Loosen the inner jam nuts at the rear left and right of the 

2. 

horizontal threaded rods. See Fig. 6-8.

Start at the rear right to raise the rear of the deck, tighten 

3. 

the rear outer jam nut to raise the deck or loosen the rear 

outer jam nut to lower the rear of the deck.

Adjust the rear jam nut at the rear left to take the “slack” 

4. 

out of the threaded rod.
Tighten both inner jam nuts to secure the deck adjustment.

5. 

The final adjustment would be to take the “slack” out of 

6. 

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”.

In many cases it will be necessary to adjust deck height 

7. 

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.

Once the deck is level one may find that the height of 

5. 

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:

Visually check the distance between the front gauge 

1. 

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.

Remove the lock nut securing one of the outer front gauge 

2. 

wheel shoulder screws to the deck. Remove the gauge 

wheel and shoulder screw. Refer to Fig. 6-9. 

Insert the shoulder screw into the one of three index holes 

3. 

in the front gauge wheel bracket and spacer that will give 

the gauge wheel a 1⁄

4”

 to 1⁄2

” clearance with the ground. 

Note the index hole of the just adjusted wheel, and adjust 

4. 

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.

Adjusting the Rear Rollers

The rear rollers help prevent the scalping of high spots and 

uneven terrain across the center section of the deck. The rollers 

can be adjusted downward or upard 1”. Lowering the roller 

will increase the striping effect left behind the mower. This 

positioning of the rear roller will also help to filter the mulched 

grass clippings into the turf.

NOTE: 

Roller should not be lowered if the cut height is set at 2-1⁄2

” 

or lower.
