Draft Control; Position Control; Flow Control - Ford 2000 Operation Manual

THE HYDRAULIC
SYSTEM SECTION
B
DRAFT
CONTROL
(Figure
B1)
Draft control
is
selected
by moving the position/draft selector lever
(1
)
down-
wards. Having
set the hydraulic
main
control lever
(2),
together with the
adjustable quadrant stop (3), to
the desired
position,
the
system
will
auto-
matically
maintain the
implement
at
a
depth
relative to
the ground
contour
irrespective of
tractor
movement. Use the adjustable stop
to return the hydraulic
main control lever
to
the
same
position.
IMPLEMENT
POSITION
CONTROL
(Figure
B1
)
This control
enables an implement-to-tractor height
or
depth
to
be selected
and
maintained without any
further
adjustment.
To
operate the control
:
1
.
Set
the Position/Draft selector lovor (1) in
the
uppermost
position.
2.
Set
the
implement
to the required
working height or
depth by
using the
hydraulic
main control lever
(2).
3.
Use
the adjustable
slop
(3) to
maintain
this position.
FLOW CONTROL
VALVE
(Figure B1)
The flow control valve regulates the lifting
speed
of
the 3-point linkage or
remote control cylinders.
A
fast flow,
marked as
'F'
on
the control
knob
(4),
provides quicker corrections and
transfers
maximum
weight
to the tractor
for
increased wheel
adhesion.
Slow settings, achieved
by
turning the
Knob towards
'S',
reduce the
speed
of
corrections
and under
certain
conditions improves the
rale
and
quality of
work, particularly
in
hard
soils.
When
operating
in
a
slow setting
an
internal
linkage temporarily over-rides
the
slow setting
when
the
implement
is
raised.
