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!
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
deck lift pedal. 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 lift pedal, 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.

3. Insert the shoulder screw into the one of four index holes
in the front gauge wheel bracket 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.
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.
Brakes
The parking brake handle is an over center lever that should
engage with moderate force. To increase parking brake capacity,
adjust brake cables at the brake arms equally. Adjust the cable
housing nuts one full turn and check parking capacity. Repeat if
parking brake does not hold.
Repair: The mower is equipped with drum brakes and will not
normally require maintenance. If they are not working properly,
please contact your service center.
