ROLLANT 520
Bales everywhere.

Robustness and reliability under the toughest operating conditions have made the ROLLANT the best-selling silage baler in the world. Reinforced rollers, intelligent chain lubrication, and the optional MAXIMUM PRESSURE SYSTEM II (MPSII) in the tailgate ensure that it stays that way.

MAXIMUM PRESSURE SYSTEM II for the ROLLANT 520.

Three-roller segment with two large, adjustable springs
Excellent value for money for denser bales
Softer or harder bales as needed
Perfect bale shape even in difficult conditions

The steel roller bale chamber with MPS is your guarantee of rock-hard bales with high-core compaction. That’s because of the extra pressure delivered by MPS, the pivoting three-roller segment in the ROLLANT tailgate. At the start of the baling process, the three MPS rollers project into the bale chamber. During the process, the rollers are then pushed up into their end position by the bale as it increases in size.

The benefits for you are that the bale rotates right from the start and is compacted already from a diameter of 35" (90 cm). With the pressure freely adjustable from 870 to 1,740 psi (60 to 120 bar), the end result is perfectly compacted, high-density bales—even at high ground speeds.

High pressure with particularly robust steel rollers.

Crops need to be compacted quickly into high-density bales for quality forage. In the ROLLANT, this happens with highly robust steel rollers with profile webs that ensure an active crop feed. As a result, the crop is pressed into firm, round bales with excellent shape retention even in damp conditions. All bearings and drive shafts are designed for this baler’s high power and throughput.

Hydraulic pressure control.

The locking mechanism via a hydraulic ram enables the tailgate to adjust to and lightly resonate in line with the rising pressure as the bale size increases. The bale is able to rotate at all times, and the baling process is neither slowed down nor inhibited in any way.

Opening and closing in record time.

The double-acting hydraulic rams are highly responsive, ensuring that you can open and close the tailgate extremely speedily from the tractor cab.

The benefits at a glance.

Axle screwed onto the 0.6" (15 mm) thick end plates
Ribbed profile for perfect bale rotation even in wet harvesting conditions
Continuous, laser-welded baling roller walls for increased stability of the baling roller
Forged axle for greater stability
Bale chamber diameter of 49–53" (1.25–1.35 m)

Smooth crop flow.

The cam controlled pick-up adjusts to any ground contours, even at high working speeds and while negotiating curves. Large guide wheels with tool-free adjustment keep you safely on track at all times.

Easy unloading.

Blockages in the intake can be cleared quickly and easily by reversing the rotor mechanically using the rotor lever. The hydraulic rotor unblocking unit—available as an optional extra—can be activated from the cab and allows the baler to be driven right up to its performance limits without any problems.

With a working width of 83" (2.1 m), the pick-up easily captures even very wide swaths.
The ingenious pick-up design and location reduce forage losses and contamination.
The crop flow remains consistent even in curves and at high speeds.
Roller crop press and a baffle plate increase the throughput even further.

Maximum crop flow output: ROTO FEED.

The feed rotor's rotor blades are arranged in dynamic helixes to ensure uniform intake and efficient throughput. The system is particularly well-suited to delicate types of forage, such as alfalfa. The helical arrangement protects crops and produces top-quality forage.

How much power would you like?

ROTO CUT—a fine 2.75" (70 mm) cut.

The ROTO CUT feed system runs at over 7,000 chops per minute. Four rows of tines gather in the crop evenly through the knives. The crop is guided precisely over the center of the blades and chopped exactly. A special system of strippers keeps the rotor clean at all times. The precise angle of the feed tines effectively prevents the crushing of the crop as it passes through. Uniformly chopped slices improve silage quality and facilitate easy distribution both in silage preparation and later on in the feed mixer.

Tying.

In great shape with the new net wrapping.

Whether twine or net, the ROLLANT 520 will ensure you get everything right. The new net wrapping system works more reliably than ever and saves a lot of time. Wrapping is fully automatic and takes only a few seconds. The sophisticated net guide allows the net to be applied tightly across the full bale width and firmly secures the edges as well. The result is firmly wrapped bales with a good bale shape.

Changing rolls is a breeze.

If you wrap your bales with a net or film, you need to handle heavy rolls. However, with the ROLLANT's convenient loading bay, changing rolls is a breeze.

Your alternative—twine tying.

When twine tying, you have a choice of manual or automatic twine start. The automatic system starts the process once the set final pressure is reached, and the operator receives a visual and acoustic alert.

Constant chain lubrication.

The new distribution units in the 1.66 gallon (6.3 liter) lubricator supply each individual chain with exactly the amount of oil needed for long and smooth-running operation. You can save on cash, in addition to saving valuable maintenance time.

Modern design.

The proven ROLLANT fixed-chamber concept is subject to continuous development and improvement by our engineers. The new generation has revised the design completely. One glance at the new lines makes it clear that this is one of the most robust balers in the world.
