3-Point Hitch System Problems
Problem
Possible Cause
Corrective Action
Engine speed is too low.
Increase engine speed.
Hitch components are binding, worn or
damaged.
Inspect hitch components and repair or
replace if necessary.
The hydraulic fluid level in the hydraulic
tank is low (other hydraulic circuit
performance is affected as well).
Adjust the hydraulic fluid level.
Relief valve (RV2) in the main manifold
is stuck, leaking or damaged.
Clean the relief valve and replace the
seals.
An electrical problem exists in the
proportional solenoid valve (SP1)
circuit.
Test and replace the valve solenoid if
necessary.
Test the machine wire harness
proportional solenoid valve (SP1)
circuit.
Proportional solenoid valve (SP1) in the
main manifold is stuck, leaking or faulty.
Clean the solenoid valve and replace
the seals.
Replace the solenoid valve if necessary.
Hitch cylinder circuit pressure is low
(traction charge and steering circuits
affected as well).
Verify charge pressure; refer to the
InfoCenter SERVICE–INPUT/OUTPUT
–TRACTION–TRACTION INPUTS
FRONT TRACTION and REAR
TRACTION readings while the machine
is stationary.
Hitch cylinders will not raise or raise
slowly.
Verify gear pump (P4) performance;
refer to Gear Pump (P4) Flow Text in
the Hydraulic System chapter of this
manual
Proportional solenoid valve (SP1),
(SP2), or check valve (CV2) in the main
manifold is stuck, leaking or faulty.
Clean the valve(s) and replace the
seals.
Replace the valve(s) if necessary.
Hitch cylinders raise but will not stay up.
NOTE:
Hitch cylinders cannot provide
an absolutely perfect seal. The lift arms
will eventually lower if left supporting
an attachment in the raised position
during storage.
A hitch cylinder is leaking internally.
Test and repair or replace the hitch
cylinder if necessary.
An electrical problem exists in the
proportional solenoid valve (SP2)
circuit.
Test and replace the valve solenoid if
necessary.
Test the machine wire harness
proportional solenoid valve (SP2)
circuit.
Proportional solenoid valve (SP2) in the
main manifold is stuck, leaking or faulty.
Clean the solenoid valve and replace
the seals.
Hitch cylinders will not lower.
Replace the solenoid valve if necessary.
The hydraulic fluid level in the hydraulic
tank is low (other hydraulic circuit
performance is affected as well).
Adjust the hydraulic fluid level.
Gear pumps (P3 and P4) are noisy
from cavitation (steering, traction
charge, lift circuit and attachment circuit
performance is affected).
The suction filter or suction line is
damaged, loose, or clogged.
Secure, clean or replace the suction
filter or suction line.
