MOVING UNIT WITHOUT POWER
The hydro pumps are equipped with a dump valve
(Refer to Fig. 3) that allows the unit to be moved
without power by deactivating the pump. With the
dump valve lever in normal operating position
the fluid in the pump will make it difficult to
move the unit (even with the steering levers in
neutral position). The dump valve is located on
the bottom toward the right front of each hydro
pump. Activate the dump valve by rotating
counter-clockwise with a .625 inch wrench. Ro-
tate one revolution. When BOTH hydro pumps
are deactivated the unit becomes “freewheeling”
allowing it to be moved. Before the hydro pumps
become operational the dump valves must be
returned to their normal operating position.
Do not tighten above 120 in lbs (10 ft lbs)
(14Nm) maximum.
STEERING LEVER OPERATION
(refer to Fig. 4, page 21)
Do not move steering levers from
forward to reverse or reverse to
forward position rapidly. The sudden
change could cause loss of control or
damage to equipment.
The Grasshopper tractor is very
unstable without an attachment.
Move very slowly when attachment is
removed. Never carry passengers.
