New Holland Roll-Belt™ Round Balers - Roll-Belt™ 450

The Roll-Belt™ design utilizes heavy-duty steel rolls in the front of the baler and in the floor of the bale chamber. These rolls are combined with short, tough belts in the back to deliver fast, consistent core formation and tight, uniform bales regardless of the crop you’re baling. Saving you both time and money, this proven combination packs more of your valuable crop into each bale to form some of the densest bales in the industry.

1 – To deliver fast, consistent core starts and support the bale as it grows, the floor roll moves crop from the feeding system up into the chamber. This roll carries most of the bale’s weight to reduce stress on the belts and lacings for longer life and lower maintenance costs. From here, belts carry crop up into the sledge frame rollers.
2 – The core begins when the stripper roll turns the hay downwards, moving it into a D-shaped core in the chamber. To allow for full-diameter bales, the completed core rotates this roll forward.
3 – The pivot roll acts as the pivot for the stripper roll above and its dimpled surface helps move crop to the fixed roll below. The gap between the pivot roll and the fixed roll allows net wrap to be applied from the front of the baler.
4 – The fixed roll has slats to keep the hay rolling, turning it back towards the belts to complete the core.
5 – The starter roll below the fixed roll supports the core in the chamber. Its smooth surface eliminates interference as crop is turned towards the belts.
6 – To maintain belt pressure as the bale grows, the take-up arm assembly moves to expand the chamber.

For superior bale shape and density, a hydraulic valve creates pressure to tension the belts that manage bale density. When equipped with manual density controls, you can make simple adjustments on the density cylinder and monitor density with the convenient sight gauge mounted near the front of the baler. To save time when moving from dry grass to heavy, wet silage, in-cab density controls are also available that allow you to adjust density on-the-go with the monitor. For rock-hard bales, an in-cab HD density system is offered to equip a baler with twin cylinders for 5% greater density than the single cylinder system.

For a sure grip and gentle handling, these seven-inch wide belts provide 90% surface contact across the full bale to reduce crop loss. Roll-Belt 450 Utility PLUS and Hay Special balers are equipped with standard Clipper® fasteners and pin lacing, while 460 Hay Specials can be upgraded to a premium MATO, high-strength fastener and pin lacing.

For ultimate durability and low maintenance, premium endless belts are standard on all non-Hay Special balers and optional on Specialty Crop balers. Since these belts are splice-free, they require zero lacing maintenance. Their sealed-edge construction enhances side-to-side rigidity, reduces tearing, and prevents edge fraying. The self-cleaning surface pattern is designed to release crop material and deliver a firm yet gentle grip. These belts are so dependable, they are backed by a three-year or 15,000 bale New Holland factory warranty.
