Engine Adjustments - Cub Cadet 997 Operator's Manual

The front wheel cutting height is determined by
selecting one of six positions on each caster assembly.
To adjust front cutting height, proceed as follows:
• Remove the wing nut from the axle bolt. See Figure
13. Slide the axle bolt and spring washer from the
assembly and select a cutting height.
• With the spring washer on the axle bolt, reinsert
hardware in the square hole desired through the
wheel assembly and secure with the wing nut
previously removed.
All wheels must be placed in the same

relative position. For rough or uneven lawns, raise the

Caster Lock Adjustment
The casters can be locked in a straight ahead position
or position to swivel freely. See Figure 13.
• Lift and place the lock pins in the larger holes to
lock the wheels for straight ahead operation.
• Place pins in smaller holes to allow casters to rotate
freely for turning.
Drive Clutch Control
The adjustment wheel is located in the drive clutch
control handle housing and is used to tighten or loosen
the drive belt. You will have to adjust the drive clutch
control if, with the drive clutch engaged, the mower
either does not self-propel or hesitate.
• To resolve the above problems, rotate the
adjustment wheel with your fingers: clockwise to
tighten the cable and counter-clockwise to loosen
the cable. See Figure 14.
NOTE: For some operators, the drive clutch control
may not be in a comfortable position. You can adjust
the handle out by tightening the adjustment wheel.
