4. With the parking brake engaged measure the
compressed spring length. The spring should measure
2-3/4" (7 cm) when compressed.
5. If the spring length is not 2-3/4" (7 cm), release the
parking brake, and turn the adjustment nut (B) to
compress or release the spring.
6. Engage the parking brake and re-measure the spring.
CAUTION
Do not adjust the spring to be shorter than 2-1/2" (6.4
cm) when compressed. This may damage the brake
mechanism.
If this does not correct the braking problem, see your
dealer.

Deck Lift Rod Timing Adjustment

Checking the Deck Lift Rod Timing
1. Park the machine on a flat, level surface. Disengage the
PTO, engage the parking brake, turn off the engine and
remove ignition key. Check that the tires are properly
inflated.
2. To check the lift rod timing, measure and record the
distance between the lift pivots (A, Figure 48) and the rod
pivots (B). Repeat for the other side of the unit.

3. If the measurements for the rods are equal, no further
adjustment is required. If the measurements are not equal
(greater than 1/8" (3.17 mm) difference), adjustment is
required, continue with Adjusting the Deck Lift Rod
Timing.
Adjusting the Deck Lift Rod Timing
1. Lock the deck lift pedal in the 4-1/2" (11.4 cm) position.
Remove the cutting height adjustment pin and lower the
mower deck.
2. To ensure that the deck is in the lowest position, push the
pedal by hand towards the rear of the unit and install the
height adjustment pin in the 3" (7.6 cm) position to hold in
place.
3. Block up the mower deck with 2 X 4's (B, Figure 49) until
all hanger chains are slack. The arrow (A) indicates the
front of the mower deck.

4. To adjust the deck lift rod (A, Figure 50), loosen the jam
nut (B) on the clevis (C) then remove the 1/2" clevis
pin (D), spacer (E) and hair pin (F) fastening the clevis
to the lift pivot arm (G). Turn the clevis clockwise to
shorten the distance between the rod pivots until the
measurements between the lift pivots and rod pivots
are the same. Reinstall the clevis on the lift pivot arm
and secure with the 1/2" clevis pin, spacer and hair pin
previously removed. Tighten the jam nut against the
clevis.
