1. The mower may be operated in the fixed mode or
the
floating mode.
2.
Fixed mode height of cut ranges from 3/8 - 2-15/16
in. (9.5 - 75 mm) and the mower does not require a
front roller unless the terrain is rough and uneven.
If a front roller is required, the roller should be raised
1/4 in. (6 mm) higher than the rear roller and used for
anti-scalp purposes only.
3.
Floating mode requires a front roller.
If a 2-1/2 in. (63 mm) solid front roller is used, the
cutting height will range from 3/8 to 2-1/8 in. (9 to
54 mm).
If a 3 in. (76 mm) grooved front roller
(Recommended) is used, the cutting height will range
from 3/8 to 2-1/2 in. (9 to 63 mm).
4. To convert the mower from
fixed to floating mode,
remove hardware (H) from each side of the five
mower frames.
Install a front roller and store hardware (H) for future
conversion to fixed mode.
5. To convert the mower from
floating to fixed mode,
