RBA
ROUND BALE UNROLLER
The round bale unroller RBA is the ideal solution for fast, clean, and effortless fodder distribution.
Whether used for silage, hay or straw, the device opens the bale completely and without losing any fodder.
The device allows for both stationary and mobile operation. During mobile use, the fodder is distributed directly at the feeding table.

IMAGE DESCRIPTION
1) The first step requires that the upper half of the film and net be removed from the bale.
2) Next, the bale is loaded onto the RBA with a loading arm or an external device.
3) The second half of the film and net can be removed once the bale has been turned.
The fodder is ready to be distributed.
4) The bale is opened completely and uniformly.
FUNCTIONAL DESCRIPTION
Aided by the scraper floor the bale is pressed onto the elastic spring tines and
then placed in rotary movement. The fodder is unrolled completely and evenly and can
be deposited directly at the feeding table.
The device can be tailored to specific needs thanks to extensive additional equipment
options.
Whether tightly compressed, short, long, cut or uncut, the fodder is always split without a
hitch

VARIABLE ATTACHMENT SYSTEM
The variable attachment system makes it possible to spread the fodder from three
directions simply by changing the position of the hydraulic hoses.

Hydraulic loading arm
The hydraulic loading arm picks the bales up in a snap. This eliminates the need for
an additional vehicle. Mounting the loading arm on the other side only requires a few
simple steps.
Electric drive
This drive makes it possible to use the round bale unroller as a stationary unit as well.
Radio remote control
A compact operating unit with radio control offers a convenient way to control the RBA
both from the tractor and from outside the tractor. The associated control device is
mounted on the RBA.
For operation with a wheel loader or telescopic loader, a single-acting control device
with free return, as well as a 12-volt connection are required.
Manual control valve
The manual control valve allows the operator to control the bale opening device from
the tractor cab.

The round bale cutter offers a convenient way to cut open and split bales. The round bale is placed on the five reinforced tines and cut all
the way through by a knife bar. The serrated shape of the knife guarantees a safe and robust cut. Multiple cuts ensure that the fodder can be
distributed directly at the feeding table.

IMAGE DESCRIPTION
1) The round bale is picked up.
2) The eight hooks of the film holder keep the film in place.
3) The film is cut.
4) The fodder is cut separately from the film and the net.
5) While the silage is being split, the film holder keeps film and net firmly in place.
6) The film is cleanly separated from the fodder and can be disposed of afterwards.
DETAILS OF ADDITIONAL EQUIPMENT OPTIONS
Film holder
The film holder allows the operator to cleanly separate film and net from the fodder without
the hassle of having to step down from the tractor. Eight hooks hold film and net safely in
place while the bale is being cut through.
This saves the operator the trouble of removing the film manually beforehand.
Operation is controlled using a double-acting control device.
