LEVELING THE DECK Synchronizing Height Of Cut (Figure 20)
CAUTION: Stop the engine, put the steering
control levers in the park position and remove
the key from the ignition before performing any
maintenance or repairs on this unit.
1. Set the front tire pressure to 20 p.s.i, and the rear tire
pressure to 12 p.s.i.
2. Place the mower on a level surface.
3. Raise the mower deck to the transport lock position
and adjust the cut height to 3 inches.
4. Lower the deck back to cut position.
5. Set both of the outside blades to be perpendicular to
the mower as shown in figure 18.
Figure 18 OM5045
6. Measure the height of the blade tips on both 1 and 2
and adjust the front adjustment bolts and the rear
U-bolts to ensure the deck is level from left to right.
7. Rotate the mower blades 90 ° so they are parallel to the
mower deck. Use the rear adjustment bolts to adjust
the deck so that the rear blade tip is 1/8" higher than
the front blade tip on the same blade.
Measure the blade heights to make sure they match what is
shown on the height of cut dial. The height is measured as
the distance between the ground and the bottom of the
blade. If the blade height does not match the dial height, see
Synchronizing Height Of Cut (Figure 20) below.
Figure 19 0E3305
CAUTION: Stop the engine, put the steering
control levers in the park position and remove
the key from the ignition before performing any
maintenance or repairs on this unit.
NOTE: Make sure the deck is level before synchronizing the
height of cut dial with the deck blade height.
1. Raise the mower deck to the transport position. Take
the weight off of the deck lift linkage (1) by inserting
wood blocks under each corner of the deck and slowly
lowering it until it is resting on the blocks.
2. Loosen the 1/2 jam nut (3) from the 1/2" adjustable
yoke (2).
3. Pull the 1/2" clevis spring pin (5) out of the adjustable
yoke and disconnect the yoke from the lift linkage (1).
If the blade height is higher than the height of cut dial,
tighten the yoke onto the 1/2-13 x 4.5" bolt (6) which
runs through the height of cut index arm weldment (4).
If the blade height is lower than the height of cut dial,
then loosen the yoke on the 1/2-13 x 4.5" bolt (6).
NOTE: Set the height of cut on the front tip of the center
blade.
4. Connect the 1/2" adjustable yoke (2) to the lift linkage
(1) with the 1/2" clevis spring pin (5).
5. Tighten the 1/2" jam nut (3) back down to lock the
setting into position.
6. Raise the deck back to the transport height and
remove the blocks from below the deck. Measure the
blade height again to ensure it now matches the height
on the dial. If not, repeat until the two heights are
synchronized.
