General Information Filling the Fuel Tank DANGER Because gasoline is flammable, caution must be used when storing or handling it. Do not fill the fuel tank while engine is running, hot, or in an enclosed area. Va- pors may build up and be ignited by a spark or flame source many feet away.
Fuel Shut−off Valve The valve is located on the left front side of the engine. It has two positions: CLOSED and OPEN. Position valve to the closed position when storing or transporting the machine. Open valve before starting the engine. Figure 2 1.
Adjustments Throttle Control Adjustment If a new throttle cable must be installed or the cable is out of adjustment, adjust the cable as follows: 1. Park mower on a level surface. Make sure engine is OFF. Remove high tension lead from the spark plug. 2.
Adjusting V−belts To adjust belt tension on V−belts (Fig. 5), first check ad- justment of clutch control. Refer to Clutch Control in this section. If unable to attain the 7 to 9 lbs (31 to 40 N) of force that is required in adjusting the clutch control, pro- ceed to the next step.
Service and Repairs Engine Oil The TORO Company recommends that the oil level be Changing the Oil: checked each time the mower is used or after every 5 1. Start and run engine for a few minutes to warm the operating hours.
Air Cleaner Normally, clean air filter precleaner (foam element) after every 25 operating hours and the air cleaner filter (paper element) after every 100 operating hours. More frequent cleaning is required when the mower is operated in dusty or dirty conditions. Replace air cleaner filter (pa- per element) after 200 operating hours.
Page 29
Removal 1. Make sure machine is parked on a level surface with the engine OFF. Remove high tension lead from the spark plug to prevent the engine from starting. Close fuel shut−off valve. 2. Remove pulley V−belts (Fig. 12). A. Make sure clutch is DISENGAGED so the V− belts (34) are slackened.
Page 30
Reinstalling the Engine 1. Make sure machine is parked on a level surface. The machine may be placed on a large work bench to make engine installation and adjustment easier. Re- move high tension lead from the spark plug. 2. Make sure that all parts removed from the engine INSIDE FACE during maintenance or rebuilding are properly rein- stalled to the engine.
Lubrication Both fittings on the bellcrank assembly should be greased at least every 25 hours. Lubricate using No. 2 multipurpose lithium base grease. A hand operated grease gun is recommended for best results. 1. Park mower on a level surface. Make sure engine is OFF.

Multimeter The meter can test electrical components and circuits for current, resistance, or voltage. NOTE: Toro recommends the use of a DIGITAL Volt− Ohm−Amp multimeter when testing electrical circuits. The high impedance (internal resistance) of a digital me- ter in the voltage mode will make sure that excess cur- rent is not allowed through the meter.

Ignition System Operation Making a System Tester This simple tester can be made if a commercial spark tester is not available. It can determine if the ignition sys- tem is operating properly. SPRING CLIP Note: This tester is not necessary if spark tester TOR4036 (see Special Tools in this chapter) is avail- able.

Igniter (Kawasaki Engine on Machine with Serial Number Below 60465) The igniter consists of transistorized circuitry that con- trols the firing sequence of the spark plug in conjunction with the ignition coil. Mounted on the engine block, the igniter casing is grounded directly to the engine. A single black wire makes a circuit from the igniter to the primary of the ignition coil.
Ignition Coil (Kawasaki Engine) A commercial coil tester can be used to test the ignition coil. If a tester is available, test the ignition coil as sug- gested in the Kawasaki FE161 & FE170 Service Manual and Kawasaki FE120 Service Manual Sup- plement The coil can be tested for a badly shorted or broken winding with a digital ohmmeter.
Ignition Coil (Subaru Engine) The coil can be tested for a badly shorted or broken winding with a digital ohmmeter. However, an ohmmeter can not detect layer shorts and shorts resulting from in- sulation breakdown under high running voltages. Note: Prior to taking small resistance readings with a digital multimeter, short the test leads together.

General Information Operator’s Manual The Cutting Unit Operator’s Manual provides informa- tion regarding the operation, general maintenance and maintenance intervals for the cutting unit on your Greensmaster machine. Additionally, if optional kits have been installed on the cutting unit (e.g. grooming reel), the installation instructions for the kit includes set−...
Special Tools Order special tools from your Toro Distributor. Some tools may have been supplied with your mower or avail- able as TORO parts. Some tools may also be available from a local supplier. Gauge Bar Assembly − P/N 13−8199 Used to verify height−of−cut.

This tool should be used with the Toro Guide to Evaluation Reel Mower Performance and Using the Turf Evaluator (Toro part no. 97931SL).
Because the top grind angle on bedknives is critical for edge retention, and therefore after− cut appearance, Toro has developed these service tools for accurately measuring the top grind angle on all bedknives. Since there can be variations in the mounting surface of the bedbar, it is necessary to grind the bedknife after installing it to the bedbar.
Troubleshooting There are a number of factors that can contribute to un- mower. It is important to remember that the lower the satisfactory quality of cut, some of which may be turf height−of−cut, the more critical these factors are. See conditions.
Page 129
Factor Possible Problem/Correction Height−of−cut “Effective” or actual height−of−cut depends on the mower weight and turf conditions. Effective height−of−cut will be different than the bench set height−of−cut. Proper bedknife for height−of−cut If the bedknife is too thick for effective height−of−cut, poor quality of cut will result. Front roller scraper and comb adjustment Install and/or adjust roller scrapers if grass clippings build up on the rollers.
Adjustments CAUTION Never work on the mower with the engine running. Always stop the engine and re- move the high tension lead from the spark plug first. Leveling Drum to Reel 1. Make sure engine is OFF. Remove high tension lead from the spark plug.
(8 kg−cm) be evident, it will be either necessary to backlap or regrind the reel and bedknife to achieve the sharp edges needed for precision cutting (see Toro General Service Training Book, Reel Mower Figure 15 Basics (part no. 09168SL).
Height−of−Cut Adjustment 1. Park mower on a level surface. Make sure engine is OFF. Remove high tension lead from the spark plug. 2. Verify that the drum is level to the reel and that the bedknife to reel contact is correct. Tip mower back on its handle to expose roller, drum, and bedknife.
Grass Shield Height Adjustment Adjust shield to assure proper grass clipping discharge into the basket. 1. Park mower on a level surface. Make sure engine is OFF. Remove high tension lead from the spark plug. 2. Measure distance from the top of the front support rod to the front lip of the shield at each end of cutting unit (Fig.
4. Insert a 1/2−inch socket extension, which is con- nected to a backlapping machine, into the square hole in the center of the reel pulley. 5. Backlap according to procedure in Toro General Service Training Book, Reel Mower Basics (part no. 09168SL).
Bedbar Removal 1. Position mower on a flat level work surface. Make sure engine is OFF. Remove high tension lead from the spark plug. 2. Loosen jam nut on the adjusting screw. Loosen ad- justing screw until the thrust washer contacts the inside of the frame adjuster.
