CUTTER DECK ADJUSTMENTS

Due to the many cutting conditions that exist, it is

difficult to suggest a cutter deck setting that will

work for every lawn. There are two adjustments

that can be made on these decks, pitch and height.

PITCH is the angle of the blades (comparing front

to rear). A 1/4" downward pitch (front of deck

down) is recommended for best cutting perfor-

mance.

HEIGHT is the nominal distance the blade is off of

the ground. This measurement is made with the

blades pointed side to side and distance is measured

between cutting tip and ground. (Also see Blade
Height Adjustment)

Changes to the cutting height can be achieved by

repositioning the cutter deck. (This adjustment will

also effect the pitch of the deck). There are three

available positions (see figure 4).

Caster spacers also can be repositioned to change

cutting heights and to change the pitch of the deck.

BLADE HEIGHT ADJUSTMENT

Adjusting the blade height can be done by moving

any number of the five smaller 1/4" spacers on the

blade mounting bolts to the top of the spindle shaft or

below the spindle shaft.

-NOTE-

All blades should be positioned equally.

For best cut and discharge, a minimum of three

spacers should be installed between the blade and the

spindle. (See figure 6)
