The rockshaft may be 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 lever (B) controls amount of load required
before hitch responds. With lever placed 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. (See Positioning Center Link in this section
for additional information.)
For draft load sensing operation:
•
Initially place position control lever (A) in its fully
rearward position and the draft control lever (B) in the
fully forward (least draft) position.
•
With tractor moving, push position control lever (A)
forward to set implement operating depth. Set position
control lever stop (D) so control lever can be brought
back to the same position. The operating depth set-up
will prevent the rockshaft from lowering all the way
when the tractor begins to slip. Then pull draft sensing
lever (B) rearward until desired draft sensing sensitivity
is obtained.
•
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.
