BEFORE OPERATING Check The Engine Oil (Fig. 1 & 2) Crankcase capacity is 5 liters (5.3 qt) with filter. 1. Park the machine on a level surface. Release the hood latch and open the hood. 2. Remove the dipstick from the tube cap, wipe it clean and reinstall the dipstick into the tube cap. Pull it out again and check the oil level on the dipstick: The oil level must always be in the notch area on the dipstick. ➀ 3.
BEFORE OPERATING CAUTION Before servicing or making adjustments to the machine, stop the engine and remove the key from the switch 2. Remove the fuel tank cap. 3. Fill the tank to no more than one inch below the bottom of the filler neck with No. 2 diesel fuel. DO NOT OVER FILL. Then install the cap. ➀ Note: For temperatures below 0° C (32° F), No. 1 diesel fuel or a blend should be used. Figure 4 1. Fuel tank cap 4. Close the hood and secure the latch. Check The Hydraulic Circuit Oil (Fig.
BEFORE OPERATING (4–6 gal) of hydraulic oil. Order Part No. 44-2500 from your authorized Toro distributor 1. Park the machine on a level surface. Make sure the machine has been operated so the oil is warm. Release the hood latch and open the hood. Check the oil level by viewing the sight gauge. If oil is visible in the gauge, the oil level is sufficient. 2.
BEFORE OPERATING and wipe it with a clean cloth. Screw the dipstick cap finger tight onto the filler neck. Unscrew the dipstick and check the level of lubricant. If the level is not within 12 mm (1/2 in.) from the groove in the dipstick, add enough to raise the level to groove mark. DO NOT OVERFILL by more than 12 mm (1/2 inch) above the groove. ➀ 4. Screw the dipstick filler cap finger-tight onto the filler neck. It is not necessary to tighten the cap with a wrench.
BEFORE OPERATING Check The Torque Of Wheel Nuts Or Bolts WARNING Torque the front wheel nuts to 45–55 ft-lb and the rear wheel nuts or bolts to 85–100 ft lb after 1–4 hours of operation and again after 10 hours of operation and every 250 hours thereafter. Failure to maintain correct torque could result in failure or loss of the wheel and may result in personal injury. HEIGHT OF CUT—FRONT CASTOR WHEELS Check The Lubricant In The Gear Box (Fig.
BEFORE OPERATING Front Castor Wheels ❷ 1. Remove the lynch pin from the spindle shaft and slide the spindle out of the front castor arm. Slide spacers onto the spindle shaft to get the desired height-of-cut. ❸ 2. Push the castor spindle through the front the castor arm install remaining spacers onto the spindle and install the lynch pin to secure the assembly. ❶ Rear Castor Wheels Figure 10 1. Remove the hairpin cotter and H.O.C. pin securing the rear castor pivot arm to the deck bracket. 1. 2.
CONTROLS when the wing units are raised. Check to make sure the forward, lower edge of door is even or 6 mm (1/4 in.) higher then lower edge of door guide when wing decks are in the fully raised, transport position. If an adjustment to the door is required, refer to Adjusting The Safety Door. ❹ Cutting Unit Engagement Switch (Fig. 14)—Used to start and stop cutting unit operation. Lift switch and move forward to actuate the cutting unit.
CONTROLS allows 4 inch fore and aft adjustment. The seat adjusting knob on the front of the seat, adjusts the seat for operator’s weight. Traction Pedal (Fig. 16)—Controls forward and reverse operation. Depress the top of the pedal to move forward and the bottom to move backward. Ground speed depends on how far the pedal is depressed. For no load, maximum ground speed, fully depress the pedal while the throttle is in FAST.
CONTROLS Transport Latches (Fig. 18)—Four latches secure the cutting unit and wings in upright position for transport. ❶ Horn—In the center of steering wheel. Operates only when the key switch is in ON. Figure 18 1.
CONTROLS Starting And Stopping 1. Sit on the seat and keep your foot off the traction pedal. Assure the parking brake is engaged, the traction pedal is in NEUTRAL and the cutting unit engagement switch is in the DISENGAGED position. 2. Turn the ignition switch to ON. When the glow plug indicator light goes off, the engine is ready to START. 3. Turn the ignition key to START. Release the key when the engine starts. 4. To stop, disengage and move all controls to NEUTRAL and set the parking brake.
OPERATING INSTRUCTIONS Checking The Interlock System The purpose of the interlock system is to prevent the engine from cranking or starting unless the traction pedal is in NEUTRAL and the cutting unit engagement switch is DISENGAGED. Also, the engine will stop when the cutting unit engagement switch is engaged or the traction pedal is depressed with the operator off the seat. CAUTION The interlock switches are for the operator’s protection, so do not disconnect them.
OPERATING INSTRUCTIONS machine on a flat surface, engage the brakes and shift before climbing the slope. Be careful when driving between objects so you do not accidentally damage the machine or the cutting unit. Operating Characteristics Familiarization—Before mowing grass, practice operating the machine in an open area. Start and stop the engine. Operate in forward and reverse. When you feel familiar with the machine, practice operating around trees and obstacles.
OPERATING INSTRUCTIONS Always Mow With Sharp Blades—A sharp blade cuts cleanly and without tearing or shredding the grass blades. Tearing and shredding causes the grass to turn brown at the edges which impairs growth and increases susceptibility to diseases.
MAINTENANCE Greasing (Fig. 21–33) The traction and cutting units have grease fittings that must be lubricated regularly with No. 2 General Purpose Lithium Base Grease. If the machine is operated under normal conditions, lubricate all grease fittings after every 25 hours of operation. The grease fittings that must be lubricated are: Lift arm pivot (2), lift cylinder (2), brake arm pivots (2) (Fig. 21); brake pivot (1), brake pivots (2) (Fig. 22); traction pedal pivot (1) (Fig.

MAINTENANCE Adjusting The Traction Drive For Neutral (Fig. 34) The machine must not creep when the traction pedal is released. If it does creep, an adjustment is required. 1. Park the machine on a level surface, shut the engine off and move shift lever to HI. Depress only the left brake pedal and engage the parking brake. ❶ ❷ 2. Jack up the right side of the machine until the front tire is off the shop floor. Support -the machine with jack stands to prevent it from falling accidentally. Figure 34 1. 2.
MAINTENANCE 1. Loosen the jam nuts securing the ball joints to the threaded rod. 2. Rotate the threaded rod to raise or lower the edge of door until it is even or 6 mm (1/4 inch) higher than the lower edge of door guide when the wing decks are in the fully raised, transport position. CAUTION Check for proper operation of the safety doors each time the deck is cleaned and repair as needed.
