4. Place a 1-1/2" block under each arbor spindle to insure
that the mower maintains a level positoin. Be sure all roller
bracket linkage is free to slide in slotted holes (that the
rollers are not holding the mower up). Tighten the front
bracket at "A" first, then tighten the rear bracket at "B"
5. Remove the 1-1/2" blocks.
Repeat Step No. 3, then
proceed to Step No. 6.
6. Replace the shoulder bolts, If the holes do not line up
(without pressure) screw the eye bolt (See Figure 7) into
or out of the adjusting arms as necessary.
The mower must be mounted on the tractor to make this
adjustment. Remove the three mounting nuts holding the
belt cover on the mower housing and remove the cover.
Loosen the idler pulleys mounting nuts and move the pul¬
leys inward to increase belt tension. Move both pulleys in
their slotted mounting holes. (See Figure 8).
BELT
GUARDS
FIGURE 8
Position the belt guards as shown and re tighten the nuts.
The belt guards must be positioned 90 degrees from the belt
as shown and must NOT touch the belt when the power
take-off lever is engaged.
After the pulleys have been re¬
positioned, check for the one-fourth inch clearance on the
P.T.O. rod stop collar. (See Figure 9).
BELT STOP ADJUSTMENT
The belt guard on the tractor idler pulleys should be pos¬
itioned as shown in Figure 10.
The mower belt guards on the 28 inch mower should be
adjusted during the drive belt adjustment procedure.
FIGURE 9
POWER TAKE-OFF ADJUSTMENT
Should an attachment fail to drive properly, the power
take-off clutch may need adjusting.
The power take-off
FIGURE 10
clutch is normally in proper adjustment when there is one-
fourth inch clearance between the set collar and the end of
the bracket when engaged. If more tension is needed or re¬
adjustment is necessary, disengage the power, take-off lever,
loosen the collar set screw and slide the collar back slightly.
Tighten the set collar screw. Engage the lever and check the
belt tension. Only engough tension to drive the mower with¬
out belt slippage is necessary.
Excess tension may cause
premature failure of belts and pulley bearings.
(See Fig¬
ure 9).
