24. Hydraulic Feed Control:
The machine with the hydraulic feed hop-
per is designed with a control lever to place
the hopper in FEED - OFF/NEUTRAL - RE-
VERSE. Pull all the way out to feed, push
in to the first detent for off or neutral and
fully in for reverse. In reverse the material
in the hopper is pulled out of the rotor.
Use reverse when the rotor is overloaded,
jammed or plugged.
IMPORTANT
Check the function of the control
lever when attaching the hydraulic
lines to the tractor. The hopper
must feed in when the lever is
moved out. If it does not, reverse
the hoses.
The control lever
must function like the drawing
on each side of the hopper or
the hoses must be reversed
.
Use the flow divider valve to set the speed
of the feed hopper. Use the quality of the
job being done to establish the required
feed speed. Increase the speed when
chipping brush or twigs. Decrease the
speed when chipping hard, solid material
or when the engine is being pulled down.
