A. ToCheckTransmission
1. Checkthe gear oil level when the trans-
mission is cool. Gearoil expands in warm
operating temperatures and will result in
an incorrect oil level reading.
2. Tocheckthe gear oil level (andto add
oil, if necessary), refer to STEP5."Check
GearOilLevel in Transmissionin Section2
of this manual.
D.To DrainandRefilltheTransmission:
Thetransmission gear oil doesnot needto
be changedunless it hasbeencontaminat-
ed with dirt, sand or metal particles.
1. Propupthe left sideofthe unit securely.
Removethe left-sidewheel by removing
the wheel mounting hardware.
2. Unscrewthe plastic gear oil fill plug
from the top ofthe transmission
3. Placea clean pan belowthe transmis-
sion drain plug (Figure5-4) and remove

7. Usea clean funnel to slowly add SAE
140 or SAE85W-140 weight gearoil (with
an API rating of GL-4 only) to the trans-
mission. Thetransmission holds approxi-
mately 3-1/4 pints (52-54 ounces).Tilt the
tiller slightly backwardsto make surethe
gear oil reachesthe rear (tine) end of the
transmission. Stop adding gearoil when it

EngineOil Service
Checkthe motor oil level before starting
the engineeachday andafter each5 hours
of continuous operation. Runningthe en-
gine whenthe oil level is low will quickly
ruin the engine.
It is recommendedthat you changethe

dirt from falling into the crankcase.
4. Onengines with an oil fill tube, remove
the filler cap andadd oil (if required) until
it reachesthe top of thetube. Reinstallthe
filler cap.
5. Onengines with a dipstick, removeit,
wipe it clean, and reinstall it finger4ight.
Removethe dipstick again and checkthe
reading. Add oil (if required) to bring the
level to the FULLmark. Do not overfill.

sistor spark plugsto suppress ignition sig-
nals. If the enginewas originally equipped
with a resistor spark plug, use the same
type for replacement.
