2.2.8 Conveyors, Lifting and Folding
Manual valve on the H-1130 tub grinder controls the conveyor lift and fold. The tractor supplies hydraulic oil for
operating the conveyor lift and fold system. Activate the tractor hydraulic circuit before operating the valve on the
H-1130 tub grinder.
To correct a reverse flow, either change the hoses around where they connect to the tractor, or reverse the tractor
operating lever position. On a tractor with adjustable hydraulic flow rate, adjust the oil flow to a minimum rate and
adjust for adequate function speed.
2.2.9 Hydraulic Tilt Platform
The H-1130 tub grinder can be tilted 90 degrees for access to the rotor, screens, and drive line. Operation of the
tub tilt cylinder is performed using the controls for the tractor's second hydraulic circuit which are located on the
tractor. A ball valve (3800906) is connected behind the coupler for safety purposes. The ball valve remains closed
(perpendicular) during the machine operation. After using the normal shutdown procedures, the hopper platform can
then be opened. The ball valve needs to be open (parallel) for this procedure.
WARNING: To prevent serious injury or death, do not tilt platform on unlevel ground or with
material in the tub.
WARNING: For your protection ALWAYS install the tub cylinder stop when the tub is tilted.
NEVER engage tractor PTO when the tub is raised.
