Claas has added the Rollant 520 to its long-established Rollant round baler lineup. The 520 is aimed towards the farmer-scaled market, with three variants offered.

The Rotocut model is fitted with a 14 knife chopping unit, the Rotofeed having a feed rotor and a third variant fitted with an assister feed rake. All models are fitted with a 2.10m pickup, apart from the assister feed rake variant, which is fitted with a 1.85m pickup.

It has 16 rollers. The upper eight rollers are made from 3mm sheet steel, while the lower eight, which carry the majority of the weight, are manufactured from 4mm steel.

Three variants are available with the 14 knife Rotocut model probably best suited to the Irish market.

Power transmission to each roller is performed by a lateral stub shaft on the end of each roller body. Like the rollers themselves, the stub shafts can be replaced individually and bolted on to the new roller. Claas claims this makes roller replacements cheaper than previous one-piece roller types, a construction that has proven its worth on 540 and 620 models.

Rollers are driven on both sides, with main drive and tailgate rotors fitted with Zubakki 1 inch drive chains. An adjustable Eccentric pump draws oil from the 4l chain lube tank on to chains as needed, regardless of throughput.

Bale density is dependant on tailgate rams, as a maximum density pressure of 150 bar can be applied to these rams. An optional MPS II systems allows for three of the compression rollers to pivot into the chamber for additional bale compaction and earlier bale rotation.
