Filling the Fuel Tank The cooling system is filled with a 50 / 50 solution of water and permanent ethylene glycol anti–freeze. Check level of coolant in expansion tank at beginning of each day before starting the engine. Capacity of cooling system is 6 quarts (5.6 l). Danger Under certain conditions, diesel fuel and fuel vapors are highly flammable and explosive. A fire or explosion from fuel can burn you and others and can cause property damage.
Checking the Rear Axle damage caused by improper substitutions, so use only products from reputable manufacturers who will stand behind their recommendation. The rear axle has three separate reservoirs which use SAE 80W-90 wt. gear lube. Although the axle is shipped with lubricant from the factory, check the level before operating the machine. Universal Tractor Hydraulic Fluid Mobil Mobil Fluid 424 Amoco 1. Position the machine on a level surface.
Tilt Steering Control 3. Remove check plug. Fluid level should be up to hole in clutch. If fluid level is low, add Mobil Fluid 424. Clutch should be approximately 1/3 full. The tilt steering control is a lever on right side of steering column (Fig. 27). Pull lever rearward to adjust steering wheel to desired fore or aft operating position and push lever forward to lock adjustment. 4. Install check plug. Note: Do not use engine oil (i.e. 10W30) in bidirectional clutch.
Charge Indicator TRANSPORT position. Normally, implement should be raised when driving from one work area to another, except when descending steep slopes. Illuminates when system charging circuit malfunctions (Fig. 29). Caution Engine Coolant Temperature Warning Light The exposed, rotating blades of the cutting unit or other implements are hazardous. The light illuminates and engine shuts down when coolant reaches a excessively high temperature (Fig. 29).
Throttle Control Release key when engine starts. If additional preheat is required, turn key to OFF position then to ON / preheat position. Repeat process as required. The throttle (Fig. 29) is used to operate engine at various speeds. Moving throttle forward increases engine speed—FAST; backward decreases engine speed—SLOW. The throttle regulates the speed of the cutter blades or other implement components and, in conjunction with traction pedal, controls ground speed of the traction unit. 4.
To check operation of interlock switches: 3. Open the air bleed screw on the fuel injection pump (Fig. 31). 1. Drive the machine slowly to a large, relatively open area. Lower cutting unit, stop the engine and apply parking brake. 2. Sit on seat. Move PTO lever to ON position. With the traction pedal in neutral position, try to start the engine. The engine should not crank. If the engine cranks, there is a malfunction in the interlock system that should be corrected before beginning operation. 3.
Another characteristic to consider is the operation of the turning pedals that are connected to the brakes. The brakes can be used to assist in turning the machine. However, use them carefully, especially on soft or wet grass because the turf may be torn accidentally. Another benefit of the turning brakes is to maintain traction. For example: in some slope conditions, the uphill wheel slips and loses traction.
Maintenance Note: Determine the left and right sides of the machine from the normal operating position. Recommended Maintenance Schedule Maintenance Service Interval Maintenance Procedure After first 10 hours • • • • Check the PTO belt tension. Check the fan and alternator belt tension. Change the transmission filter. Torque the wheel lug nuts. After first 50 hours • • • • Change the engine oil and filter. Check engine RPM. Check the PTO belt tension.
Daily Maintenance Checklist Duplicate this page for routine use. For the week of: Maintenance Check Item Mon. Tues. Wed. Thurs. Check safety interlock operation. Check that the grass deflector is in the down position. Check brake operation. Check the engine oil level. Check the cooling system fluid level. Drain the water/fuel separator. Check the air cleaner. Check the radiator and screen for debris. Check unusual engine noises.1 Check the transmission oil level. Check the hydraulic hoses for damage.
Lubricating the Machine 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: All Models PTO shaft and yokes (3) (Fig. 33) Lift arm pivots (Fig. 33) Right and left push arm ball joints (Fig. 33) Figure 34 Push arm pivot bushings (Fig. 34) PTO pivot housing blocks (Fig. 35) Brake pivot bushings (Fig.
General Air Cleaner Maintenance • Check air cleaner body for damage which could possibly cause an air leak. Replace a damaged air cleaner body. • Service the air cleaner filters when air cleaner indicator (Fig. 41) shows red or every 400 hours (more frequently in extreme dusty or dirty conditions). Do not over service air filter. Figure 37 1 (2) (4) Figure 41 1. Air cleaner indicator • Be sure cover is sealing around air cleaner body. (2) Figure 38 Servicing Air Cleaner 1.
Note: This situation may be particularly prevalent if the rear discharge cutting unit is being used. The front of the radiator can be cleaned thoroughly by blowing with compressed air from the fan side of the radiator. Make sure to clean out any debris that settles to the bottom of the screen. The screen in front of radiator can be removed—by loosening wing nuts at top of screen—to make cleaning easier.
Servicing Fuel System Note: Refer to Fill Fuel Tank With Diesel Fuel for proper fuel recommendations. 1 Danger Under certain conditions, diesel fuel and fuel vapors are highly flammable and explosive. A fire or explosion from fuel can burn you and others and can cause property damage. 2 • Use a funnel and fill the fuel tank outdoors, in an open area, when the engine is off and is cold. Wipe up any fuel that spills. • Do not fill the fuel tank completely full.
Bleeding Air From Injectors 3. After the radiator is thoroughly cleaned, clean out debris that may have collected in the channel at the radiator base. Note: This procedure should be used only if fuel system has been purged of air through normal priming procedures and engine will not start; refer to Bleeding Fuel System. 4. Clean and install the screen. 1. Loosen the pipe connection to the No. 1 injector nozzle and holder assembly at injection pump (Fig. 48).
Cooling Fan Belt Level of coolant in expansion tank (Fig. 51) should be between the marks on side of tank. 1. Unlatch and open hood. 2. Remove capscrews (5) securing fan belt guard and remove guard (Fig. 53). 1 1 Figure 51 1. Expansion tank Servicing the Engine Belts Check tension of all belts initially after the first day of operation and every 100 hours thereafter. Alternator Belt 1. Unlatch and open hood. 2. Proper tension will allow 3/8 in. (10 mm) deflection when a force of 10 lbs.
Adjusting Traction Control Rod 5. Install fan belt guard and secure with capscrews (Fig. 53). Close and latch hood. 1. Check traction drive neutral position to assure front wheels do not creep; refer to Adjusting Traction Drive for Neutral. To replace belt: 1. Follow procedures in step 1 and 2 above. 2. 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. 56).
Adjusting Traction Pedal Friction Wheel wheel stops rotating, tighten capscrews holding pump plate against side of transmission. Verify the adjustment with throttle in SLOW and FAST position. 1. Loosen two nuts securing traction pedal shaft on right side of pedal (Fig. 57). 7. Block right front tire and both rear tires so vehicle cannot roll forward or backward. 2. Rotate shaft to relocate worn surface of friction wheel away from underside of traction pedal. 8.
Adjusting PTO Drive Belt Tension 4. Rotate adjusting screw until it contacts the switch button. Continue to rotate the screw until the circuit is completed (switch “clicks”). After the switch clicks, rotate the adjusting screw an additional 1/2 turn. Tighten jam nut. Important Check PTO belt tension initially after first 10 hours and 50 hours of operation and after every 100 hours of operation thereafter.
Adjusting the Parking Brake Interlock Switch 2 1 1. Gap between parking brake shaft pivot paddle and bottom of interlock switch (Fig. 61) should be approximately 1/16” (Paddle must not contact switch). 3 1 Figure 62 2 1. Pivot plate 2. Small nut 3. Large nut 3 2. Loosen small nut, rotate pivot bracket until it tightens large nut below (Fig. 62). Retighten small nut. 3. Reinstall steering column cover and parking brake knob. Figure 61 1. Parking brake interlock switch 2.
3. Loosen screw on tie rod clamp (Fig. 63). Rotate ball joint in or out to adjust length of tie rod. 4. Reinstall ball joint to mounting bracket and check wheel toe-in. 5. After attaining desired adjustment, tighten screw on tie rod clamp and re–secure ball joint to mounting bracket. Adjusting Rear Wheel Toe–in (Models 30626 & 30630 only) 5 The rear wheels should not toe–in or toe–out when they are adjusted correctly.
1. To reduce free travel of turn pedals—tighten the brakes—loosen front nut on threaded end of brake cable (Fig. 66). Then tighten rear nut to move cable backward until turn pedals have 1/2 to 1 in. (13 to 25 mm) of free travel. Tighten front nut after brakes are adjusted correctly. 1 Figure 67 1. Slot 6. Using a brake adjusting tool or screwdriver, rotate star nut (Fig. 67) down until brake drum (Fig. 68) locks because of outward pressure of brake shoes (Fig. 68). 1 2 Figure 66 1. Jam nuts 2.
Replacing the Hydraulic Fluid Filter Universal Tractor Hydraulic Fluid Mobil The hydraulic fluid filter keeps the hydraulic system relatively free of contaminants and must be serviced at regular intervals. Initially, change filter after first ten hours of engine operation, and thereafter, after every 200 hours of operation or yearly, whichever comes first. Use Toro oil filter, Part No. 23-9740, as a replacement. Amoco 1. Clean area where hydraulic fluid filter mounts. Remove filter from base (Fig.
8. Start and run the engine at idle speed for about two minutes and turn the steering wheel lock to lock to purge air trapped in the system. Shut the engine off. 9. Leave machine set for two additional minutes, then remove dipstick and check fluid level in axle (Fig. 71). If level is low, add fluid until level matches groove in dipstick (Fig. 71). If level is too high, remove drain plug (Fig. 70) and drain fluid until level matches groove in dipstick. 1 1 Figure 72 1 1.
Servicing the Battery 6. Add Mobil Fluid 424 until lubricant level is up to hole in clutch. Clutch should be approximately 1/3 full. 7. Install check plug. Warning Note: Do not use engine oil (i.e. 10W30) in bidirectional clutch. Anti–wear and extreme pressure additives will cause undesirable clutch performance. Battery posts, terminals, and related accessories contain lead and lead compounds, chemicals known to the State of California to cause cancer and reproductive harm. Wash hands after handling.
