ROLLANT 455 / 454 UNIWRAP

Compacting rich silage places particular demands on technology. The forage must quickly be shaped into highly compact bales in the shortest possible time. A total of 16 extra-strength, freewheeling steel rollers with profiled surfaces speed up the crop flow and compress the harvested crop into firm, stable round bales, even in wet conditions. Eight reinforcing plates flat-welded onto the roller sleeve inside the rollers provide them with the robustness needed for tightly compacted bales. All bearings and drive shafts have been adapted to cope with the high drive power and throughput rate.

The tailgate locking mechanism via the hydraulic cylinder in the 400 range enables the tailgate to adjust 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 procedure is not decelerated or inhibited in any way, facilitating bale diameters of 49 - 53 in (1.25 to 1.35 m).

MAXIMUM PRESSURE SYSTEM (MPS) – for ROLLANT 455 UNIWRAP.

This swivel-mounted three-roller segment in the ROLLANT tailgate provides the additional pressure. The steel-roller baling chamber with the unique MPS guarantees rock-hard bales and high core compaction. At the start of every bale, the three MPS rollers extend into the baling chamber. As the chamber fills up, the rollers are pressed upwards into their final position as the bale expands. The smaller initial chamber size starts the bale turning much sooner, compressing the bale from the core outwards.

MPS PLUS – the hydraulic generation.

ROLLANT 455 / 454 UNIWRAP

Thanks to the bow-shaped layout of the rollers, the bales rotate inside the baling chamber with minimal power and greater speed. The bale pressure can be selected from the cab using the CLAAS COMMUNICATOR, depending on the dampness of the crop. With pressure adjustable from 870 to 1,740 psi (60 to 120 bar), the ROLLANT with MPS PLUS delivers perfectly compacted bales. The new MPS PLUS achieves higher bale density with less tractor power. The result – perfectly round, dense, easy-to-store bales every time.

The bale fill level indicator is unique to fixed chamber balers. A sensor detects the position of the MPS PLUS segment, which changes as the bale size increases. This is indicated visually via the COMMUNICATOR so that the driver knows that the bale is complete in advance, and can adjust the vehicle speed accordingly.

Net-wrapping system: the results speak for themselves.

ROLLANT 455 / 454 UNIWRAP

Forming and wrapping super-tight, well-compacted and easy-to-store bales demands a fully functional net-wrapping system that is simple to use. The new, convenient net-wrapping system from CLAAS is operated via the CLAAS COMMUNICATOR from the comfort of the cab. Following the automatic tying start, the net wrap is guided around the bale at a specific tension. To maintain an optimal degree of tension, depending on the weather, net-wrap quality or quantity of net wrap remaining on the roll, you can actively intervene in the wrapping process using the CLAAS COMMUNICATOR. An electromagnetic brake on the first rubber roller in the ROLLANT 455 stops the net wrap from unrolling and thus creates the ideal net-wrap tension.

The result: perfect bale-edge coverage for each bale size and ideal bale stability.

Variable number of wraps.

You can match the number of wraps to any crop via the control panel directly from the cab.

ROLLANT 455 / 454 UNIWRAP

Exclusive to CLAAS: automatic tailgate opening.

As soon as the bale wrapping procedure is complete, the tailgate is opened automatically and the bale is quickly ejected. This function can also be deactivated if necessary – nothing could be faster or more convenient.

Automatic tying: top-quality bales deserve nothing less.

Twine or net – ROLLANT gives you the choice. The ROLLATEX net wrapping system saves precious time, since the process is fully automated and takes only a matter of seconds. The fully adjustable net guidance system allows the net to be applied tightly along the entire width of the bale, and firmly binds the edges as well.
