b. The front-to-rear leveling of the blades should be between level (preferred) to .25" lower at the front
of the blades but never higher at the front.
c. Use the lowest holes in tractor frame for heights of 3.25" - 4.5".
Temporary Height-of-Cut Adjustment: using the caster shims (or "C" spacers) you can adjust the blades
downward temporarily .5" or 1" below the original coarse setting as described above. This assumes that
the blades are level with two shims (or "C" spacers) on the bottom and one shim on the top of the caster
support arm. With the blades level at this assumed starting point, you should never move all of the shims
to the bottom since that would make the blades higher at the front.
The angle of attack of the blades should always be level or lower at the front. This makes the blade cut
the grass only once and saves fuel and wear on the whole mower. It also allows more efficient mowing
and grass catching or dispersal. If you mow in an area of the country where the lawn is very thick and
spongy you may have to set these two adjustments as they would appear on the grass and not on a hard
surface due to the tires “floating” up on or “sinking” down into the lawn.
Fine Adjustment: Adjust the blades equally in five settings up or down 0.25" each in a 1.25" total range.
The shims on the blade bolts are moved from under the spindle to the top of the spindle. If possible,
leave at least one shim at the top and the bottom of the spindle shaft. Using the maximums and
minimums of these methods gives you a total range of 2.75" from 1.75" to 4.5" in eleven distinct settings.
The factory setting is 3" when measured to a hard floor surface at the front of the deck.
6.3 Belt Tension Adjustment
The pump drive belt is self-adjusting, and requires no adjustment, just replacement. The blade drive belt
is self-adjusting also and requires no adjustment, just replacement.
6.3.1 Replacing the Cutter Deck Belt
•
Stop the engine, remove the key and wait for all moving parts to stop.
•
Remove the deck cover.
•
Remove the belt by using a ½” ratchet and extension to relieve the belt tension.
•
Reinstall in reverse order. Figure shows belt routing and spring compression direction.
