Correcting Side Draft

Causes

Side draft is normally caused by having an equal angle of cut on both front and rear gangs. Since the front blades are working in firmer ground, they force the disk to the left. This exerts force on the left-hand side of the tractor drawbar, making steering the tractor difficult.

Cures

Hitch Correction

1. Remove 7/8" x 5" cap screw (A), and hex nut.

2. Swing hitch (B) to the left and use another adjustment hole in plate. Replace hardware and tighten to 603 Nm (445 ft-lbs) torque.

Lift Bar Correction

Parallel lift bar adjustment is possible by moving pin (A) to the rear of machine.

This increases pressure on rear gangs, reducing side draft.

Tractor Hitch Correction

In some conditions change tractor hitch point by turning tractor drawbar so offset is up. This will put pressure on rear gangs and decrease penetration of front gangs.

The offset disk should be pulled by a tractor with a swinging drawbar. If the tractor drawbar rides against drawbar stop, this will cause side draft and affect tractor steering.
