OPERATION
7.1 Position Controls
All operating positions of the mower are controlled
with two control valve levers. The 'lift' function
control permits selection of Up, Lock, or Down
position and the 'tilt' control may be placed in one of
four positions; Up, Lock, Down, or Float.
Moving the 'lift' lever up will raise the cutter bar.
Release the lever and it will automatically return to
the center position to lock the cutter bar into
position. Moving the "lift" lever down will lower
cutter bar.
Lift the 'tilt' lever and the cutter bar tip will arc up
toward the operator. Push down on the tilt control
lever and the tip of the cutter bar will rotate down.
Release the lever and it will automatically return to
center position to lock the cutter bar into position.
By pushing the lever all the way down, it will lock
into float detent position. This allows the cutter bar
to follow the contour of the ground. The tilt function
also incorporates an additional feature. If the tilt is
lifted to its maximum position, the lift cylinder will
engage and fully raise the cutter bar to maximum
up position. When the tilt is lowered the bar will
automatically return to the same lift height it was.
This allows the operator to use one lever to raise
the cutter bar to avoid an obstruction such as a
utility pole.
If it is necessary to hold the cutter bar in the air (in
such conditions as mowing over water, stones, or
other debris) the operator should then set the height
with the 'lift' control in the hold (center) position and
the 'tilt' control in the hold (center) position. The
valve incorporates holding components to maintain
position.
7.2 MOTOR CONTROL
The motor starts when the button on the control stand is pulled out and tractor engine is running. The motor
rotation can be reversed, to clear cutter bar, by moving the toggle switch, located above the motor switch, to
the center position, allow the cutter bar to stop and then move the toggle to the other position.
7.3 KNIFE SPEED
Operate the tractor engine at the RPM that will produce 540 PTO RPM. This will produce the proper knife
speed for the cutter bar.
