DESCRIPTION
The hydraulic self-leveling option is designed to be incorporated into Bush Hog’s standard loader hydraulic circuit. A dual self-
level valve controls flow throughout the system so as to maintain a nearly constant position of the loader attachment relative
to the ground. The valve performs this function in both the raising and lowering mode. The bucket (or other attachment) may
be operated at any time, independent of the self-level valve, giving the operator the ability to reposition it throughout the work
cycle.
NOTE: IF THE LOADER ATTACHMENT ROLLS COMPLETELY BACK WHILE LOWERING THE BOOM, DOWNWARD
MOTION WILL CEASE; ROLL THE ATTACHMENT FORWARD TO CONTINUE LOWERING.
ADJUSTMENT
Since the same self-level valve is used on different Bush Hog loaders, adjustment of the valve may be required when installed
on one particular loader or the other to obtain a preferred performance. There are two separate adjustment screws, one for the
raising mode and one for the lowering mode. Remove the dust cap to access the adjustment screw and loosen the jam nut
prior to adjusting. Adjustments should be made in 1/4 turn increments to achieve the desired motion according to the following
logic:
RAISING:
Clockwise - More Rollback
Counterclockwise - More Dump
LOWERING:
Clockwise - More Dump
Counterclockwise - More Rollback
Being a “needle valve” type adjustment, a point is reached when backing the adjustment screw out further (counterclockwise)
has no effect. The maximum effective range of adjustment in this situation is approximately 2-3 turns.
