HYDRAULIC LIFT
The hydraulic
lift
installed on tractor offers three
types
of
operation: position control, floating and
draft
control. Each operation is selected
to
suit
the
job
application, the type
of
implement and
the physical characteristics
of
the soil.
POSITION CONTROL
Position Control permits the operator
to
use the
Implement at any position which he selects
either
In
or
out
of
the ground, according
to
the
positron on the quadrant
at
which he places the
lift
control lever (Item
A,
Fig. C.0/1). The move-
ment
of
the Implement is proportional
to
the
movement
of
the lever.
