REAR THREE POINT HITCH OPERATION
Electronic Hitch System
The electronic hitch system consists of the operators control panel, the control module, two load pin sensors,
the hitch hydraulic control valve, the hitch position feedback sensor and wiring harnesses.
The Electronic Hitch System can be operated in one of two modes: 1) POSITION CONTROL and 2) LOAD
CONTROL. In position control the hitch moves with the rotation of the position control knob. In load control the
Electronic Hitch System moves the hitch to maintain a constant implement load on the tractor in changing soil
conditions and terrain.
The operator controls for the Electronic Hitch Control system consists of an indicator lamp, rocker switches,
diagnostic display and 5 control knobs.
1. Indicator Lamp
MD05F038 & MD05M023C
This lamp is used to indicate the condition of the
ELECTRONIC HITCH SYSTEM. It will stay ON for
2 seconds after the engine has started for a bulb
check. The indicator has 2 functions:
A. FLASHING - The hitch needs to be enabled.
The actual position of the hitch is not the same
as the setting of the UP/DOWN Switch or that
of Position Control.
To enable the hitch system: Set the Up/
Down switch to DOWN. Operate Position
Control until that of the control and the actual
position of the hitch are the same. When the
indicator lamp stops flashing the hitch system
is enabled.
IMPORTANT: On tractors equipped with an
Electronic Transmission the right hand
door MUST be closed before attempting to
enable the hitch.
B. CONTINUOUSLY ON - An error has been
detected within the hitch system and an error
code will have been generated. See page 141
for how to proceed.
2. Up/Down Switch
MD05F038 & MD05M023C
This switch is used to fully raise or lower the hitch. It
has 3 working positions: UP, DOWN, and
MOMENTARY.
UP - The back or left of the switch pushed down.
This fully raises the hitch from the working position
to the transport position (controlled by the UPPER
LIMIT STOP). The speed is not adjustable.
DOWN - The switch is in the centre position.
This lowers the hitch from the transport position
to full down (working position) or the position set
with the Position Control Knob. The speed is
controlled by the DROP SPEED CONTROL.
MOMENTARY - Double click and hold the switch
by pushing the front or right of the switch into the
MOMENTARY position. This will by-pass the
DROP SPEED CONTROL setting allowing the
hitch to drop at maximum speed. As long as the
momentary switch is held, the hitch will continue to
drop and will by-pass the “Bottom” setting. When
the momentary switch is released, the hitch will
automatically return to the “Bottom” setting. This
function is only active when the position control is
set in the bottom half of its range.
