8.1 Swing
The handle nearest the center of the tractor, in the bank of four valves, actuates the SWING cylinder. This
valve has three positions and operates in three ways.
Push the valve handle forward and you admit hydraulic fluid to the Rod End of t he SWING cylinder, causing
the boom to swing out to the right side of the tractor. (See Diagram).
If the handle is released, the valv e will automatically return to center, and the boom will be LOCKED in
position.
Pull the valve handle back towards you and admit hydraulic fluid to the dead end of the cylinder causing the
boom to swing back toward the rear of the tractor. If the handle is continually held in this position, the boom
will continue to the left side of the tractor.
Again, if the valve handle is released, the valve will automatically return to center and the boom w ill be
LOCKED in place.
BOOM SAFETY VALVE - If a rigid object (guard railpost, tree, etc.) is struck by the extended boom while the
unit is moving forward the bo om safety valve will allow th e boom to swing rearward, and minimize the
possibility of damage.
NOTICE: This device will NOT work if the unit is mowing BACKWARDS and the boom is in the full forward
position.
ALWAYS SWING THE BOOM 10 DEGREES TO 15 DEGREES TO THE REAR WHEN CUTTING IN
REVERSE.
OPS-B 0032_B
Make certain that the Boom swing path is clear of bystanders, powerlines, and obstructions
to prevent injury, electrocution, and possible machine damage. Swing Boom SLOWLY
