oil to transmission. Stop when
oil exits from check hole at the
side.
To top off the gear oil level in the transmission:
1. Follow steps 1 and 2 of “To Check the
Transmission Gear Oil Level” covered previously.
2. Unscrew the transmission oil filler cap (on top
of the transmission).
3. Use a funnel and pour either SAE 140, SAE
85W-140, or SAE 80W-90 weight gear oil with an
API rating of GL-4 or GL-5 into the transmission.
Don’t use multi-viscosity gear oil, automatic
transmission fluid, or engine oil in the
transmission. They are too light for transmission
use. They will

from the transmis­

5. Reinstall the

and tighten it se­
curely with the 3/8"
wrench.
6. Reinstall the transmission oil fill hole plug.
Securely tighten it by hand.
To drain and refill the transmission:
The transmission gear oil does not have to be
changed unless you know that it has been con­
taminated with dirt, sand or metal particles.
You will have to drain the transmission gear oil
if you are making repairs to the transmission.
1. Place a prop underneath the tiller so that it will
be supported when you remove the left-hand
wheel.
2. Remove the hardware securing the wheel to
the wheel shaft from the left-hand wheel. Slide
the wheel pin out of the holes in the wheel.
Remove the
wheel.
3. Position a
shallow pan
underneath the
transmission
gear oil drain
plug.
4. Unscrew the
transmission
gear oil fill plug
from atop the
transmission.
5. Use your

wrench to take out the transmission gear oil
drain plug from the left-hand side of the trans­
mission (beneath the left-hand axle shaft). Then
remove the transmission gear oil check hole plug
(on the left-hand side of the transmission above
the wheel axle shaft).
6. Allow all transmission oil to drain into the pan.
7. When the oil stops flowing, tilt the tiller forward
so oil will drain from the rear of the transmission.
8. After all the gear oil has drained, clean the
threads of the transmission drain plug, apply a
non-hardening gasket sealant to the plug’s
threads and reinstall the plug. Securely tighten it.
9. Insert a clean funnel in the transmission oil fill
hole. Slowly pour SAE 140 or SAE 85W-140
weight gear oil with an API rating of GL-4 only
into the transmission. The transmission holds ap­
proximately 3-1/4 pints (52-54 ounces). Slightly
tilt the tiller backwards to make sure the rear end
of the transmission gets filled with gear oil. When
gear oil begins to flow from the transmission
gear oil check hole, the transmission is full.
10. Reinstall the transmission gear oil check hole
plug. Securely tighten it with the 3/8" wrench.
11. Reinstall the transmission gear oil fill hole
plug. Tighten it securely by hand.
12. Reinstall the left-hand wheel. Remove prop.
CHECKING ENGINE OIL LEVEL
Keeping the engine oil level correct is very im­
portant. Running your engine when it is low on
oil is an invitation to expensive engine damage.
Check the engine oil level before using the
tiller. Also check it every five hours of operation.
If you are working in very dusty conditions, check
the oil level more frequently and change the oil
more often than the recommended intervals.
To check the engine oil level:
1. Move the tiller to a level area.
2. Move the Depth Regulator Lever to the sec­
ond notch (from the top). This puts the engine in
a level position.
3. Clean the area around either the engine dip­
stick or oil fill tube so no debris will fall into the
engine. If your engine has a fill tube, take off its
cap-the oil should be up to the top of the tube.
Add oil if needed, then replace the cap. If your
engine has a dipstick, remove it, wipe it clean,
and follow steps 4 through 6 next.
4. Screw the dipstick into the engine all the way.
Then tighten it finger-tight.
5. Unscrew dipstick. The oil level should be be­
tween FULL and ADD marks on the dipstick. Add
proper specification motor oil (see pages 48-49
or engine literature for motor oil specs) to bring
level to FULL mark. Do not overfill.
