Although Toro designs and produces safe products, you are responsible for operating the product properly and safely.
• the type of machine is unsuitable for its task; • Remember there is no such thing as a safe slope. Travel on grass slopes requires particular care. To guard against overturning: • lack of awareness of the effect of ground conditions, especially slopes; – do not stop or start suddenly when going up or downhill; • incorrect hitching and load distribution. • The owner/user can prevent and is responsible for accidents or injuries occurring to himself or herself, other people, or property.
• Disconnect battery and remove spark plug wire before making any repairs. Disconnect the negative terminal first and the positive last. Reconnect positive first and negative last. • Reduce the throttle setting during engine run-out and, if the engine is provided with a shut-off valve, turn the fuel off at the conclusion of mowing. • Keep hands and feet away from the cutting units. • Use care when checking the reels. Wear gloves and use caution when servicing them.
• If the engine must be running to perform a maintenance adjustment, keep hands, feet, clothing, and any parts of the body away from the cutting units, attachments, and any moving parts, especially the screen at the side of the engine. Keep everyone away. – Reduce speed when making sharp turns. Avoid sudden stops and starts. – When near or crossing roads, always yield the right-of-way. – Apply the service brakes when going downhill to keep forward speed slow and to maintain control of the machine.

2. Mount a washer and ball stud to each end of the front roller on the cutting units (Fig. 10). Be sure the basket lip is equidistant from the reel blades all across each reel. If the basket is too close to the reel, it is possible for the reel to contact the basket when the cutting unit is raised off of the ground. 6. Align the sockets in the ball joints so the open side of the socket is centered towards the ball stud. Tighten the jam nuts to secure the sockets in position (Fig. 12).
10. Coat the spline shaft of the motor with clean grease and install the motor by rotating the motor clockwise so that the motor flanges clear the studs. Rotate the motor counterclockwise until the flanges are encircling the studs. Tighten the mounting capscrews (Fig. 13). 3. Pour oil into the opening in the valve cover until the oil level is up to the Full mark on the dipstick. Add the oil slowly and check the level often during this process. Do not overfill.
Servicing the Hydraulic System Danger Recommended Hydraulic Fluid In certain conditions, gasoline is extremely flammable and highly explosive. A fire or explosion from gasoline can burn you and others and can damage property. The machine’s reservoir is filled at the factory with approximately 8.5 gallons (32.2 liters) of high quality hydraulic fluid. Check the level of hydraulic fluid before the engine is first started and daily thereafter. The appropriate hydraulic oils are listed below.
Mobil. Contact your Toro Distributor for details. The oil is available in 5 gallon (19 l) containers from your Toro Distributor, order part no. 100–7674. 2 Note: Use of this fluid requires installation of an Oil Cooler Kit, Part No. 105–8339, to the traction unit. This biodegradable fluid will break down quickly if the temperature exceeds 180°F (82°C).
Operation Ground speeds are as follows: Note: Determine the left and right side of the machine from the normal operating position. • 8.8 MPH (14.1 km/h) maximum transport speed • 2 to 5 MPH (3.2 to 8 km/h) forward mowing speed • 2.5 MPH (4 km/h) reverse speed Think Safety First Please carefully read all of the safety instructions and symbols in the safety section. Knowing this information could help you or bystanders avoid injury.
Ignition Switch Functional Control Lever Insert the key into the switch (Fig. 21) and turn it clockwise as far as possible to the Start position to start the engine. Release the key as soon as the engine starts; the key will move to the On position. Turn the key counterclockwise to the Off position to stop the engine. The functional control lever (Fig. 21) provides two traction selections plus a Neutral position.
Fuel Shut-Off Valve possible, open the choke by pulling it rearward to the Off position. A warm engine requires little or no choking. Close the fuel shut-off valve (Fig. 24), under fuel tank, when storing or transporting the machine on a truck or trailer. 5. Check the machine out with the following procedures after the engine has started: A. Move the throttle control to the Fast position and momentarily engage the reels by moving the raise/lower mow control lever forward.
Checking the Leak Detector The purpose of the safety interlock system is to prevent operation of the machine where there is possible injury to the operator or the machine. The leak detector system is designed to assist in early detection of hydraulic oil system leaks. If the oil level in the main hydraulic reservoir, is lowered by 4 to 6 ounces (118–177 ml), the float switch in the tank will close. After a one second delay, the alarm will sound, alerting the operator (Fig. 27).
4. Release the float. The alarm should stop sounding. 5. Install the strainer screen and hydraulic tank cap. Move the ignition switch to the Off position. Fluid Level (warm) Preparing the Machine for Mowing To assist in aligning the machine for successive cutting passes, it is suggested the following be done to the No. 2 and No. 3 cutting unit baskets: Warning Buzzer Float Down Switch Closed Fluid Level Down 4 to 6 ounces (118–177 ml) 1. Measure in approximately 5 in. (12.
Mowing Procedures procedure is important, so the mowers do not cut into the fringe area. However, as much of the green as possible should be cut to minimize the amount of grass left to mow around the outer periphery. 1. Approach the green with the functional control lever in the Mow position and the throttle at full speed. Start on one edge of the green so the ribbon procedure of cutting may be used. This holds compaction to a minimum and leaves a neat, attractive pattern on the greens. 5.
Leak Detector Operation Towing the Traction Unit The leak detector alarm may sound for one of the following reasons: In case of an emergency, the machine can be towed for a short distance (less than 1/4 mile [0.4 km]). However, we do not recommend this as a standard procedure. • A leak of 4 to 6 ounces (118–177 ml) has occurred. Important Do not tow the machine faster than 2–3 MPH (3–5 km/h) because the drive system may be damaged.
Maintenance Note: Determine the left and right side of the machine from the normal operating position. Recommended Maintenance Schedule Maintenance Service Interval Maintenance Procedure After first 8 hours • Change the engine oil. • Replace the engine oil filter. After first 50 hours • Replace the hydraulic oil filter. • Check the engine RPM (at idle and full throttle). Every 50 hours • • • • • Every 100 hours • Replace the engine oil filter. • Replace the air filter element.
Daily Maintenance Checklist Duplicate this page for routine use. For the week of: Maintenance Check Item Mon. Tues. Check the safety interlock operation. Check the instrument operation. Check the leak detector alarm. Check the brake operation. Check the fuel level. Check the engine oil level. Clean the engine air cooling fins. Inspect the air filter pre-cleaner.

Removing the Seat The seat may be removed to ease performing maintenance in the valve block area of the machine. 1. Unlatch and raise the seat. Secure with prop rod. 2. Disconnect the 2 wire harness connectors under the seat. 3. Lower the seat and remove the cotter pin securing the seat pivot rod to the frame (Fig. 40). 1 Figure 41 4. Slide the seat pivot rod to the left side, slide the seat forward, and lift the seat out. 1. ROPS support bracket 5. Reverse the procedure to install the seat.
Servicing the Air Cleaner 5. Install the foam element, paper element, and air cleaner cover. Service the air cleaner foam pre-cleaner after every 50 operating hours and the air cleaner cartridge after every 100 operating hours. More frequent cleaning is required when operating in dusty or dirty conditions. Important Do not operate the engine without the air cleaner element because extreme engine wear and damage will likely result. 1. Release the locking clips and remove the air cleaner cover (Fig. 43).
3. Pull firmly on the choke cable until the choke butterfly is completely closed, then tighten the cable clamp screw (Fig. 45). 4. Adjust the idle stop screw clockwise until the idle speed is an additional 25 to 50 RPM over the idle speed set in step 3. 5. Move the throttle control to the Fast position. Bend the high speed spring anchor tang (Fig. 46) to attain a high speed of 2850±50 RPM.
Replacing the Fuel Filter Changing the Hydraulic Oil and Filter An in-line filter is incorporated into the fuel line between the fuel tank and carburetor (Fig. 48). Replace the filter every 800 hours or sooner if the fuel flow is restricted. Be sure the arrow on the filter is pointing away from the fuel tank. Change the hydraulic oil after every 800 operating hours. If the oil becomes contaminated, contact your local Toro distributor because the system must be flushed.
Checking the Hydraulic Lines and Hoses 1 Warning 3 Hydraulic fluid escaping under pressure can penetrate skin and cause injury. • Make sure all hydraulic fluid hoses and lines are in good condition and all hydraulic connections and fittings are tight before applying pressure to the hydraulic system. • Keep your body and hands away from pin hole leaks or nozzles that eject high pressure hydraulic fluid. • Use cardboard or paper to find hydraulic leaks.
Adjusting the Transport Speed A. Loosen both jam nuts securing the traction control cable to the bulkhead on the hydrostat (Fig. 51). Make sure the jam nuts are loosened equally and sufficiently to allow adjustment. 5 1 Obtaining Maximum Transport Speed The traction pedal is adjusted for maximum transport speed at the factory, but an adjustment may be required if the pedal reaches full stroke before it contacts the pedal stop, or if a decrease in transport speed is desired.
Adjusting the Mowing Speed 1 The machine is adjusted at the factory, but speed may be varied if desired. 1. Loosen jam nut on pedal lock capscrew (Fig. 53). 1 Figure 54 1. Flow control valve Adjusting the Lift Cylinders Figure 53 To regulate the height of the front cutting units when in the raised (transport) position, the front lift cylinders may be adjusted. 1. Pedal lock capscrew 1. Lower the cutting units to the ground. 2.
Servicing the Fuses If corrosion occurs at the terminals, disconnect the cables, negative (–) cable first, and scrape the clamps and terminals separately. Reconnect the cables, positive (+) cable first, and coat the terminals with petroleum jelly. The fuses in the machine’s electrical system are located under the seat (Fig. 55). Warning Incorrect battery cable routing could damage the tractor and cables causing sparks. Sparks can cause the battery gasses to explode, resulting in personal injury.
5. While the engine is still warm, drain the oil from the crankcase. Refill it with fresh oil; refer to Changing the Engine Oil and Filter, page 30. 6. Remove the spark plugs, pour one ounce of SAE 30 oil into the cylinders, and crank slowly to distribute the oil. Replace the spark plugs; refer to Replacing the Spark Plugs, page 32. 7. Clean dirt and chaff from the cylinder, cylinder head fins, and blower housing. 8.
