal. For maximum ground speed with no load, the traction pedal must be fully depressed while the throttle is in the FAST position. Maximum speed forward is approximately 9.5 mph (15 km/hr).
must be evenly adjusted. Lift Lever (Fig. 6)—The hydraulic lift lever has three positions: FLOAT, TRANSPORT and RAISE. To lower the implement to the ground, move the lift lever forward into notch, which is the FLOAT position. To raise the implement, pull the lift lever backward to the RAISE position. After the implement is raised, allow the lift lever to move to the TRANSPORT position. Normally, the implement should be raised when driving from one work area to another, except when descending steep slopes.
contrast, the alternator is not charging the battery when the needle points to the (-) negative side of ammeter. If this happens, repair the charging system to prevent discharge of the battery. Temperature Switch/Gauge and Reset Button (Fig. 7)—The temperature switch/gauge registers the temperature of the coolant in the cooling system. If the coolant temperature gets too high, the engine will shut off automatically. When this happens, turn the ignition key to OFF.
Engine Stop Lever (Fig. 10)—Located on the lower right side of the engine inboard of the air cleaner assembly. Provided as a means to stop the fuel flow, thereby stopping the engine, if an electrical malfunction should occur. Use only for emergencies. Seat Adjusting Levers (Fig. 11)—To adjust a standard seat, push the lever backward and slide the seat to the desired position. Release the lever to lock the seat in place.
Operating STARTING AND STOPPING THE ENGINE IMPORTANT: The fuel system must be bled if any of the following situations have occurred: A. Initial start-up of a new machine. B. The engine has stopped running because of lack of fuel. C. Maintenance has been done on the fuel system components; i.e., filter replaced, separator serviced, etc. Refer to Bleeding The fuel System 1. Ensure the parking brake is set, the PTO lever is in the OFF position (Fig.
NOTE: Do not exceed 1 minute of continuous use or the glow plug prematurely burn out. 5. When the engine is started for the first time, or overhaul of the engine, transmission or axle, operate the machine in forward and reverse for one to two minutes. Also operate the lift lever and the PTO lever to assure proper operation of all parts.
CHECKING THE INTERLOCK SWITCHES The machine has interlock switches in the electrical system. These switches are designed to stop the engine when you get off the seat while either the PTO lever is engaged or the traction pedal is depressed. However, you may get off the seat while the engine is running. Although the engine will continue to run if the PTO lever is disengaged and the traction pedal is released, it is strongly recommended that the engine be stopped before dismounting from the seat.
5. If all the switches operated correctly, the machine can be operated. PUSHING OR TOWING THE TRACTION UNIT In an emergency, the traction unit can be pushed or towed for a very short distance. However, Toro does not recommend this as standard procedure. IMPORTANT: Do not push or tow the traction unit faster than 2 to 3 mph (3 to 4.8 km/hr) because the transmission may be damaged. If the traction unit must be moved a considerable distance, transport it on a truck or trailer.
decreases, and depress the pedal slowly as rpm increases. By comparison, when driving from one work area to another—with no load and cutting unit raised—have the throttle in the FAST position and depress the traction pedal slowly but fully to attain maximum ground speed. Another characteristic to consider is operating the turning pedals that are connected to the brakes.
GREASING BEARINGS, BUSHINGS, GEAR BOX AND BRAKE CABLES The traction unit must be lubricated regularly. If the machine is operated under normal conditions, lubricate all bearings and bushings after every 50 hours of operation. The traction unit bearings and bushings that must be lubricated are: the PTO shaft and yokes (Fig. 15); lift arm pivots(Fig.16); right and left push arm ball joints (Fig. 15); push arm pivot bushings (Fig. 17); PTO pivot housing blocks (Fig. 18); brake pivot bushings (Fig.
