Do
not
use draft
control
with implements not designed
for
this. You
will
lose
all the advantages
which
draft
control offers, and these are:
-smoother
running
of
the engine.
-the
possibility
to
work
at a greater depth.
-better
ground
grip
and so less tire wear.
-less
fuel
consumption
.
An
example
for
the use of
draft
control
Supposing we
want
to
plow
at a depth of, say 8"
(2
0 cm): at the beginning
of the
furrow
drop
the
plow
to the ground and move the
lift
contr
ol lever pro-
gressively lower wh ile the
tractor
continues to advance, until the required depth
is achieved.
After
working
depth
has been set,
it
is
convenient
to adjust the responsive
sensitivity
accordnig
to
the
indications
on page 87.
During the run no other action must be taken except in the case
of
large
variations in resistance to the implement
which
require movement of the
lift
control
lever to maintain the desired depth.
Selection
of
the
operation
system
The selection of the operation system (position and
draft
control)
depends
upon the type
of
implement used. The system to be adopted for the implement
of
current
usage is
indicated
in
the table "
Guide
to
Lifter
Use
".
HITCHING POINTS
For
correct
lifter
operation the implements must have the
hitching
points
located as shown in fig.
29
.
NOTE:
THE PLOW SHOWN
IS
JUST AN EXAMPLE: THE
DATA GIVEN ABOVE HOLD HOWEVER FOR ALL
TYPES
OF
IMPLEMENT. USE THE SHORTEST POS-
SIBLE IMPLEMENTS WEIGHING NOT OVER
990 lb.
(450 Kg.)
