The large turn buckles on the front of the deck only affect
the pitch of the deck or the level from front to back.
The deck spring tension is critical. If the tension is too
much, it will cause the spring to break. If too loose, the belt
can jump off or slip on the pulleys and cause a cut quality
issue. With the deck up, the spring coil gap should be about
.025” - .030” (about the thickness of a credit card). Spring
tension adjustments can be made by sliding the bolt shown
above forward or backward in the slot of the deck.
The condition of the blades can drastically affect the cut
quality of the mower deck. Replace as necessary. These
blades were used considerably too long. Resharpening is
recommended by professionals only to determine when
the blade needs to be replaced and because of the need for
rebalancing.
To change blades, it may be easier to use a piece of wood to
keep the blade from turning so that the bolt can be loosened.
Re-torque the blade bolts to 90-110 .lbs.
The blade spindles contain a sealed ball bearing in the top
and bottom of the
spindle. The bearings
are replaceable for a
more cost effective
repair.
