4.9 Mule Pulley Adjustment
The mule pulley is located under the
engine. The drive belt passes through
the pulley to the main deck drive pulley.
Under normal operating situations, the
pulley should not be changed from the
factory set position.
However, in order to help the idler pulley
keep proper tension on a drive belt
(40-50 ft-lbs on the Cricket gauge [part
number 028498]) that has possibly
stretched, the mule pulley may be
adjusted. Simply remove the center nut
and place the pulley at the level most
appropriate to maintain the proper belt
tension.
4.10 Anti-Scalp Wheel Adjustment
The rear anti-scalp wheel on the deck can be readjusted as needed.
IMPORTANT! Any time the mower deck height is adjusted on the Articulator, it is neces-
sary to check all the anti-scalp wheels for proper positioning. The recommended
anti-scalp wheel height settings are as follows:

Deck Height < 2” = Set the anti-scalp wheels to the top hole,

Deck Height 2” to 3” = Set the anti-scalp wheels to the center hole,

Deck Height > 3” = Set the anti-scalp wheels to the bottom hole.
