Figure 5 Remove the key from the ignition before you do any maintenance. 1. Dipstick 4. If the oil is below the Full mark, remove the fill cap (Figure 6) and add oil until the level reaches the Full mark. Do not overfill.
Use of summer grade fuel above 20° F (-7° C) will contribute toward longer fuel pump life and increased power compared to winter grade fuel. If the engine has been running, the pressurized, hot coolant can escape and cause burns. Important: Do not use kerosene or gasoline instead of diesel fuel. Failure to observe this caution will damage the engine. • Do not open the radiator cap when the engine is running. • Use a rag when opening the radiator cap, and open the cap slowly to allow steam to escape.
2. Using a clean rag, clean area around fuel tank cap. 3. Remove cap from the fuel tank (Figure 8). In certain conditions, fuel is extremely flammable and highly explosive. A fire or explosion from fuel can burn you and others and can damage property. • Fill the fuel tank outdoors, in an open area, when the engine is cold. Wipe up any fuel that spills. • Never fill the fuel tank inside an enclosed trailer.

Viscosity Index ASTM D2270 Pour Point, ASTM D97 Service Interval: Every 400 hours 140 to 160 Check the oil level after every 400 hours of operation or if external leakage is noted. Use high quality SAE 85W-140 gear lube as a replacement.
3. Add gear oil to the hole in the planetary, if necessary, to bring the oil up to the proper level. Install the plug. 4. Repeat steps 1-3 on the opposite gear assembly. Checking the Rear Axle Lubricant Service Interval: Every 400 hours The rear axle is filled with SAE 85W-140 gear lube. Check the oil level before the engine is first started and every 400 hours thereafter. The capacity is 80 oz (2.4 l). Visually inspect for leaks daily. Figure 13 1. Position the machine on a level surface. 1.
castor forks, add or remove an equal number of spacers from the castor forks, and secure the rear chain to the desired hole. below) onto the spindle shaft to get the desired height-of-cut; then slide the washer onto the shaft. Refer to the following chart to determine the combinations of spacers for the setting: 1. Start the engine and raise the cutting units so that the height-of-cut can be changed. Stop the engine and remove the key after the cutting unit is raised. 2.
Figure 17 Note: When using 1 inch (25 mm), 1-1/2 inch (38 mm), or occasionally 2 inch (51 mm) height-of-cut, move the skids and gage wheels to the highest position. Wing Cutting Units To adjust the height-of-cut on the side cutting units, add or remove an equal number of spacers from the castor forks, position the castor wheel axles in the high or low height-of-cut holes in the castor forks, and secure the pivot arms to the selected height-of-cut bracket holes. Figure 18 1. Castor wheel 2.
6. Insert the clevis pins and install the hairpin cotters. 7. Rotate tension rod counterclockwise (finger tight) to put tension on adjustment. Figure 22 1. Skid Adjusting the Cutting Unit Rollers The cutting unit rollers should be mounted in the lower position when operating in height of cuts greater than 2-1/2 inches (64 mm) and in the higher position when operating in height of cuts lower than 2-1/2 inches (64 mm). 1.
7. If cutting unit adjustments are still needed, find a flat surface using a 6 foot (2 m) or longer straight edge. 8. To ease measuring blade plane, raise the height of cut to the highest position; refer to Adjusting the Height of Cut. 9. Lower cutting units onto the flat surface. Remove the covers from the top of the cutting units. Figure 24 10. Loosen the flange nut, securing the idler pulley, to release the belt tension on each cutting unit. 3.
4. When the glow indicator dims, turn the ignition key to the Start position. Release the key immediately when the engine starts and allow it to return to the Run position. Allow engine to warm up at mid speed (without load), then move the throttle control to the desired position. Important: Do not run the starter motor more than 15 seconds at a time or premature starter failure may result.
Checking the Interlock Switches • Raise either wing cutting unit to the transport position. The cutting unit should turn off. If the cutting unit does not stop, there is a malfunction in the interlock system that should be corrected before resuming operation. • If the cutting unit is lowered again the motor should re-start. If the cutting unit does not re-start, there is a malfunction in the interlock system that should be corrected before resuming operation.
Note: Resistance will be felt on the valve when it is moved to the open position. 3. Rotate the valve 90 degrees (1/4 turn) back to close the bypass valve before starting the engine. However, do not exceed 5 to 8 ft-lb (7 to 11 N⋅m) torque to close the valve. Figure 30 1. Reverse four-wheel drive pressure test port Jacking Points There are jacking points located at the front and rear of the machine. • On the frame at the inside of each front drive tire • At the center of the rear axle Figure 28 1.
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 brakes is to maintain traction. For example, in some slope conditions, the uphill wheel slips and loses traction. If this situation occurs, depress the uphill turn pedal gradually and intermittently until the uphill wheel stops slipping, thus, increasing traction on the downhill wheel.
Figure 32 1. Deck lift cylinder 2. Foam deck pad Cutting Unit Pitch We recommend a blade pitch of 1/4 inch (6 mm). A pitch larger than 1/4 inch (6 mm) will result in less power required, larger clippings, and a poorer quality of cut. A pitch less than 1/4 inch (6 mm) will result in more power required, smaller clippings and a better quality of cut.
Maintenance Note: Determine the left and right sides of the machine from the normal operating position. Recommended Maintenance Schedule(s) Maintenance Service Interval Maintenance Procedure After the first 10 hours • Torque the wheel lug nuts. • Check the fan belt tension. • Check the blade drive belt tension. After the first 50 hours • Change the engine oil and filter. • Check the engine speed (at idle and full throttle).
If you leave the key in the ignition switch, someone could accidently start the engine and seriously injure you or other bystanders. Remove the key from the ignition before you do any maintenance. Service Interval Chart Figure 33 Lubrication The sealed bearings require no lubrication or short term maintenance. This minimizes routine service required and reduces the potential of turf damage due to grease contamination.

Engine Maintenance Air Cleaner Maintenance • 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. • Service the air cleaner filter only when the service indicator requires it or every 400 hours (more frequently in extremely dusty or dirty conditions). Changing the air filter before it is necessary only increases the chance of dirt entering the engine when the filter is removed.
Important: Never attempt to clean the safety filter (Figure 49). Replace the safety filter with a new one after every three primary filter services. 2. Remove the oil filter (Figure 51). Apply a light coat of clean oil to the new filter seal before screwing it on. Do not overtighten. Figure 49 1. Air cleaner safety filter Figure 51 1. Engine oil filter 4. Clean the dirt ejection port located in the removable cover.
Fuel System Maintenance 2. Loosen the drain plug on the bottom of the filter canister. Servicing the Fuel System 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. Figure 52 • 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. 1.
Electrical System Maintenance connector. Turn the key to the Off position when solid flow is observed. 4. Tighten the tube connector securely. 5. Repeat the procedure on the remaining nozzles. Battery Care Battery type is group 24. Important: Before welding on the machine, disconnect the negative cable from the battery to prevent damage to the electrical system. Note: Check the battery condition weekly or after every 50 hours of operation.
Battery terminals or metal tools could short against metal components causing sparks. Sparks can cause the battery gasses to explode, resulting in personal injury. • When removing or installing the battery, do not allow the battery terminals to touch any metal parts of the machine. • Do not allow metal tools to short between the battery terminals and metal parts of the machine. Incorrect battery cable routing could damage the machine and cables causing sparks.
Drive System Maintenance Changing the Planetary Gear Drive Oil Service Interval: After the first 200 hours Every 800 hours Change the oil initially after first 200 hours of operation. Thereafter change the oil every 800 hours, or yearly, whichever occurs first. Use a high quality SAE 85W-140 gear lube. 1. With the machine on a level surface, position the wheel so that the check/drain plug (Figure 58) is at the lowest position. Figure 56 1. Fuses Figure 57 1. 2. 3. 4.
level is up to the bottom of the planetary and brake housing check holes. Capacity is approximately 16 oz. (0.5 l). 9. Install the plugs. 10. Repeat the procedure on the opposite gear assembly. Figure 60 1. Drain plug location 5. Clean the area around the drain plug on the bottom of the gear box (Figure 61). 6. Remove the drain plug from the gear box and allow the oil to drain into a pan. Remove the fill plug to ease in draining of the oil. Figure 59 1. Brake housing 2. Drain plug 3.
Checking the Rear Wheel Toe-In Cooling System Maintenance Service Interval: Every 800 hours After every 800 operating hours or annually, check the rear wheel toe-in. Servicing the Engine Cooling System 1. Measure the center-to-center distance (at axle height) at the front and rear of the steering tires. The front measurement must be 1/4 inch (6 mm) less than the rear measurement. Remove debris from the oil cooler and radiator daily. Clean them more frequently in dirty conditions.
Brake Maintenance Adjusting the Service Brakes Adjust the service brakes when there is more than 1 inch (25 mm) of “free travel” of the brake pedal, or when the brakes do not work effectively. Free travel is the distance the brake pedal moves before braking resistance is felt. 1. Disengage the locking latch from the brake pedals so that both pedals work independently of each other. 2. To reduce free travel of the brake pedals, tighten the brakes: Figure 63 1. Oil cooler A.
Belt Maintenance Note: Make sure the belt is positioned on the spring side of the belt guide (Figure 65). Servicing the Alternator Belt Service Interval: After the first 10 hours Every 100 hours Check the condition and tension of the belts (Figure 64) after every 100 operating hours. 1. Proper tension will allow 3/8 inch (10 mm) deflection when a force of 10 lb is applied on the belt midway between the pulleys. 2. If the deflection is not 3/8 inch (10 mm), loosen the alternator mounting bolts (Figure 64).
Controls System Maintenance Adjusting the Throttle Cable Service Interval: After the first 50 hours Every 400 hours Adjust the throttle cable (Figure 67) so that the governor lever on the engine contacts the low and high speed set bolts before the throttle lever contacts the slot in the control panel. Figure 66 1. Hydraulic motor 2. Mounting bolts 5. Remove the old belt from around the spindle pulleys and idler pulley. 6. Route the new belt around the spindle pulleys and idler pulley assembly. 7.
Hydraulic System Maintenance Changing the Hydraulic Fluid Service Interval: After the first 200 hours Every 800 hours Figure 68 1. Traction pedal stop Change the hydraulic fluid after every 800 operating hours, in normal conditions. If the fluid becomes contaminated, contact your local Toro distributor because the system must be flushed. Contaminated fluid looks milky or black when compared to clean oil. 1. Turn the engine off and raise the hood. 2.
Replacing the Hydraulic Filters deterioration. Make all necessary repairs before operating. Service Interval: After the first 200 hours Every 800 hours Change the 2 hydraulic filters initially after the first 200 operating hours. Thereafter, change the filters after every 800 operating hours, in normal conditions. Hydraulic fluid escaping under pressure can penetrate skin and cause injury.
Mower Maintenance Adjusting the Cutting Unit Flow Control Pivoting (Tilting) the Front Cutting Unit Upright The flow control valve (Figure 72) is used to adjust the rate at which the cutting unit lowers. Note: Although not needed for normal maintenance procedures, the front cutting unit can be pivoted (tilted) to an upright position. Should you desire to tilt the cutting unit, proceed as follows: 1.
Pivoting the Front Cutting Unit Down 1. Slowly lower wing cutting units until the center of gravity shifts and the center cutting unit rotates downward. 2. Sit on the seat, start the engine, and lower the center cutting unit until it is slightly off of the floor. 3. Secure the height-of-cut chains to the rear of the cutting unit. Figure 75 4. Pivot dampers upward into position and secure with clevis pin and cotter pin. 1. Height-of-cut chain Adjusting the Cutting Unit Pitch 2.
Servicing the Castor Arm Bushings or the castor pivot arm (Figure 79). Grasp the castor wheel and slide the bolt out of the fork or pivot arm. The castor arms have bushings pressed into the top and bottom of the tube and after many hours of operation, the bushings will wear. To check the bushings, move the castor fork back and forth and from side to side. If the castor spindle is loose inside the bushings, the bushings are worn and must be replaced. 1.
Blade Maintenance Replacing the Cutting Unit Hinge Covers Checking for a Bent Blade The hinge cover prevents debris from escaping at hinge points between cutting units. If cover(s) ever become damaged or worm they must be replaced. 1. Position the machine on a level surface. Raise the cutting unit, engage the parking brake, put the traction pedal in neutral, put the PTO lever in the Off position, stop the engine, and remove the ignition key.
wears down, the quality-of-cut will degrade somewhat, although the cutting edges are sharp. The cutting edge of the blade must be sharp so that the grass is cut rather than torn. A dull cutting edge is evident when the tips of the grass appear brown and shredded. Sharpen the cutting edges to correct this condition. 2. Grasp the end of the blade using a rag or thickly padded glove. Remove the blade bolt, anti-scalp cup, and blade from the spindle shaft (Figure 82). 3.
If the blade is allowed to wear, a slot will form between the sail and flat part of the blade (Figure 83). Eventually a piece of the blade may break off and be thrown from under the housing, possibly resulting in serious injury to you or bystanders. • Inspect the blade periodically for wear or damage. • Never try to straighten a blade that is bent or weld a broken or cracked blade. • Replace a worn or damaged blade. Figure 84 1.
Spark Arrestor Maintenance the dimensions must not exceed 1/8 inch (3 mm). If the dimension exceeds 1/8 inch (3 mm), replace the blade because it is bent. Make sure to measure all of the blades. 6. Compare the measurements of the outer blades with the center blade. The center blade must not be more than 3/8 inch (10 mm) lower than the outer blades.
Storage Preparing for Seasonal Storage Traction Unit 1. Thoroughly clean the traction unit, cutting units, and the engine. 2. Check the tire pressure; refer to Checking the Tire Pressure procedure in , page . 3. Check all fasteners for looseness; tighten as necessary. 4. Grease or oil all grease fittings and pivot points. Wipe up any excess lubricant. 5. Lightly sand and use touch-up paint on painted areas that are scratched, chipped, or rusted. Repair any dents in the metal body. 6.
