The V451R can produce bales up to 1.60-m (5.2-ft) diameter with a 1.21-m (4-ft) bale chamber width. The MaxD – maximum density – bale chamber has been designed to deliver very heavy, dense, and perfectly shaped bales, officially proven by DLG.
Wide endless belts provide density and reduce crop loss
Only two belts - advanced belt tracking allows the operator to work in all conditions
The V451R Round Baler features two wide 573-mm (22.56-in.) belts, meaning that only three free spaces are observed (one between the two belts plus one on each belt side). Using two belts optimizes bale coverage by approximately 4 percent. The result is significant crop loss limitation and more efficient baling process.
In order to handle huge stress transmitted by the density arm, the belts have no lacers.
An advanced belt tracking system, including wide front pulleys and several guides located throughout the chamber, ensures accurate belt positioning, even when working in slopes or when overloading one pickup side. All edges of parts potentially in contact with the belts are chamfered to avoid belt side damage. A take-up arm manages belt tension compensation during the unloading process to avoid potential belt tracking issues.
Belts are driven by two large-diameter rubber rolls with a large contact surface that avoid belt slippage in very wet conditions. Springs linked to the density arm are located on both chamber sides and give enough tension to the belts from bale starting.
To limit crops from sticking, belts feature a smooth pattern. Paddles on the belts’ driving rolls, cleaning augers into the density arm, and other scrapers located in several places through the belts’ paths continuously clean the belts and remove crop accumulation around the bale chamber.
Standard softcore system provides perfect crop quality
Softcore fully adjustable from monitor
The V451R and V461R both benefit from a standard advanced softcore system management:
- Bale core density (different from the overall bale density) can be adjusted from 0 to 100 percent of maximum density capacity from the monitor.
- Bale core diameter can be set from the monitor.
- Softcore system can be activated/deactivated from the display.
Accurate softcore settings allow:
- Production of better-quality forage when harvesting crops with residual moisture.
- To easily unroll core of bales.

Offset density arm provides tension to the belts
Offset density arm gives tension to the belts
The V451R density is provided by an offset tension arm that applies hydraulic tension to the belts and not directly to the bale. This heavy-duty component is not involved in belt length compensation, so 100 percent of hydraulic power is involved in belt tensioning.
Density is easily set from the monitor and can be adjusted from 0 to 100 percent of hydraulic pressure. A virtual gauge located on the working page continuously follows the density increase without looking back to the baler.
Density can also be adjusted manually from the hydraulic valve in case of major failure.
Bale chamber rolls make easy bale starting in all conditions
Driven bale chamber rolls rotate crops immediately
MaxD bale chamber features three powered rolls to improve versatility and bale quality:
- The three powered rolls facilitate bale starting, especially in wet conditions such as silage. Forage is immediately turning into the chamber and there is no slipping risk even with the heaviest bales.
- Rolls are positioned to give the bale a perfectly round shape, regardless of the bale diameter, and the core is ideally centered.
- As belts push crops against rigid steel rolls, high pressure is easily applied and provides high-density bales.
Heavy-duty components team high density and durability
Reinforced bale chamber components
Heavy bales, high density, high baling speed, and high tractor power directly impacts baler durability. The R-Series Round Balers include several heavy-duty components in the bale chamber to meet long lifetime expectations:
- The front part of the bale chamber (front side sheets) – the most stressed area – is made with Hardox® steel plates to limit impact of aggressive crop friction.
- Lower Fast Release System (FRS) roll handling a large part of bale weight features extra thickness (plus 40 percent versus standard rolls) for extended durability.
- Tailgate frame is specially reinforced around the lock to handle huge tension.
- Top belts driving roll receive a special heat tempering.
