24. Hydraulic Feed Control:
The machine with the hydraulic feed hopper is de-
signed 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 attach-
ing 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 func-
tion 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.
