2.Loosen the inner jam nuts at the rear left and right of the horizontal threaded rods. See Fig. 6-9.

3.Start at the rear right to raise the rear of the deck, tighten the rear outer jam nut to raise the deck or loosen the rear outer jam nut to lower the rear of the deck.

4.Adjust the rear jam nut at the rear left to take the “slack” out of the threaded rod.

5.Tighten both inner jam nuts to secure the deck adjustment.

6.The final adjustment would be to take the “slack” out of the left rear linkage if the rear of the deck was raised by adjusting the jam nuts on the eyebolt. Loosen the jam nuts and tighten the upper nut to remove “slack”.

7.In many cases it will be necessary to adjust deck height using both eyebolt adjustments and pitch adjustment to achieve the correct blade-to-ground heights. If you remember that the front right blade tip adjustment is fixed and you level to that height, adjusting the decks will be simplified.

5.Once the deck is level one may find that the height of cut does not match the height of cut indicator. A final adjustment may be made by lowering or raising the height of cut link accordingly. To raise the deck: remove the shoulder bolt mounting the height of cut link to the lift handle and reassemble the shoulder bolt in the lowest of the three holes. To lower the deck: remove the shoulder bolts mounting the height of cut link, flip the height of cut link around and reassemble the shoulder bolts in the top of the set of three holes and the bottom hole.

Adjusting the Deck Corner Gauge Wheels

Warning! Keep hands and feet away from the discharge opening of the cutting deck.

NOTE: The deck gauge wheels are an anti-scalp feature of the deck and are not designed to support the weight of the cutting deck.

The mower deck cutting height can be set using the tractor’s power implement lift. The deck heights range from 1” to 4”. The deck gauge wheel position should be approximately 1⁄4 to 1⁄2” above the ground when the deck is set in the desired height setting.

Using the power implement lift, set the deck in the desired height setting, then check the gauge wheel distance from the ground below. If necessary, adjust as follows:

1.Visually check the distance between the front gauge wheels and the ground. If the gauge wheels are near or touching the ground, they should be raised. If more than 1⁄2” above the ground, they should be lowered.

2.Remove the lock nut securing one of the outer front gauge wheel shoulder screws to the deck. Remove the gauge wheel and shoulder screw. Refer to Fig. 6-10.

3.Insert the shoulder screw into the one of three index holes in the front gauge wheel bracket and spacer that will give the gauge wheel a 1⁄4” to 1⁄2” clearance with the ground.

4.Note the index hole of the just adjusted wheel, and adjust the other gauge wheels into the respective index holes of the other gauge wheel brackets on the deck.

Adjusting the Center Gauge Wheels

Adjust the center gauge wheels to the same height as the outer gauge wheels. Be sure to insert the hex screw through the washer, the wheel bracket, the spacer and wheel and then the center shaft.
