A - Rockshaft Position Control Lever

B - Rockshaft Draft Control Knob

C - Position Control Lever Stop

The rockshaft is equipped with variable draft control system.

Use draft load sensing when:

• Operating with a fully mounted implement in hill and swale terrain. The implement will raise and lower to follow the ground contours while maintaining a nearly constant depth.
• Operating in varying soil conditions. The implement is raised slightly to get through tough spots so you do not have to shift to a lower gear.

Draft control knob (B) controls amount of load required before hitch responds. With knob placed all the way down, there is no draft sensing. Pulling the knob up reduces the amount of draft load required to override the position set by position control lever (A) and to raise the rockshaft.

For draft load sensing operation (Cab):

• Initially, place position control lever (A) in its fully forward position and draft control knob (B) in the lowest (least draft) position.
• With tractor moving, pull position control lever (A) backward to set implement operating depth. Set position control lever stop (C) so control lever can be brought back to the same exact position. When the tractor begins to slip, pull draft control knob (B) upward until desired draft sensing level is obtained.
• The position control lever (A) can also raised slightly to override the draft control setting to help get through slippery spots without getting stuck.
• The position control lever (A) can be moved fully rearward to raise the hitch at the end of the field.
