Farm equipment manufacturer CLAAS has introduced a new fixed-chamber ROLLANT 520 round baler that features a “contemporary visual design” to go along with a new oil-chain-lubrication system, new optional MPS (Maximum Pressure System) II tailgate system, 16 reinforced rollers, and more. With the ROLLANT 520—which assumes an entry-level position in CLAAS’ 1.25-metre segment and combines all the benefits of the company’s previous ROLLANT 340 and 350 models—CLAAS claims it's “embarking on a new chapter in the 43-year ROLLANT success story.”
Clean, Efficient & Reliable
Operated via a CLAAS OPERATOR terminal, the ROLLANT 520 produces 1.25-metre diameter round bales measuring 1.2 metres wide. CLAAS offers the baler in 520R (with assister feed rake), 520RF (ROTOFEED model with feed rotor), and 520RC (ROTOCUT chopping system) variants. CLAAS says the balers’ 2.10-metre-wide controlled pickup (1.85-metre pickup with the assister feed rake) handles crop pickup “cleanly and efficiently,” and says the two lateral feed augers convey material to the intake rotor “efficiently and reliably.”

Another noteworthy design feature is the ROLLANT 520’s use of 16 reinforced, wear-resistant, and replaceable rollers, including eight rollers that CLAAS constructs from 3-millimetre-thick sheet steel and eight using 4-millimetre-thick sheet steel. All the rollers possess a ribbed profile that CLAAS says ensures “precise rotation of the bale, even under moist conditions.” Elsewhere, in addition to noting the baler’s rollers are driven on both sides, CLAAS says the rotor, main drive, and tailgate rollers are equipped with 2.5-centimetre drive chains.
Additionally, the baler features a 4-litre oil tank with adjustable eccentric pump that automatically distributes lubricating oil as needed directly to the chain link pivot points. The baler’s intelligent chain lubrication system also automatically adjusts the tension of the drive chains. Finally, baling pressure is applied by the baler’s tailgate closing rams, which can apply up to 150 bar for maximum bale density; CLAAS also offers an optional MPS II system consisting of three compression rollers that pivot into the baling chamber for added compaction, which results in “rock-hard bales,” early bale rotation, and uniform bale shapes, the firm says.
