MAINTENANCE/SERVICE
STABILIZER SPRING ADJUSTMENT -
36 ft. ONLY
The stabilizer spring is factory set to counteract
side draft in average field conditions. In hilly or wet
conditions it may be necessary to increase the
stabilizer effect by shortening the spring. Where
less than average stabilizer effect is required to
counteract side draft, the spring may be
lengthened.
To adjust spring length:
1.
CAUTION: To avoid injury from rapid
release of spring force, move front
hitch to transport position to relax
stabilizer spring before adjusting.
2. Loosen stabilizer spring clamps (A) and
reposition between maximum stabilizer effect
(B) and minimum stabilizer effect (C),
depending on field conditions as described
above.
IMPORTANT: Operating with spring set shorter
than position (B) may result in machine damage.
The weld bead (D) marks the clamp position for
minimum recommended spring length.
3. Move front hitch to field position. STABILIZER SPRING ADJUSTMENT - 36 ft. UNIT
