This manual uses two other words to highlight information. Important calls attention to special mechanical information and Note: emphasizes general information worthy of special attention. Introduction Read this manual carefully to learn how to operate and maintain your product properly. The information in this manual can help you and others avoid injury and product damage. Although Toro designs and produces safe products, you are responsible for operating the product properly and safely.
• insufficient wheel grip; • Mow only in daylight or in good artificial light. • being driven too fast; • Before attempting to start the engine, disengage all blade attachment clutches, shift into neutral, and engage the parking brake. • inadequate braking; • the type of machine is unsuitable for its task; • Do not put hands or feet near or under rotating parts. Keep clear of the discharge opening at all times.
• Do not change the engine governor settings or overspeed the engine. Operating the engine at excessive speed may increase the hazard of personal injury. • Never store the equipment with fuel in the tank inside a building where fumes may reach an open flame or spark. • Before leaving the operator’s position: • Allow the engine to cool before storing in any enclosure.
• When a person or pet appears unexpectedly in or near the mowing area, stop mowing. Careless operation, combined with terrain angles, ricochets, or improperly positioned guards can lead to thrown object injuries. Do not resume mowing until the area is cleared. This product is capable of amputating hands and feet and throwing objects. Always follow all safety instructions to avoid serious injury or death.
Vibration Level Whole Body Hand-Arm This unit does not exceed a vibration level of .5 m/s at the posterior based on measurements of identical machines per ISO 2631 procedures. This unit does not exceed a vibration level of 2.5 m/s at the hands based on measurements of identical machines per ISO 5349 procedures.

1. Check level of coolant in expansion tank. Coolant level should be between the marks on side of tank. Before Operating Check Engine Oil The engine is shipped with 4 qt (3.8 l) of oil in the crankcase; however, level of oil must be checked before and after the engine is first started. 1 1. Park machine on a level surface, stop engine and remove key from ignition switch. Open hood. 2. Remove dipstick (Fig. 11), wipe clean and reinstall dipstick. Remove dipstick and check oil level.
Fill Fuel Tank 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. However, check level of transmission oil before engine is first started and daily thereafter. 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. 1.
left brake pedal so that it locks together with the right pedal. Next, push down fully on both pedals and pull parking brake knob out (Fig. 16) then release the pedals. To release parking brake, depress both pedals until parking brake knob retracts. Before starting the engine, however, lock arm may be disengaged from left brake pedal so both pedals work independently with each front wheel. Controls Service Brakes The left and right brake pedals (Fig. 16) are connected to the left and right front wheels.
Throttle After cutting unit is raised, allow lift lever to move to the TRANSPORT position. Cutting unit must be raised when driving from one work area to another. 1 3 2 4 Throttle (Fig. 19) is used to operate engine at various speeds. Moving throttle forward increases engine speed — FAST; rearward decreases engine speed — SLOW. The throttle controls the speed of the cutter blades and, in conjunction with traction pedal, controls ground speed of the traction unit.
Bleeding Fuel System Operation 1. Park the machine on a level surface. Make sure fuel tank is at least half full. Note: Determine the left and right sides of the machine from the normal operating position. 2. Unlatch and raise hood. Starting/Stopping Engine Danger Important The fuel system must be bled if any of the following situation have occurred. Under certain conditions, diesel fuel and fuel vapors are highly flammable and explosive.
Checking Interlock System To maintain enough power for the traction unit and cutting unit while mowing, 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 cutting blades increases; and increase ground speed as load on the blades decreases. This allows the engine, working with the transmission, to sense the proper ground speed while maintaining high blade tip speed necessary for good quality-of-cut.
considerable distance, transport it on a truck or trailer. Whenever traction unit is pushed or towed, by-pass valve must be open. Lubrication 1. Remove hair pin, pivot seat platform forward and locate seat support rod in detent notch. Greasing Bearings And Bushings 2. Depress and hold the pins located in the center of the two (2) check valve assemblies in the top of the transmission (Fig. 21) while pushing or towing the machine.

Maintenance Note: Determine the left and right sides of the machine from the normal operating position.
Caution 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 and disconnect the wire from the spark plug before you do any maintenance. Set the wire aside so that it does not accidentally contact the spark plug.

2. Gently slide filter (Fig. 30) out of air cleaner body to reduce the amount of dust dislodged. Avoid knocking filter against air cleaner body. Maintenance General Air Cleaner Maintenance 1. Check air cleaner body for damage which could possibly cause an air leak. Replace a damaged air cleaner body. 2. Service the air cleaner filter when air cleaner indicator (Fig. 28) shows red or every 400 hours (more frequently in extreme dusty or dirty conditions). Do not over service air filter. 1 1 Figure 30 1.
To thoroughly clean the radiator: 1. Remove the screen. 2. Working from the fan side of the radiator, either spray the radiator with a water hose or blow with compressed air. 1 3. After the radiator is thoroughly cleaned, clean out debris that may have collected in the channel at the radiator base. 4. Clean and install the screen. Figure 32 1. Oil filter Changing Engine Oil And Filter 6. After oil is drained, reinstall drain plug and wipe up any oil that is spilled.

Lubricate gasket on filter canister with clean oil. 3. Slide hose clamps onto ends of fuel lines. Push fuel lines onto fuel filter and secure them with hose clamps. Be sure arrow on side of filter points toward the injection pump. 4.
Alternator Belt PTO Belt 1. Condition and Tension – Check condition and tension of belts (Fig. 36) after every 100 operating hours. To Check Tension: 1. Turn engine off and remove the ignition key. Set the parking brake. Raise the engine hood and allow the engine to cool. A. Proper tension will allow 3/8 in. (10 mm) deflection when a force of 10 lbs. is applied on the belt midway between the pulleys. 2. Loosen the tensioning rod jam nut (Fig. 38). B. If deflection is not 3/8 in.
1. Turn engine off and remove the ignition key. Set the parking brake. Raise the engine hood and allow the engine to cool. 1. Park machine on a level surface and shut engine off. Depress only the right brake pedal and engage the parking brake. 2. Remove the left hand clutch retainer bracket nut and bolt so that the retainer bracket rubber bumper can be removed (Fig. 39). 2. Jack up left front side of machine until tire is off shop floor.
Changing Hydraulic Oil And Filter 1 2 Initially, replace the hydraulic system oil and filter after the first full day’s operation — NOT TO EXCEED 10 HOURS. Replace the oil and filter every 250 hours thereafter. The hydraulic system is designed to operate on any high quality detergent oil having the American Petroleum Institute — API — “service classification” SF/CC or CD. Oil viscosity — weight — must be selected according to anticipated ambient temperature for the season in which product will be used.
5. Install new hydraulic oil filter and connect the tube between axle housing and transmission. Fill axle (reservoir) to proper level (approx. 5 qt); refer to Check Hydraulic System Fluid. Remove jack stands. 1 1 6. Start engine, cycle steering and lift cylinders, and check for oil leaks. allow engine to run for about five minute. Then shut engine off. 7. After two minutes, check level of transmission fluid; refer to Check Hydraulic System Fluid. 3 1 Figure 44 1.
