Woods Equipment RB750-4, RB850-4 manual Blade Angle Adjustment, Reverse Blade

BLADE ANGLE ADJUSTMENT

CAUTION

„Before changing positions of manual swing, tilt, or angle positions:

•Park tractor on level ground, apply parking brake, level implement boom, shut off tractor, and remove key.

•Make manual changes slowly and carefully to prevent hazardous movement of mecha- nisms.

•Never stand in positions where you could become entrapped during adjustment changes or if the 3-point hitch suddenly lowers.

„Always secure lock pins with safety pins to pre- vent lock pins from bumping out of the positioning holes. Failure to do so may result in accidents and/or damage to blade.

Mechanical

The blade may be angled 15, 30, 45 and 60 degrees for forward grading, and 15 and 30 degrees for backfill- ing to right or left from center position without unhook- ing the blade from the tractor.

1.Raise the blade a few inches off the ground by operating the lift control lever of the tractor 3-point hitch.

2.Remove the safety pin (10) and lock pin (2).

3.Set blade at desired position and replace pins.

Hydraulic

The blade may be angled 45 degrees or to any position in between, to the right or left by hydraulic remote con- trol from the tractor seat.

1.Raise the blade a few inches off the ground by operating the lift control lever of the tractor.

2.Actuate the control valve the angling cylinder is connected to.

3.On tractors with two circuit selector valves, select angling circuit and actuate the tractor control valve connected to selector valve.

NOTE: Do not operate the selector valve under load.

REVERSE BLADE

The blade is reversible without removing it from the tractor.

1.Raise blade off the ground.

2.Mechanical – Remove the lock pin (2), Figure 2, and rotate it counter-clockwise to the desired position and replace pins.

3.Hydraulic – Detach the angling cylinder (7) from the hydraulic angle arm (1), Figure 3, and rotate it counter-clockwise to the desired position. Attach angling cylinder (7) to hydraulic angle arm (1).

NOTE: In some cases it may be necessary to offset to the right and tip up the right end of the blade to rotate it.
