ELIMINATING DRAFT CONTROL FROM THE MAGNUM TRACTOR
Load pins (draft control) can be eliminated from the tractor by simply unplugging the draft pins and
reprogramming the hitch controller. See page 11 step 7 of the Calibration procedure for Electronic
Hitch.
Cover connector ends if draft pins are removed.
Note: If a "g" appears during calibration, the draft pins or its wiring circuit has failed,
Note: During calibration a “g” may appear in the diagnostic display. The hitch control module is
asking “Does the system have two load sensing pins?”
Answer no if the load pins are disconnected by pressing the hitch switch to the up position and then
to the down position (not to the down momentary position).
Answer yes if draft control is desired and the load pins are connected by pressing the hitch switch to
the momentary position then releasing. Normally, the control module will sense two pin and not
ask.
