OPERATION
6.1 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 cutterbar.
Release the lever and it will automatically return to
the center position to lock the cutterbar into position.
Moving the "lift" lever down will lower cutterbar.
Lift the 'tilt' lever and the cutterbar tip will arc up
toward the operator. Push down on the tilt control
lever and the tip of the cutterbar will rotate down.
Release the lever and it will automatically return to
center position to lock the cutterbar into position. By
pushing the lever all the way down, it will lock into
float detent position. This allows the cutterbar 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 cutterbar 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 cutterbar 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.
6.2 Motor Control
The motor starts when the button on the control stand is pulled out and tractor engine is running. The motor
rotation cannot be reversed; The toggle switch is only used for Switchblade units to clear debris from cutterbar.
The blades should only turn in the clockwise direction as viewed from the top. During installation, the toggle
switch reversing function is defeated.
6.3 Mower Break Back
When the mower strikes the guardrail while traveling forward, it will break back against the return spring. The
mower will return automatically to cutting position when the guardrail is passed. NOTE: the Break-Away
System only allows the cutterbar to break back. Do not back the tractor or allow it to roll back with the
rear of the mower against an obstruction. Severe damage to the mower or related components may
result.

operating parts of the mower head. These items could then swing outside the housing at
greater velocities than the blades. Such a situation is extremely hazardous and could result
in serious injury or even death. Inspect the cutting area for such objects before mowing. Remove any like
object from the site. Never allow the cutting blades to contact such items.
