Check the Mower Blade Bolt Torque
WARNING
Avoid injury! Mower blades are sharp.
• Mower blades are sharp. For your personal safety, do
NOT handle mower blades with bare hands.
• Careless or improper handling of blades may result in
serious injury.
• Blade mounting bolts must each be installed with a
flat washer and then securely tightened. Torque blade
mounting bolts to 120 ft. lbs. (163 Nm).
1. Lock the mower deck in it's highest cutting position.
2. Check that the blades are installed with the tabs
pointing up (A, Figure 11) towards the deck as showing
in Figure 11.

3. Check that a flat washer (B) is installed between each
blade and the head of it's mounting bolt (C).
4. Wedge a wooden block (D) between the mower blade
and the mower deck housing to keep the mower blade
from turning. Torque each mower blade mounting bolt to
120 ft. lbs. (163 Nm).
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 12) 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 TRANSPORT 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 13) 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 14), loosen the jam
nut (B) on the ball joint (C) then remove the 1/2" bolt (D),
washer (E), and 1/2" nylock flange nut (F) fastening the
ball joint (G) to the lift pivot arm (G). Turn the ball joint
clockwise to shorten the distance between the rod pivots
or counter-clockwise to lengthen the distance between
the rod pivots until the measurements between the lift
pivots and the rod pivots are the same. Reinstall the ball
