6.7 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 center for belt adjustment.

6.8 ADJUSTING CUTTING HEIGHT

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 6-7.

Caster spacers also can be repositioned to change the cutting heights and to change the pitch of the cutter deck. See Figure 6-8.

LOW CUT (1-3/4" to 3")

MID RANGE (2-1/2" to 3-3/4")

HIGH CUT (3-1/4" to 4-1/2")
