IMPORTANT: Do not allow oil or grease
to contact the pulleys, drive belt or
reverse disc. This can cause the belt or
disc to slip on the pulleys.
Lubricate the numberedareas in Figures
5-4 and 5-5, as follows:
1. Oil the wheelshaft betweenthe wheel
hubsand the transmission housing
(A, Figure5-4).
2. Oil all pivoting and connecting points
on the Wheels/Tines/PTODrive Leverand
the WheelSpeedLever (B, Figure5-4).
3. Greasethe face of the belt adjustment
block (C, Figure5-4).
4. Oil the DepthRegulator Lever,
including the spring inthe mounting
bracket(D, Figure5-4).
5. Oil the full length of the throttle cable
casing (E,Figure 5-4).
6. Oil threads on HandlebarHeight Adjust-
ment Lever(F, Figure 5-4).
Figure 5.4: Tiller lubrication points
(wheel removed for clarity).
7. Grease left- and right-side engine
mounting bars at the top, the middle, and
bottom (G,Figure 5-4).
8. Greasethe zerkgreasefitting located
on the pivot point atthe end of theWheel
Speed Lever(H, Figure 5-4). If Wheel
Speed Leverhas a greasefitting on pivot
assembly, apply2-to-3 strokes of multi-
purpose greaseat beginning and end of
tilling season.
9. Keepthe PTOaccessareawell-greased
(I, Figure5-5). If the Tines/PTOClutch
Leverbecomes hard to move, squirt some
oil into its accesshole, andwork it back
and forth to disperse the oil.

Oil Maintenance
Checking for Oil Leaks
At 25-hour operation intervals, checkthe
tiller for oil leaks. Inspect for oil accumu-
lations on thetiller or thefloor where it's
stored.
If tilling during very hot weather, the gear
oil may heatup and expand insidethe
transmissions. Toallow for this oil
expansion,both the power unit transmis-
sion and theLineattachment transmis-
sions haveoil relief vents (Figure 5-6).
Figure 5.6: Oil relief vent locations.
Thevents allow small amounts of oil to
seepout.
If a serious leakis discovered, please
contact your authorizeddealeror the
FactoryTechnicalService Departmentfor
serviceadvice.
A small amount of oil seepageor wetness
around a shaft opening or
cover is no causefor
alarm. But a heavy con-
centration of oil is more
serious. You should
tighten all bolts immedi-
ately,and replace any
worn sealsor gaskets.
Figure 5.5: Use grease liberally in PTO access area.
It may be impossible to
determine how much oil
hasbeen lost, so check the
oil levels in the PTOtrans-
mission and the tine
attachmentbefore using
thetiller again. Add any
necessarygear oil.
Seriousdamage to the
transmission components
canresult from operation
whengear oil levels are
low.
Checking Gear Oil Levels
Every30 hours of operation, checkthe
gearoil level in boththe power unit trans-
mission andthe tine attachment transmis-
sion. Operatingthem while low on gear
oil (evenbriefly) can cause serious
damageto internal components.
Preparation
I. The transmissionsmustbe cool,
since hot gear oil expandsand gives a
false reading.
2. The power unit transmission andthe
Lineattachmenttransmission must be
connectedwhen checking (or adding)
gearoil.
CheckingthePower Unit Oil Level
I. Move thetiller to level ground. Move
the Depth Regulatorup so thetines rest
on the ground.
2. Usea 3/8" wrench to removethe oil
levelcheck plug on the left side of the
transmission housing (Figure 5-7).
