Using Draft Control
The rockshaft is equipped with a variable draft control system.
Use draft load sensing when:
· Operating with a fully mounted implement in hilly 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 lever (B) controls amount of load required before hitch responds. With lever moved fully forward to the position marked "off" (C), there is no draft sensing. Placing the lever toward the rear position reduces the amount of draft load required to override the position setting set by the position control lever (A) and raise the rockshaft.
Draft sensitivity ranges can be changed by repositioning the center link (for further information refer to "Positioning Center Link" in this section).
For draft load sensing operation, initially move position control lever (A) in its fully forward position and the draft control lever (B) in the fully rearward (least draft) position. Then, with the tractor moving, push the draft control lever forward to increase the load to the desired setting.
Pull control lever (A) rearward to set maximum depth of implement. Set position control lever stop (D) so control lever can be brought back to the same position each time. The maximum depth will prevent the rockshaft from lowering all the way when the tractor begins to slip. The position control lever (A) can also be 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.
