ELECTRONIC DRAFT CONTROL
(where fitted)
NOTE:
Depending on tractor specifiication, some of
the Electronic Draft Control features shown in this
section may not be fitted.
This system described here is known as Electronic
Draft Control. This electronically controlled hydraulic
system senses changes in the draft loading via
sensors in the lower link pins of the 3--point linkage
and changes in the position of the linkage via a
sensor on the cross shaft. The system functions in
Position Control or Draft Control.
Position Control
provides accurate control of
implements, such as sprayers, rakes, graders, etc.,
that operate above the ground. Once implement
height has been set, the system will maintain the
selected position irrespective of any external forces
acting upon it.
Draft Control
is designed for mounted or
semi-mounted implements operating in the ground.
Changes in soil resistance cause the draft loading on
the implement to increase or decrease.
Draft Control Operational Notes
Draft control sets the working depth in the soil by
maintaining a constant draft load. If the Position
Control lever (1), is set just below the normal Draft
Control working depth, it will prevent the implement
from ‘diving’ or working too deep if an area of soft or
light soil is encountered.
Position Control will override draft control when the
Position Control lever is moved above the working
depth set by the draft loading wheel (2). Therefore,
the Position Control lever can be used to lift the
implement out of the ground, from the normal Draft
Control working depth, without changing the Draft
Control setting.
This function can be useful when a gradual lift out is
required. The thumbwheel stop can be set so that the
Position Control lever can be returned quickly to a
lower limit position just below the normal Draft
Control working depth.
The raise/lower switch would normally be used to
raise or lower an implement during a work cycle.
