OPERATING CONTROLS
The principle components and controls of your rotary
mower are identified in Figure 1 with the same description
used throughout this manual.
All controls are located near the operator's position on the
tractor. The mower blades are placed in motion by en-
gaging the attachment drive clutch lever. The desired
mowing height can be adjusted with the height selection
lever.
Generally best performance is obtained with the transmis-
sion in Low range and the engine running % to full throttle.
The throttle should be set as low as practical to obtain
maximum fuel economy but high enough to prevent engine
lug down or labor which could cause overheating and poor
mowing.
Adjust the tractor ground speed with the travel
lever according to your mowing conditions.

OPERATION
1.
Keep mower blades sharp and balanced as covered in
the Maintenance Section of this manual.
2.
Operate engine at approximately % to full throttle and
regulate the ground speed Travel Lever according to
mowing conditions. As a general rule, set the throttle
as low as practical to obtain maximum fuel economy
but high enough to avoid engine lug down or labor
which could cause overheating and poor mowing per-
formance. Unless grass is unusually light, always
operate in "Low" speed range.
3. If grass is heavy and higher than normal, results can be
improved by mowing twice. Make the first cut with the
6
mower set higher than normal; then repeat with the
mower set at desired finished cut height. When mowing
heavy grass, always discharge clippings away from the
uncut area.
WARNING: Be sure that the at-
tachment drive clutch is off, the
engine is shut off, the key removed
^^^^^^ and the blades have stopped
spin-
^^K^^B ning before attempting to clean a
plugged discharge chute.
