BELT ALIGNMENT
Belt alignment is important for proper performance of your Scag mower. If you experience frequent belt wear or breakage, see your authorized Scag service dealer for belt adjustment.
CUTTER DECK ADJUSTMENTS
Due to the many conditions that exist, it is difficult to suggest a setting that will work for every lawn. There are, however, two adjustments that should be made on the cutter deck: 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 better cutting performance.
HEIGHT is the nominal distance that the blade is off the ground. This measurement is made with the blades pointed side to side and distance is measured between cutting tip and ground.
Adjusting the blade height can be done by moving any number of the five smaller spacers on the blade mounting bolts to the top of the spindle shaft or below the spindle shaft. All blades should be positioned equally (see Spindle Illustration, p. 8).
