BELT ALIGNMENT6.4
Belt alignment is important for proper performance of
your Scag mower. If you experience frequent belt wear
or breakage, see your authorized Scag service center for
belt adjustment.
ADJUSTING CUTTING HEIGHT6.5
The mower deck can be adjusted from a height of 1-3/4
inches to 4-1/4 inches at 1/4-inch intervals.
Due to 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 to the cutter
deck, pitch and height.
PITCH is the angle of the blades (comparing front to
rear).
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 the cutting
tip and ground. (Also see Blade Height Adjustment).
Changes to the cutting height can be acheived by
repositioning the cutter deck. (This adjustment will also
effect the pitch of the deck). There are three available
positions. See Figure 6-5.
Caster spacers also can be repositioned to change the
cutting heights and to change the pitch of the cutter deck.
See Figure 6-6.

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.
