3. Mixed control of position and draft
of 3-point hitch mounted implement
In draft control,
when draft decreases, the implement
automatically lowers to increase draft. However, the
implement sometimes lowers too much.
To limit the degree to which the implement can be
lowered, set the position-control-lever at the lowest
working depth desired for the implement. Lower the
draft-control-lever to the point where the implement is
at the desired depth.
Setting the position-control-lever and the draft-control-
lever stops the implement from going too deep and
causing loss of traction and ground speed.
