MAINTENANCE
PERIODIC CHECK
1. Regularly check all bolts and nuts for tightness.
2. If the belt begins to bottom out on the engine pulley, then replacement of the pulley is needed. This is
noticeable by the pulley “V” bottom becoming shiny.
BELT REPLACEMENT
The drive belt is located on the left side of the machine. To replace a worn or slipping belt proceed as fol-
lows.
1. Remove belt guard.
2. Make sure clutch lever is in disengaged position.
3. Start at the top of 9” or 7” pulley and begin removing belt in clockwise direction (facing tiller from the
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 9” or 7” pulley remove it from smaller pulley.
5. Replace belt by reversing sequence of steps above.
6. Replace belt guard, “C” nuts, and thumb screws.
LUBRICATION
1. Wheels -- Lubricate wheels and wheel support shafts once a month or every 40 operating hours with
#30 oil. Apply oil to axle and hub at back of wheel. Spin wheel to allow oil to move into bearing. In ex-
tremely dusty conditions, wheels may become tight because of dust in bearing area. When this occurs,
remove the wheels and clean axle and wheel bearing surfaces with solvent or emery cloth. Oil and reas-
semble.
2. Throttle Control Cable -- Lubricate control cable as necessary, with #30 oil. Apply with a saturated
rag or an oil can along the outer surface of the conduit. Remove excess oil.
3. Clutch Lever Pivots -- Apply a few drops of SAE 30 oil to the clutch hand lever and idler lever pivots
as required to maintain a free and smooth operation of clutch.
4. Transmission -- Fill transmission with machine in normal upright position. Fill plug is located on the
upper right hand side. Use 90 weight gear lube or 50 weight motor oil. Capacity is approximately 16
ounces. Remove fill plug. Remove check plug. Fill until check plug hole overflows. Replace plugs. If
excessive oil leakage appears around rotor shaft, the seals and shields must be replaced.
5. Idler Arm Pivots -- Lubricate idler arm pivots once a month or every 40 operating hours with #30 oil.
STORAGE --At the end of the season or if the tiller is to be stored for any length of time it should be
washed. To make the job easier use a soft-bristled scrub brush to clean wheels and tires. A stick can be
used to clean dirt from crevices. This simple procedure will keep your tiller looking like new for years.

5. Re-tighten 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 holding 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 spring 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.
