The cooling system is filled with a 50/50 solution of water and permanent ethylene glycol anti-freeze. Check level of coolant at beginning of each day before starting the engine. Capacity of cooling system is approximately 6 quarts (5.7 L). 1. Carefully remove radiator cap.
CONTROLS Traction Pedal (Fig.16) Traction pedal has two functions; one is to make the machine move forward, the other is to make it move backward. 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).
CONTROLS 3 2 5 4 6 7 Ignition Switch (Fig. 18) - The key switch, which is used to start and stop the engine, has three position: OFF, RUN, and START. Rotate key clockwise to the START position to engage starter motor. When engine starts, release key and it will move automatically to the ON position. To shut engine off, rotate key counterclockwise to the OFF position. 8 1 11 Choke (Fig. 18) - To start a cold engine, close carburetor choke by moving choke control fully forward.

AIR CLEANER MAINTENANCE GENERAL MAINTENANCE PRACTICES Inspect air cleaner and hose periodically to maintain maximum engine protection and to ensure maximum service life. 1. Assure hose between air cleaner and carburetor is clamped securely in place. Replace the hose if it is cracked or punctured. 2. Check air cleaner body for dents and other damage which could possibly cause an air leak. Replace a damaged air cleaner body. 3. Be sure dust cap is sealing around bottom of air cleaner body. 2.
AIR CLEANER MAINTENANCE C. Dry filter element using warm, flowing air (160 F (71 C) max), or allow element to air-dry. Do not use compressed air or a light bulb to dry the filter element because damage could result. Compressed Air Method IMPORTANT: Do not remove plastic fin assembly because back-blowing with compressed air removes dust from beneath fins. A. Blow compressed air from inside to the outside of dry filter element. Do not exceed 100 psi (689 kPa) to prevent damage to the element. B.
ENGINE MAINTENANCE SERVICING ENGINE BELTS Check tension of all belts initially after the first day of operation and every 100 hours thereafter. Alternator Belt A new alternator belt (Fig. 33) is to be tensioned to 65 lbs. A used belt is to be tensioned to 40 lbs. 1. To adjust belt tension, loosen upper and lower nuts securing idler arm to front engine mount (Fig. 34). 2. Pull out on idler arm until desired belt tension is achieved. 3. Tighten mounting nuts to secure adjustment.
ENGINE MAINTENANCE ADJUSTING GOVERNOR 1. With engine shut off, move throttle control to FAST position and open hood. Check between the throttle arm and the stop on the carburetor base to make sure there is 1/32" (0.8 mm) gap (Fig. 35). If gap is not correct, adjust throttle rod (Fig. 35) by turning ball joint ends until gap is 1/32" (0.8 mm). If gap is correct, proceed to step 2. WARNING Engine must be running so final adjust ment of the governor can be performed.
ENGINE MAINTENANCE Note: If the throttle control on the instrument panel will not stay in the FAST position during operation, remove the panel cover and tighten the nut and capscrew at base of throttle lever assembly. CHECKING OIL LEVEL IN GOVERNOR 1 2 3 The governor is shipped with oil in it, but the level of oil must be checked after every 250 hours of operation. 1. Position machine on level surface and shut engine off. 2. Disengage hood latch and open the hood. 3.
TRACTION DRIVE MAINTENANCE ADJUSTING TRACTION CONTROL ROD ADJUSTING TRACTION PEDAL FRICTION WHEEL 1. Check traction drive neutral position to assure front wheels do not creep; refer to Adjusting Traction Drive for Neutral. 1. Loosen two nuts securing traction pedal shaft on right side of pedal (Fig. 39). 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. 38).
TRACTION DRIVE MAINTENANCE 7. Should front wheel continue to rotate, check for the following: A. Ball bearing is loose or worn out (Fig. 40). B. Plunger on interlock switch is sticking. C. Loose or missing fasteners. D. Worn roll pin securing pump lever to transmission. E. Pump lever loose on control shaft. (Correct by applying Loc-tite 271 or 601 to shaft.) F. Weak or damaged leaf springs (Fig. 40). Replace. G. Internal transmission component malfunction. Contact your local Toro distributor for assistance.
STEERING MAINTENANCE ADJUSTING TILT STEERING CONTROL If steering wheel tilt control lever must be adjusted, proceed as follows: 1. Remove knob from parking brake and self tapping screws from steering column cover. Slide cover up steering shaft to expose pivot bracket (Fig. 42). 2. Loosen small nut, rotate pivot bracket until it tightens large nut below (Fig. 42). Retighten small nut. 3. Reinstall steering column cover and parking brake knob. 1 Figure 43 1. Steering plate ADJUSTING REAR WHEEL BEARINGS 1.
BRAKE MAINTENANCE ADJUSTING BRAKES Adjust the service brakes when there is more than one inch (25 mm) of free travel" of the turn pedals, or when the brakes do not work effectively. Free travel is the distance the brake pedal moves before braking resistance is felt. The brakes should only need adjusting after considerable use. These periodic adjustments can be performed where the brake cables connect to the brake pedal mount.
HYDRAULIC SYSTEM MAINTENANCE ADJUSTING LIFT LEVER LATCH A lift lever latch that is positioned incorrectly can cause the lift lever to hold the spool in an actuated position when the implement is in the FLOAT position. This causes oil in the hydraulic system to overheat. When lift lever latch is adjusted correctly, the lift lever should just clear the rounded part of the latch as lever is moved into FLOAT position. 1 1. Unscrew ball from lift lever. 2.
HYDRAULIC SYSTEM MAINTENANCE Note: 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. The axle housing acts as the reservoir for the system. The transmission and axle housing are shipped from the factory with approximately 5 quarts (4.7 L) of SAE 10W 30 engine oil.
