position. Make sure tire inflation has been adjusted from
shipping pressures. Front: 12 psi (82 kPa)
Rear: 20 psi (137 kPa)
Mower: 30 psi (205 kPa)
Side-To-Side
1. Turn the blades side-to-side and measure distance from
outside tips of blades to ground. Measurement should
be equal (within 1/8"). For adjustment, refer to figure 16.
a. Adjust top and bottom nuts on hook assembly (A,
figure 16) so that mower blades are level. Chains can
be connected on different links from side-to-side if
easier to adjust. Then, use nuts to make finer
adjustment. Make sure chain links are all in vertical
position without kinks.
b. Tighten nuts after adjustment Is correct.
Front-To-Back Leveling
2. Turn the blades front-to-back. On 3-blade decks,
measure the distance from the ground to the front tip of
the center blade, and from the ground to rear tips of left

hand and right hand blades. On 2-blade decks, measure
the distance from the ground to rear tip of the right hand
blade, and from ground to front tip of left hand blade.
Without operator in seat, front tip should be level to 1/8"
(3 mm) higher than rear tips. With operator in seat, front
tips will be pitched slightly higher than rear tips. For
adjustment, refer to figure 16.
a. Turn nuts (C) at rear ends of lift rods (B) to adjust
pitch. Tightening the nut will raise the front of the
mower deck.
b. Be sure to turn nuts on left hand and right hand rod
equally. If rods are not same length, mower may rock
slightly from side-to-side.
