5.
Loosen the nuts (C) and allow the rear of the deck to rest on
the 2 x 4’s. Slide the chains down in the slots until the chains
are tight and tighten the nuts.
6.
Remove all 2 x 4 blocks from under the mower deck.
7.
Perform the Determining if the Deck Leveling Needs to Be
Adjusted procedure to verify that the deck has been leveled
correctly.
Deck Lift Assist Springs
Some models are equipped with deck lift assist springs (A, Figure
52) that assist the operator in raising the mower deck with the
deck lift pedal. The deck lift assist springs are factory set to
provide optimal lifting performance.
52
Although it is fastened with a multi-position anchor, this is not
an adjustment point.
Do NOT attempt to adjust the spring length or lifting performance
will be compromised.
Mower Belt Replacement
NOTICE
To avoid damaging belts, do not pry over pulleys.
1.
Park the tractor on a smooth level surface such as a concrete
floor. Disengage the PTO, engage the parking brake, turn
off the engine and remove the ignition key.
2.
Lower the mower deck to its lowest cutting position and
remove the mower deck guards.
WARNING
Use extreme caution when rotating the idler arm with the
breaker bar, due to the increased tension in the spring as the
idler arm is being rotated. Injury may result if the breaker bar
is prematurely released while the spring is under tension.
3.
Using a 1/2" breaker bar, place the square end in the square
hole located in the end of the idler arm (A, Figures 53 & 54)
• For 52" Models: Carefully rotate the breaker bar
clockwise, which will relieve the tension on the belt
exerted from the idler arm.
53
• For 61" Models: Carefully rotate the breaker bar
counter-clockwise, which will relieve the tension on
the belt exerted from the idler arm.
54
4.
Slide the drive belt over the edge of the stationary idler pulley
(B, Figures 53 & 54). Carefully release the tension on the
breaker bar.
5.
Remove the old belt and replace with a new one. Make sure
that the V-side of the belt runs in the pulley grooves.
6.
Install the drive belt (A, Figures 55 & 56) on the PTO pulley,
the spindle pulleys (B) and all idler pulleys (C) except the
rear stationary pulley (D).
