Hydraulic Fold System
2411AFG-2411-07-09
1. Models 2411AFG-07-09 Weatherproofer 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.
3. To charge the system, carefully hitch the
Weatherproofer 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 and BASE ends of the fold cylinders to
prevent uncontrolled falling of wing frames when
unfolding. Removal or improper assembly of these
restrictors can cause the machine to fold/unfold
improperly and result in serious machine damage.
WARNING
5. The hydraulic fold system has an automatic wing lock
cylinder in the system
See Figure 4-4 . This small
cylinder is in the center of the machine and will work
opposite of the wing fold cylinders. Verify that when
the wing fold cylinders are retracting that this 1-1/2”
bore x 1-1/2” stroke cylinder is extending.
6. To fold/unfold the Weatherproofer, find a level area
large enough to accommodate the machine when it is
fully unfolded. The tractor should be stopped and not
moving with the unit fully raised. The disc gangs
should also be fully raised to allow more clearance in
the center allowing the blades to stay above the
ground when folding.
7. Slowly engage the tractor lever and fold the wing
frames. The wings should fold fairly evenly and the
wing transport lock hooks in the center will be rotated
to the bottom of the slots, and will allow the wing to
raise them up as it comes over center to hook on the
wing transport lock pin.
8. To unfold, slowly engage the tractor lever and the
wing transport lock hooks should immediately rise up
off of the wing transport lock pins on both left and right
side wings. Continue to hold the lever to allow the
wings to unfold and the wing fold cylinders to fully
extend. The transport lock hooks will remain up until
the unit is folded back up. The wing fold cylinders will
remain fully extended to keep the wings level to the
center frame. If the wings do not appear flat to the
center frame, the wing fold cylinders have wrench
flats on the end of the rod and are adjustable to level
out the wings. Cylinder pressure will need to be
relieved to turn the rod. Adjust both front and rear fold
cylinders the same.
Escaping hydraulic fluid can cause serious
personnel 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 4-2 . Keep all components (cylinders,
hoses, fittings, etc.) in good repair.
