4 Description of the wrapped bale handler
The wrapped bale handler is suitable for loading foil-wrapped silage bales. Of
course, even highly compressed bales of all standard shapes and sizes that are
not wrapped can also be loaded. The bales gripped with tongs must not be
transported on public land.
4.1 Construction
The grippers of the bale tongs are each mounted with a pivot pin (1) on the frame.
The two hydraulic cylinders are each mounted with a pivot pin (2) on the gripper
and in the middle of the frame (3).
The tongs are opened or closed by means of the cylinder controlled by the tractor’s
hydraulic system.
The maximum permissible load is 1,100 kg and the maximum opening width is 130
cm.

16 P 1548 EN13 RE 01
4.2 General information
•Compress the silage bales as tightly as possible to improve their
transportability.
•Press the bales, which have secondary fermentation and are very soft,
repeatedly together with the tongs before transporting them, as these bales are
too prone to collapsing and can slip out of the tongs if the drive is a particularly
bumpy one.
•Make sure that the bale is on the inside of the support frame when gripping and
transporting it, because this guarantees the safe handling of the bale.
•Always wrap the bales in the area of the final storage location. The delicately
wrapped bales can be damaged after longer trips.
•You can pick up, transport, set down or stack the foil-wrapped bales with bale
handler both in the upright and horizontal position.
•For a secure hold, grip the bales at the bottom, see picture below.
•Close the bale handler completely for road travel, the vehicle then shifts around
less.
4.3 Startup
Follow the operating instructions of the front loader!
Before the first startup check that all the screw connections are tight!
The factory assembles the bale handler so that it is ready for use. Only the two
hydraulic connections are sealed with plastic caps and the supply lines are
enclosed in a bag.

P 1548 EN13 RE 01 17
Mount the supply lines
•Remove the two plastic caps on the hydraulic cylinder and turn the screw
socket firmly into place.
•Then screw on the two hydraulic hoses as shown in the figure with the
mounting boss and attach the coupling sleeves onto them at the other end.
•Attach the red cap on the coupling sleeve on the upper hose ("Open" function)
and the black cap on the lower hose ("Gripping" function).
•Finally, bundle the individual hoses together with the aid of cable ties.
Mounting of the front loader rocker
•Mount the quick-change frame under the hook of the bale handler.
•Then lock this in place by tilting the quick-change frame.
Connect the hydraulics
•Connect the hydraulic hoses for the drive of the bale handler to the terminals of
the front loader’s 3rd control circuit.
•Check that it works properly. To do this, open and close the bale handler
several times.
