ADJUSTMENTS and MAINTENANCE
CLUTCH ADJUSTMENT (Figure 7)
Proper clutch adjustment is very important. Minor adjust-
ment, if needed, can be made by using the links on the
clutch cable chain only. However, the friction type clutch
may need further adjustments as the “V” belt stretches. Ad-
just as follows:
1. Remove belt guard.
2. Loosen 4 engine mount bolts. Slide engine forward or
backwards as required.
3. Unhook clutch cable from load spring.
4. Push upward on idler pulley to take all slack from the
drive belt. Distance between the inside of belt at the idler
pulley should be between 2 7/8 and 3 1/8 of an inch.
5. Retighten engine mounting bolts.
6. Remove all the slack from clutch cable and hook spring
in proper chain link.
7. Check your adjustment by starting the tiller and hold-
ing the tines off the ground. If the tines turn without any
hand pressure on the clutch lever, the adjustment is too
tight. Unhook the clutch load and hook into next chain link
to lengthen clutch cable. If the cable spring on the clutch
handle doesn’t stretch when you hold the clutch handle all
the way in, the adjustment is too loose. Unhook spring end
from chain and hook next link to shorten clutch cable.
CHECK TRANSMISSION OIL
Check transmission oil by removing oil level check plug
(See Figure 8). If you cannot see oil from the check plug.
Refit plug and add 90 weight gear oil from the oil fill plug.
Do not overfill. This will cause leakage. Recheck level. Oil
should just ooze from Oil level check plug.
CLEAN COOLING SYSTEM (Figure 9)
Grass or chaff may clog cooling system after prolonged
service. Continued operation with a clogged cooling sys-
tem causes severe overheating and possible engine dam-

age. Remove blower housing and clean regularly.
BELT REPLACEMENT
The drive belt is located on the left side of the machine. To replace a worn or slipping belt proceed as follows:
1. Remove belt guard.
2. Make sure clutch lever is in disengaged position.
3. Start at the top of 10” pulley and begin removing belt in clockwise direction (facing tiller from left side). If tension on
belt is too great the idler pulley may be pulled downward to relieve pressure on belt.
4. Once belt is off 10” pulley, remove it from smaller pulley.
5. Replace belt by reversing sequence of steps above.
6. Replace belt guard, “C” nuts, and thumb screws.
DANGER
To avoid possible serious bodily injury, when performing any adjustments other than carburetor
adjustment on engine, remove the spark plug wire and place the wire away from the plug to prevent
accidental starting.
