12. NEUTRAL POSITION OF HST
WARNING:
・
After a long time of use, the neutral
position of the HST unit can shift,
which will cause various troubles such
as difficulty in stopping the machine,
changing over between forward travel
and reverse travel, etc., which is very
dangerous.
IMPORTANT:
・
When the HST unit is out of order, ask your dealers to
repair it. But when there is no alternative but for the
user to adjust it, follow the next instructions.
The neutral arm,1, of the HST unit is located around the
center on the right side of the front mower. With this arm
the neutral position can be adjusted.

b. Place the front mower on level, hard ground. Put
tire chocks in the positions a little apart from the
front wheels and rear wheels.
c. Turn the PTO lever to the OFF position (
N
).
Before adjustment make sure that the engine is
stopping to prevent accidents.
d Loosen the lock nut,2, and adjust the adjust plate,4.
e. When the front mower creeps forward, move the
adjust plate upwards, and when creeps reverse,
move the adjust plate downwards. Then tighten it
temporarily with the lock nut.
f. Start the engine and hold the throttle lever in an
intermediate position between the HIGH speed
position(
r
) and the LOW speed position(
t
).
g. Release the parking brake.

shows that the neutral position is properly set.
