6.0 ADJUSTMENTS ____________________________________________________________
An improperly secured tractor
ready for adjustments can
cause serious injury or be fatal.
To prevent injury, lower implements to the
ground, disengage all drives, engage parking
brake, stop engine and remove key from ignition
switch before making any adjustments or
performing maintenance.
Make sure the tractor is parked on a solid and
level surface. Never work on a tractor that is
supported only by the jack. Always use jack
stands.
If only the front or rear of the tractor is raised,
place chocks in front of and behind the wheels
that are not raised. (Ensure caster wheels are
directed rearward.)
1.
Adjustments and maintenance should always be per-
formed by a qualified technician. If proper adjustment
cannot be made, contact an Authorized Bob-Cat Dis-
tributor.
2.
Replace, do not adjust, worn or damaged compo-
nents.
3.
Do not wear jewelry or loose fitting clothing when
making adjustments or repairs.
Serious injury or death can
result from blade contact.
Be careful to prevent entrapment of the hands
and fingers between moving and fixed
components of the machine.

6.1 ENGINE TO BLADE BELT REPLACE AND ADJUSTMENT __________________________
The PTO drive belt consists of one single long belt run-
ning from the electric PTO clutch drive pulley (A) to the
top center spindle pulley of the cutting deck. Proper belt
tension is maintained by two V-idler pulleys (B) and (C).
Figure 6A
Engine to blade belt tension adjustment is correct when
the spring loaded idler pulley (B) is at its maximum height
when the cutting deck is at its lowest cutting height
position.
Replacement:
1.
Unplug the clutch from the wire harness. Remove the
two bolts that secure the clutch to the clutch stop.
2.
Lower the cutting deck to its lowest position.
The left hand idler is under
spring tension.
3.
Loosen the 1/2-13 x 2-3/4” Idler Bolt (D) that
secures the Right Tension Idler (C).
4.
Remove the old belt and check the pulley grooves
for damage or excessive wear. Replace if necessary.
5.
Install the new belt, reattach the clutch stop and
connect the clutch connector to the wire harness.
Adjustment:
1.
Lower the cutting deck to its lowest position
.
2.
Lower the Right Tensioner Idler (C) to align horizon-
tally with the Left Spring Loaded Idler (B).
3.
With the idler pulleys in this position, adjust the Belt
Keeper (E) so each leg of the keeper is 1/16-1/8”
from the belt.
4.
Secure Idler Bolt (D ) holding the right tension idler.
5.
Raise and lower the deck fully to ensure no interfer-
ence with the sprockets, idler arm, or any other
object.
