6.2.1 Deck Adjustments
The mower deck can be adjusted for pitch and side-to-side lever. Pitch is the relationship between the front
of the deck and the rear of the deck in regards to height of cut. In most cases, a positive pitch (front of the
deck lower than the rear of the deck) of ¼” is the optimum setting. These two adjustments can easily be
made by using the deck lift rod assemblies attached to the front deck arms and the threaded deck hangers
located at the rear of the deck frame. These hangers are connected to the chains that hold the deck.
Adjust the rear deck hangers (by using a socket through the hole above the toe area of the platform)
to achieve a ¼” pitch. These hangers are right-han ded threads. If you raise any of these settings
above the factory setting, the deck may not raise all the way up into transport position. Be sure and
check the deck height of cut range after any adjustments are made to these hangers to ensure that
the height of cut adjustments work properly. If unable to make the adjustments needed by only
using these hangers, contact your dealer for assistance.
6.2.2 Deck Lift Assist Spring
To adjust deck spring tension, tighten or loosen the eye-bolt Nylock jam nut located in the front tank bracket.
If tightening for more lift assist make sure not to over tighten creating the deck to hop over rough terrain.
6.3 Spring platform Adjustment
The factory setting is both springs set at the most forward position.
The more rearward the spring position, the stiffer the platform gets.
Adjustment will be to preference of feel. The two adjustment springs
should at all times, be positioned next to each other not one forward
or back more than the other. To adjust, loosen each spring retaining
bolt from the top just enough to slide it, then tighten with impact
wrench. The nut may spin using hand wrench. NOTE, do not loosen
too much, if the nut falls off, the foot platform will have to be removed
to reinstall.
There is an extra hole for a third spring for operators heavy enough to
bottom out the duel spring stock set up.
6.4 Belt Tension Adjustment
The pump drive belt is self-adjusting, and requires no adjustment, just replacement. The blade drive belts
are self-adjusting also and require no adjustment, just replacement.
