MAINTENANCE AND SERVICE
amounts of oil to seep out, thus
relieving any excess pressure in­
side the transmission. You should
not be concerned if you see oil
leaking from the twooil relief vents.
If you discover an oil leak, please
call or write our Technical Service
Department for parts and service
advice. (Be sure to ask about the
inexpensive seal drivers that are
available for the wheel shaft and
tine shaft oil seals.)
B. Checking gear oil levels
At every 30 hours of operation
you should check the levels of the
gear oil in the power unit and the
tine attachment transmissions.
Serious damage can result if the
transmissions are allowed to run
for even a short time without the
proper amount of oil.
The transmissions should be
cool when checking the oil levels
as the oil can expand if hot and
thus give a false reading. Also, the
power unit and tine attachment
must be connected when checking
(or adding) gear oil.
6-6: Remove oil level check plug.
To check the Power Unit oil level:
1. Make sure the tiller is on level
ground. Pull the Depth Regulator
Lever up until the tines are resting
on the ground.
2. Use a %-inch wrench to remove
the oil level check plug that is
located above the wheel shaft on
the left side of the transmission
(Photo 6-6).
3. If the oil level is correct, oil
should begin to seep out of the
hole as you remove the plug (be
patient in cold weather as the oil
may flow very slowly). If it does,
your check is finished and you
should securely replace the plug.
If there is no sign of oil, see the
“Adding Gear Oil” instructions
that follow these oil level check­
ing procedures.
To check the Tine Attachment oil
level:
1. Make sure the tiller is on level
ground.
2. If the tiller has been operated
for 30 minutes or more within the
last hour, move the Depth Regula­
tor Lever all the way down until it is
engaged in its highest notch. This
places the transmission in the cor­
rect position to take a “Hot” oil >
level reading.
J)4n^
If the tiller has not beenopef^
ated within the last two hours, you
should also place the Depth Regu­
lator Lever in its highest notch.
Then, prop up the drag bar (located
below the tines) approximately 3%
inches off the ground (using a 2 " x
4 " board on edge works well). This
places the transmission in the
correct position to take a “Cold”
oil level reading.
3. Allow the tiller to rest in this
position for at least five minutes
for a “Hot” reading or two hours
for a “Cold” reading. (Allow more
time if the air temperature is
below 40 °F).
4. Clean the area around the tine
attachment dipstick so that no de­
bris will fall into the transmission.

6-8: Tine attachment dipstick
markings.
5. Using a 9/16-inch wrench, re­
move the dipstick as shown in
Photo 6-7. Wipe the dipstick with a
clean rag and note the “Hot” and
“Cold” range markings on one side
(Figure 6-8).
6. With the markings facing to the
rear of the tiller, gently lower the
dipstick straight down into the
sump hole until the end just tou­
ches the drive shaft inside the hole
(Photo 6-9). Do not force, or try to
thread the dipstick into the hole.
Doing so will bend the dipstick and
result in an incorrect reading.
7. After a few seconds, carefully
remove the dipstick and look at
the markings. If taking a “Hot”
reading, the oil level should be
within, or slightly above, the “Hot”
range marking (checkered pat­
tern). If taking a “Cold” reading,
the oil level should be within, or
slightly above, the “Cold” range
marking.
8. If the oil level is okay, your
check is finished and you should
securely replace the dipstick. If
the oil level is low, see the instruc­
tions that follow.
