To
Drain
and
Fill
the
Tine
Attachment
Transmission:
1. The tine attachment transmis-
sion
is
not equipped with an oil
drain plug.
To
drain just a small
amount
of
gear oil, remove the
dipstick and tilt the attachment for-
ward (first uncoupling it from the
Power Unit).
2. For complete drainage, remove
the left-side tine assembly (refer to
Bolo Tine Maintenance for instruc-
tions), then remove just one
of
the
lower screws from the tiller hous-
ing cover (Photo 5-10).
To
speed
drainage, remove the tine attach-
ment dipstick to vent transmission.
Maintenance/Repairs
3. Once all gear oil has drained,
reinstall the housing cover screw
securely (first coat its threads with
non-hardening gasket sealant).
4. Be certain to refill the transmis-
sion with the correct amount
of
gear oil before operating the tiller
again.

A.
Measuring
and
Adjusting
Drive
Belt
Tension
On a new tiller (or
if
a new belt
is installed), the belt tension will
probably need to be adjusted after
the first two (2) hours
of
operation.
Thereafter, check belt tension
every ten
(l0)
operating hours.
Maintaining the right tension is
important to good tiller perfor-
mance and long belt life.
If
too
loose, the belt will slip on the pul-
leys, and be unable to deliver full
power to the wheels and tines. A
loose belt will also wear prema-
turely.
While checking belt tension,
also inspect the belt for cuts,
cracks, deterioration, etc.
Don't
continue using a belt that isn't
in
good shape. You're sacrificing
tiller performance by doing so.
Tips on keeping the drive belt
in
top condition include:
• Always put the Wheelsrrines/
PTO Drive Lever
in
NEUTRAL
when the tiller is not
in
use.
• Keep tension adjusted correctly.
•
Don't
"speed shift" when mov-
ing the Wheelsrrines/PTO Drive
Lever between FORWARD and
REVERSE.
How
to
Measure
Belt
Tension:
1. Before taking a measurement,
be sure the linkages and pivot
points on the Wheelsrrines/PTO
Drive Lever are clean and lubri-

cated.
If
there
is
any binding, you
won't
get true measurements.
Also, you'l! need the belt adjust-
ment tool you received with your
new tiller (see Photo 5-11).
2. Move the Wheelsrrines/PTO
Drive Lever fully down to the
FORWARD position. The clutch
roller at the bottom
of
the lever
should be positioned underneath
the belt adjustment block (Photo
5-12).
Don't
let the clutch roller
move during the next few steps.
If
it moves, you'll get a false belt ten-
sion reading.
