When selecting a cutting height, you should consider the area of operation. If the ground is rolling and has mounds the blades could contact, set the cutting height accordingly.
NOTICE
■Avoid ground contact with blades. Striking ground with blades produces one of the most dam- aging shock loads a cutter can encounter. If this occurs repeatedly, the cutter, driveline, and gear- boxes will be damaged.
The blade cutting edge is approximately

ATTITUDE ADJUSTMENT (PULL-TYPE)
Normal Mowing
For the most economical power use and best cutting results, the cutter should be from 1/2" to 3/4" higher at the rear than at the front.
For grass and weed mowing, adjust cutter to run level or with the front slightly lower.
Shredding
For shredding, it is better to set rear of cutter slightly lower than the front. How much lower depends on the material to be shredded. Determine the best setting for your situation by experimenting. Use a slow ground speed for better shredding.
DRIVELINE ADJUSTMENT (PULL-TYPE)
With the cutting height established, adjust the driveline carrier bearings in the
