Claas ROLLANT 520

Lubrication of the drive chains occurs automatically with the standard centralized chain lubrication. A simple cam adjusts how often oil is set to the drive chains completely independently of how often the tailgate is cycled. This extends the service life and keeps wear as low as possible even in low-yielding crops. 1.7 gallon (6.3 L) capacity handles long working days without needing refills.

MAXIMUM PRESSURE SYSTEM (MPS) is optionally available for the ROLLANT 520. The three-roller segment pivots in the tailgate, generating additional pressure on the bale when it reaches 41" (1.05 m) in diameter. Perfectly formed, highly compacted bales are made even at high groundspeeds.

16 rollers are used to spin the crop for particularly dense silage bales. 8 of the rollers have 3mm thick sidewalls with the other 8 rollers having thicker 4mm sidewalls for added strength. This extra material allows bale densities to be higher than ever without damaging the baler and more bale density equals fewer bales to handle, less fuel, less labor, less net wrap, and less depreciation used per year. Rollers are held in place by a bolted shaft flange that provides greater elasticity where welded shafts would crack from vibration stress.

After opening the tailgate and dropping the bale, a bale ramp makes sure the bale has cleared before the tailgate is closed. A position sensor indicates in the cab to the operator when the tailgate can be closed and baling resumed. This prevents potential damage to the machine but also saves time and wear on the tractor that is typical when reversing to drop a completed bale. With the ramp, reversing is not required and is a CLAAS exclusive in the fixed chamber market.
