3. SELF-BALANCER SYSTEM
This system reduces the stepped differences in cutting height when mowing rolling terrain.
Self-Balancer
1. The mower deck is held in place via the balancer
plate (4) and the support by the rear link (1), (2).
2. The mower deck is suspended by, and is tilted to the
right and left by, the balancer support (5).
balancer springs (3) at both sides adjust themselves
for suitable tension to keep the mower deck out of
excessive tilt.
Without Self-Balancer Type (A)
• When working on a wavy ground, the tractor itself,
with the mower deck, goes along the curves of the
terrain. If not equipped with the self-balancer, the
tractor tends to tilt itself greater than the ground's
waves by its own weight. This may cause an uneven
mowing. The wider the mower is, the more
unevenness is caused.
With Self-Balancer Type (B)
• When working on a wavy ground, the tractor itself
goes along the curves of the terrain like with the
tractor that is not equipped with the self-balancer.
The balancer springs (3), however, serve to keep the
mower deck in parallel with the ground's curves until
the anti-scalp roller (6) comes in contact with the
ground.
• If the tractor temporarily tilts itself more than the
ground's slope or the like, the anti-scalp roller (6)
touches the ground. Now the mower deck is brought
back in parallel with the ground by the counterforce of
the roller (6) just hitting the ground as well as the
tension of the balancer springs (3). This helps reduce
an uneven mowing.
NOTE
• Always keep the anti-scalp roller with specified
position (Refer to Operator's Manual).
