Hydraulic Flow Control / Stop Knob
Lowering the 3-point hitch too fast can lead to
accident or failure.
Adjust the hydraulic flow control / stop knob so that
the time for lowering the implement from the highest
position to the lowest position becomes 2 seconds
or longer.
While on a road, do not attempt to operate an
implement. During transportation, put the 3-point
hitch control lever in its raised position and lock it
with the position stop knob.
Do not fully close the hydraulic flow control / stop
knob to hold an implement in the raised position
while the tractor is traveling with the implements.
Doing so could cause damage to the hydraulic lift
circuit.
The lowering speed of the lower link is governed by the
position of the hydraulic flow control / stop knob. This knob
directly controls the lowering speed of the lower link.
Also, this knob is used to stop the lower link at an intended
position.
IMPORTANT:
When a heavy load is installed to the 3-point hitch and
the tractor runs on rough terrain, the hydraulic system
may be damaged.
(a) Turning the knob clockwise will cause the lowering-
speed to decrease.
Tighten the knob by fully turning clockwise to stop the
lower link.
(b) Turning the knob counterclockwise will cause the
lowering-speed to increase.
Be careful to avoid injury:
NEVER use the hydraulic flow control / stop knob
for holding an implement in the raised position for
maintenance. Loss of hydraulic pressure may cause
the implement to drop suddenly. Lower the
implement onto solid blocks or remove before
starting any maintenance.
