WheelsfTines/PTO Drive Lever up
in
REVERSE, while briefly
pulling out the engine start rope.
The reverse disc should turn the
lower pulley (see Photo 5-26).
If
not, or it requires a lot
of
pressure
to hold the lever up in REVERSE,
then the reverse adjustment bolt
must be adjusted downward.

4. Shift the WheelsfTines/PTO
Drive Lever to REVERSE and
then let it go. The lever should re-
turn to NEUTRAL.
If
not, the re-
verse adjustment bolt will have to
be adjusted upward.

1. Verify that the linkages for the
WheelsfTines/PTO Drive Lever
are lubricated with oil and the en-
gine mount bars and the belt ad-
justment block are lubricated with
grease. (See "Tiller Lubrication"
in this section.)
2. Place the WheelsfTines/PTO
Drive Lever
in
NEUTRAL.
Briefly pull out the engine recoil
start rope while watching the re-
verse disc. The disc should turn,
but the lower pulley should not

If
the re-
verse disc turns the lower pulley,
or
if
it
is
located closer than 3/16"
to the pulley, the reverse adjust-
ment bolt should be adjusted up-
ward (see instructions that follow).
Moving the adjustment bolt up-

The spring and plunger assem-

When the WheelsfTines/pTO
Drive Lever is moved up into RE-
VERSE, the engine and engine
mount move down to press on the
reverse adjustment bolt (see Photo
5-24). This action compresses the
reverse spring and plunger assem-
bly, requiring you to hold the lever
up
in
REVERSE. When you re-
lease the lever, the spring automat-
ically pushes the lever back into
NEUTRAL position.
