6.2 Height-of-Cut
Before adjusting the height-of-cut be sure the mower
blades are off, and the rear tires have proper air pressure.
Check for even tire wear. The height-of-cut can be
adjusted the following way:
• The cut height is set by allowing the foot lever to rest on
a detent pin inserted into the height selection plates. To
set the height of the pin, raise the mower deck to the
transport height position and lock in. This is achieved
by pressing the pedal all the way forward until the latch
system engages the pedal and locks the deck up in the
transport position. With the load removed from the
detent pin, it can be changed to the desired cut height.
Once the pin is securely connected to the selector plate,
the deck can be lowered to the desired cutting height by pressing in on the deck-lift foot pedal until the
latch releases the pedal. Now the deck can be lowered until it comes in contact with the pin.
6.2.1 Deck Adjustments
The mower deck can be adjusted for pitch and side-to-side levels. Pitch is the relationship between the front
off the blade and the rear of the blade in regards to the height of the cut. A positive pitch (front of the blade
is lower than the rear of the blade) of ¼” is the optimum setting.
Each of the four chain hangers connecting the mower deck to the lift assembly has an adjustable pivot
plate located on the top of the mower deck. On a flat and level surface, the pitch and side-to-side variation
should be checked regularly. Note: it is necessary to have a front to rear pitch of 1/4 inch aiming the front
of the deck toward the ground. Adjust one side at time when setting deck height adjustment.
If the deck is leaving stripes, it may be necessary to check the adjustment on the four deck hangers.
6.3 Belt Tension Adjustment
The pump drive belt is self-adjusting, and requires no adjustment. The blade drive belt is self-adjusting
also and requires no adjustment. Replace tension idler assembly if worn or failing to maintain proper
tension.
