Height-Of-Cut Adjustment - Toro Greensmaster Flex 21 Service Manual

Height–of–Cut Adjustment
1. Park mower on a level surface. Make sure engine is
OFF. Remove high tension lead from the spark plug.
2. Verify that the rear roller is level (see Leveling Rear
Roller) and that the bedknife to reel contact is correct
(see Bedknife to Reel Adjustment). Tip mower back on
it's handle to expose front roller, rear roller and bedknife.
3. Loosen locknuts securing height–of–cut arms to cut-
ting unit side plates (Fig. 17).
4. Use Gauge Bar to determine height–of–cut (see
Special Tools).
5. Loosen nut on gauge bar and set adjusting screw to
desired height-of-cut. Distance between bottom of
screw head and face of bar is height-of-cut (Fig. 18).
Tighten nut on gauge bar.
6. Hook adjusting screw head on the cutting edge of the
bedknife. Rest the rear end of the bar on the rear roller
(Fig. 19).
7. Rotate height–of–cut screw until the front roller con-
tacts the front of the gauge bar. Adjust both ends of the
roller until the entire roller is parallel to the bedknife.
IMPORTANT: When set properly, both rollers
should contact the gauge bar, and the adjusting
screw should be snug against the bedknife. This as-
sures that the height–of–cut is identical at both
ends of the bedknife.
8. Tighten both lock nuts to secure the height–of–cut
adjustment (Fig. 17).
