PROBLEM
POSSIBLE CAUSE
POSSIBLE REMEDY
OUTER SHANKS ON
ARE CUTTING TOO
DEEP
-
All three wheels on
are too high
causing ends of wing to drop
-
Raise end of
by adjusting anchor bolt of
outer wing lift cylinder. See Section
1
of
Adjustments on page 10.
OUTER SHANKS ON
ARE NOT CUTTING
DEEP ENOUGH
-
All three
on
are too low
lifting ends of
out of ground
-
Lower end of
by
anchor bolt of
outer wing lift cylinder.
See Section
1 of
Adjustments on page 10
.
FRONT SHANKS ARE CUTTING DEEPER THAN
REAR
-
Front castor wheels are too high causing
front of cultivator to drop
-
Raise front of cultivator by lengthening castor
wheel links. See Section
2
of Adjustments on
page
10.
REAR SHANKS ARE CUTTING DEEPER THAN
SHANKS
-
Front castor wheels are too low causing
front of cultivator to lift
-
Lower front of cultivator by lengthening castor
wheel links. See Section
2 of Adjustments on
page 10.
AND
FRAMES DO NOT LOWER INTO
GROUND EVENLY
-
Rockshafts and castor wheel linkage is
tight or seized
-
Lubricate rockshaft bearings, linkage, ball joints
and castor wheel pivot points.
DOES NOT PULL STRAIGHT.
CULTIVATOR SKEWS TO THE LEFT HAND SlDE
OR RIGHT
-
One wing is cutting deeper than the other
-
One side of cultivator is cultivating hard
ground
-
Level wings
-
Cultivator will pull straight when soil condition is
the same across full width of cultivator
SHANKS ON ONE SlDE OF CENTRE SECTION CUT
DEEPER
THE OPPOSITE
Low tire pressure on one set of centre
section tires
-
Centre section rockshaft may have been
twisted causing wheel leg to be lower
than other one
Equalize tire pressure on all
tires
-
Centre section rockshaft must be untwisted so
wheels are at same angle or rockshaft must be
replaced
NOT FLEX
-
Wings are hanging up on the wing lift
cylinders because they are not fully
extended
-
Fully extend wing lift cylinders
CYLINDERS
RAISE WINGS
-
Tractors'
pressure is too low
-
A piston seal in one of the wing lift
cylinders has been damaged allowing
hydraulic oil to bypass
-
Increase tractors' hydraulic pressure, consult
your tractor dealer
-
Replace piston seal in one of the cylinders
ROCKSHAFT CYLINDERS WlLL NOT
CULTIVATOR OUT OF GROUND
-
Tractors' hydraulic pressure is too low
-
A piston seal has been damaged allowing
hydraulic oil to bypass
-
lncrease tractors' hydraulic pressure, consult
your tractor dealer
-
Replace piston seals
WHEN RAISING CULTIVATOR OUT OF GROUND,
