SAFETY INSTRUCTIONS The GROUNDSMASTER 325ĆD 4 WHEEL DRIVE was tested and certified by TORO for compliance with the B71.4Ċ1990 specifications of the American National Standards Institute. Although hazard control and accident prevention partially are dependent upon the design and configuration of the machine, these factors are also dependent upon the awareness, concern, and proper training of the personnel involved in the operation, transport, maintenance, and storage of the machine.
D. Look behind machine before backing up. E. Watch for holes or other hidden hazards. F. Do not drive close to a sand trap, ditch, creek, or hazard. G. Reduce speed when making sharp turns and when turning on a hillside. H. The cutting deck must be lowered when going down slopes for steering control. To maintain machine control, 35 lb. of weight must be mounted on rear of traction unit before using the TRIFLEX 88" cutting unit.
% ! Before disconnecting or performing any work on the hydraulic system, all pressure in system must be relieved by stopping engine and lowering implement to the ground. If the engine must be running to perform maintenance or an adjustment, keep clear of PTO shaft, cutting unit blades, and other moving parts. Do not overspeed the engine by changing the governor settings. Maximum engine speed with no load is 3200 50 rpm.

Use of No. 2ĆD diesel fuel above 20 F (Ć7 C) contributes 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 allows contaminants to collect at the lower end away from the outlet. Never empty the tank below 4 in.
Unscrew dipstick cap (Fig. 23) from the filler neck and wipe it with a clean rag. Screw dipstick cap finger tight onto filler neck. Unscrew the dipstick and check level of oil.

Using the heel and toe of the right foot, depress top of pedal to move forward and bottom of pedal to move backward. Ground speed is proportionate to how far pedal is depressed. For maximum ground speed with no load, traction pedal must be fully depressed while throttle is in FAST position. Maximum speed forward is approximately 9.5 mph (15 km/hr).

The weight adjustment knob may be adjusted for any operator's comfort.
The fuel system must be bled if any of the following situations have occurred: A. Initial start up of a new machine. B. Engine has ceased running due to lack of fuel. C. Maintenance has been performed upon fuel system components; i.e. filter replaced, separator serviced, and so on. Refer to Bleeding Fuel System. the machine in forward and reverse for one or two minutes.
" !" # " ! Turn key in ignition switch to the RUN position. Electric fuel pump will begin operation, thereby forcing air out around air bleed screw on fuel injection pump. Leave key in RUN position until solid stream of fuel flows out around the screw. Tighten screw and turn key to OFF. Sit on seat and start the engine. Raise off the seat and move the PTO lever to ON. The engine should stop within 2Ć3 seconds.
To maintain enough power for the traction unit and implement while operating, regulate traction pedal to keep engine rpm high and somewhat constant. A good rule to follow is: decrease ground speed as the load on the implement increases, and increase ground speed as the load decreases. Therefore, allow traction pedal to move backward as engine rpm decrease, and depress pedal slowly as rpm increase.

The traction unit must be lubricated regularly. If 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: PTO shaft and yokes (Fig. 35); lift arm pivots (Fig. 35); right and left push arm ball joints (Fig. 35); push arm pivot bushings (Fig. 36); PTO pivot housing blocks (Fig. 37); brake pivot bushings (Fig.

Remove boot from button end of seat switch (Fig. 42). Retain boot for reinstallation. Separate switch wire connectors. Install new seat switch to support bracket. Adjust switch height so it is 3/32" (2.4 mm) below top of spring pin.
Remove boot from button end of PTO switch (Fig. 43). Retain boot for reinstallation. Separate switch wire connectors. Assure hose between air cleaner and carburetor is clamped securely in place. Replace the hose if it is cracked or punctured. Check air cleaner body for dents and other damage which could possibly cause an air leak. Replace a damaged air cleaner body. Be sure dust cap is sealing around bottom of air cleaner body.
Service the air cleaner filter every 250 hours or more frequently in extreme dusty or dirty conditions by washing or using compressed air. Replace the element after every six cleanings (1500 hours) or annually, whichever comes first. Remove and service dust cup; refer to Servicing Dust Cup and Baffle. Remove wing nut w/gasket and slide filter element out of air cleaner body (Fig. 45).
Check oil level after each day's operation or each time machine is used. Change oil and filter after first 50 hours operation and every 100 hours thereafter. However, change oil more frequently when engine is operated in dusty or sandy conditions. If possible, run engine just before changing oil because warm oil flows better and carries more contaminants than cold oil. After oil is drained, reinstall drain plug and wipe up any oil that spilled.
Fuel pump is located on inner frame bulkhead to left of drive coupling assembly (Fig. 49). Bleed the fuel system; refer to Bleeding Fuel System. )-# This procedure should be used only if fuel system has been purged of air through normal priming procedures and engine still will not start; refer to Bleeding Fuel System Loosen the pipe connection to the No. 1 nozzle and holder assembly.

Push idler pulley against belt until proper deflection is achieved and tighten idler pulley locknut (Fig. 52).
Press down on front of traction pedal and check travel. There should be approximately 3.50" clearance between end of pedal and floor plate when pedal in fully depressed (Fig. 54). Adjust pump control rod (Fig. 55) to attain dimension. Park vehicle on a level surface and turn engine off. Apply the parking brake, tip seat forward, and actuate pump lever (Fig. 56) to insure assembly is properly seated and operating freely. Correct any discrepancy.

Remove wheel nuts and slide wheel and tire assembly off studs. Rotate brake drum until adjusting slot is at bottom and centered over star nut that adjusts brake shoes (Fig. 61). After attaining desired adjustment, tighten screw on tie rod clamp and re-secure ball joint to mounting bracket.
Remove jack stands or blocking and lower machine to the shop floor. Lubricate filter gasket with proper viscosity and type oil. Then fill filter using the same oil. Adjust the brake cables using step 1. Install filter by hand until gasket contacts mounting head. Then rotate an additional 1/2 turn.
*.! Fluid to operate the power steering is supplied by the hydraulic system transmission charge pump. Cold weather start-up may result in stiff" operation of the steering until the hydraulic system has warmed up. Using proper weight hydraulic oil in system minimizes this condition. Leave machine set for two additional minutes, then remove dipstick and check oil level in axle (Fig. 66). If level is low, add oil until level matches groove in dipstick (Fig. 66).
