OPERATION AND MAINTENANCE

4-5

Hydraulic Fold System

1.

The VT Plus is equipped with a hydraulic fold system
to raise and lower the wing frames for narrow
transport.

2.

Be sure the system is fully charged with hydraulic oil
before attempting to fold/unfold the unit. Air in the
system can allow uncontrolled dropping of the wing
frames causing serious personal injury or machine
damage. The system needs to be charged with oil
initially and any time the system has been opened for
repair such as cylinder, hose, or fitting
replacement/repair.

Figure 4-5: Hydraulic Leak Detection

3.

To charge the system, carefully hitch the VT Plus to
the tractor. Unpin the end(s) of the fold cylinders, and
position them so they can extend and retract without
contacting any frames or other parts. Check the
tractor hydraulic fluid level to make sure it is full of the
manufacturer’s recommended hydraulic fluid.
Connect the cylinder hoses to the tractor and fully
extend and retract the cylinders several times. The
cylinder rod travel should be smooth and positive
when all air has been purged from the system. Due
to large amounts of hydraulic oil required, recheck
the tractor fluid level to make sure it is within proper
operating limits.

4.

The hydraulic fold system is equipped with restrictors
in the rod end of cylinders to prevent uncontrolled
falling of wing frames when unfolding. Removal or
improper assembly of these restrictors can cause the
machine to fold improperly and result in serious
machine damage.



WARNING

d5842a

Escaping hydraulic fluid can cause serious
personal injury. Relieve system pressure before
repairing, adjusting, or disconnecting. Wear
proper hand and eye protection when searching
for leaks. Use cardboard instead of hands (See
Figure 4-5.) Keep all components (cylinders,
hoses, fittings, etc.) in good repair.
