used to control the lowering
of the front hitch. Turning
the handle on the front hitch
valve counterclockwise (1) increases the speed at
which the front hitch and attachment can be lowered.
Turning the handle clockwise (2) decreases the speed
at which the front hitch and attachment can be
lowered.
The front hitch and attachment can be locked in any
position, so that it will not lower, by turning the front
hitch valve handle clockwise until it is completely
closed. When operating 3 point hitch implements, it
may be helpful to lock the front hitch and attachment
in a raised position, to prevent accidental lowering of
the front attachment.
