• Carefully turn the outer blades of the mower deck so that the
ends of the blades point to the front and rear of the deck. See
Figure 21.

• Measure the distance from the front cutting edge tip of the
blade to the ground. Then measure the distance from the
rear cutting edge tip to the ground. Repeat to measure the
outer blade on the other side of the deck. The front blade tip
measurement should be approximately 1/4" less than the rear
measurement, and the measurements should be approxi-
mately equal from side to side.
• If the difference between the front and rear blade tip heights
is greater than 1/4 inch, the front lift rods assemblies should
be shortened. If less than 1/4 inch, the rod assemblies should
be lengthened.
• If adjustment is necessary, loosen the jam nuts and turn them
away from the ball joints on the front end of the front lift rod
assembly on each side of the tractor. See Figure 22.
• On each side of the tractor, use a 9/16" wrench on the flats
of each rod to turn the rod. Turn each rod as shown in Figure
22 to shorten the rod and raise the front of the deck, or to
lengthen the rod and lower the front of the deck.
• Adjust both front lift rods in small increments, while continuing
to re-measure the front and rear blade heights. When the
deck is approximately 1/4" lower in the front, re-tighten the
jam nuts against the front ball joints.

• If performing the initial leveling of the mower deck, re-position
the blades and re-check the side to side level of the deck as
described in the previous sub section "Side to Side Leveling."
