Safety Instructions
The GREENSMASTER 1000 was tested and certified
by TORO for compliance with the B71.4–1984 specifica-
tions of the American National Standards Institute. Al-
though hazard control and accident prevention partially
are dependent upon the design and configuration of the
machine, these factors are also dependent upon the
awareness, concern, and proper training of the person-
nel involved in the operation, transport, maintenance,
and storage of the machine. Improper use or mainte-
nance of the machine can result in injury or death.

4. 10. Check the safety interlock switch daily for proper op- operating machine. (After every two years, replace the
eration; see Component Testing in Chapter 5 – Electri- interlock switch in the safety system, whether it is work-
cal System. Replace malfunctioning switches before ing properly or not.)
While Operating
11. Do not run the engine in a confined area without ad-
equate ventilation. Exhaust fumes are hazardous and
could be deadly.
12. Always stand behind the handles when starting and
operating the machine.
13. To start and stop the engine:
A. Open fuel shut-off valve.
B. Verify that the traction drive lever on handle is in
NEUTRAL position and reel drive lever on mower is
DISENGAGED.
C. Move on/off switch to ON position, set choke to
full choke position (cold start) and throttle to half
throttle.
D. Pull starter cord to start engine.
E. Move throttle to SLOW and on/off switch to OFF
position to stop engine.
14. To transport mower from one area to another:
A. Install transport wheels.
B. Disengage reel drive lever.
C. Start engine.
D. Press down on handle to raise front of mower
and engage traction drive.
15. Before beginning mowing operation:
A. Stop engine.
B. Disengage traction drive.
C. Remove transport wheels.
D. Engage reel drive lever.
16. Before emptying basket of clippings, disengage
traction drive, reduce engine speed and move on/off
switch to off position.
17. Do not touch engine, muffler or exhaust pipe while
engine is running or soon after it has stopped because

keep all nuts, bolts, screws and belts properly tightened.
22. If major repairs are ever needed or assistance is re-
quired, contact an Authorized TORO Distributor.
23. To reduce potential fire hazard, keep the engine
area free of excessive grease, grass, leaves and accu-
mulation of dirt.
24. If the engine must be running to perform a mainte-
nance adjustment, keep hands, feet, clothing, and any
parts of the body away from the cutting unit and any
moving parts. Keep everyone away.
25. Do not overspeed the engine by changing governor
settings. Maximum engine speed is 3600 rpm. To as-
sure safety and accuracy, have an Authorized Toro Dis-
tributor check maximum engine speed with a
tachometer.

9. Introduction
This Chapter gives information about specifications,
maintenance, troubleshooting, testing, and repair of the
gasoline engine used in the Greensmaster 1000/1600
mower.
Most repairs and adjustments require tools which are
commonly available in many service shops. Special
tools are described in the Kawasaki FE161 & FE170
Service Manual and Kawasaki FE120 Service Manual
Supplement. The use of some specialized test equip-
ment is explained. However, the cost of the test equip-
ment and the specialized nature of some repairs may
dictate that the work be done at an engine repair facility.
Service and repair parts for Kawasaki engines are sup-
plied through your local Toro distributor. If no parts list is
available, be sure to provide your distributor with the
Toro model and serial number.

1. Park mower on a level surface. Make sure engine
is OFF.
2. Clean around fuel tank cap and remove cap from
tank (Fig. 1). Using unleaded gasoline, fill fuel tank to
bottom of filter screen. DO NOT OVER FILL.

14. 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. Move throttle lever to the SLOW position.
3. Loosen throttle cable screw securing the throttle
cable to the governor lever.
Note: Engine speed is measured at the input drive
pulley (Fig. 6). Actual engine speed is twice the input
drive pulley speed.
4. The governor lever will move to the slow idle posi-
tion if it is improperly adjusted.
A. Check low idle speed setting with a tachometer.
Low idle speed should be 750 to 850 rpm. Adjust
low speed idle screw in or out to attain the correct
speed setting.
B. Check high idle speed setting with a tachometer.
High idle speed should be 1750 to 1850 rpm. Ad-
just high speed idle screw in or out to attain the cor-
rect speed setting.

the governor lever is against the low speed idle screw.
6. Tighten throttle cable screw securing the throttle
cable to the governor lever.
Clutch Control Adjustment
If clutch control does not engage or it slips during opera-
tion, an adjustment is required.
1. Park mower on a level surface. Make sure engine
is OFF. Remove high tension lead from the spark plug.
2. Move traction control to DISENGAGED position.
3. Loosen retainer securing V–belt cover and pivot
cover open.
4. To increase cable tension, loosen front cable jam
nut and tighten back cable jam nut (Fig. 3) until a force
of 7 to 9 lbs (31 to 40 N) is required to engage clutch con-
trol. The force should be measured at the control knob.

15. 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.
1. Park mower on a level surface. Make sure engine
is OFF. Remove high tension lead from the spark plug.
2. Loosen retainer securing the V–belt cover and pivot
cover open.
3. To increase V–belt tension, loosen cap screws se-
curing the engine to the engine base (Fig. 12). Move en-
gine backwards in slots. DO NOT OVER TENSION
BELTS. Tighten cap screws. Figure 5

4. Check that a force of 7 to 9 lbs (31 to 40 N) is re-
quired to engage the clutch control. Adjust engine in
slots as necessary to get required tension on V–belts.
5. After tensioning V–belts, check alignment of the in-
put drive pulley and input shaft pulley with a straight
edge.
A. Inside pulley faces should be flush to each other
to within 0.030 inch (0.762 mm) maximum (Fig. 6).
B. If pulleys are misaligned, loosen cap screws se
-
curing the engine mounting base to the mower
frame. Slide engine from side to side until the pul
-
leys are aligned (Fig. 7).
6. Tighten cap screws and recheck alignment.
