Claas unveils new entry level Rollant round baler

Class has introduced a new entry-level fixed chamber round baler for use behind lower horsepower tractors.

The Rollant 520 produces a 1.25m diameter bale, which is made using a new 16-roller set up, eight of which are made from 3mm-thick steel sheet and the remainder 4mm-thick sheets.

The ribbed profile of the rollers is said to ensure precise rotation of the bale, even in moist conditions.

Taken from the 540 and 620 models, storage and power transmission to each roller is now performed by lateral stub shafts flanged on to the roller bodies. These can be individually replaced if necessary, like the rollers themselves.

Rollers are driven from both sides and the rotor, main drive and tailgate rollers are fitted with Zubakki 1in drive chains.

Improved lube system

The chain lubrication system pumps oil out of a 4-litre tank via an adjustable pump and as lubrication is not tied to throughput, oil is distributed when and where it is needed on the chain link pivot points.

Baling pressure is controlled by tailgate closing rams and for maximum bale density, up to 150bar can be applied to the rams.

An optional MPS II system sees three of the compression rollers able to pivot into the chamber to provide addition bale compaction, early bale rotation and a more uniform bale shape, say Claas.

Intake rotor options

The Rollant 520 is available in three different variations. One has a 14-blade Rotocut chopping system, the second a Rotofeed feed rotor, and finally a Rotofeed with an assister feed rake.

Crop is picked up with a 2.1m controlled pick up, which is a slightly narrower 1.85m when opting for the assister feed rake option.

An optional crop guard improves crop flow and helps with a uniform bale shape, while two lateral feed augers manage the flow of material to the intake rotor.

Operators can choose between net and twine wrapping modes without the need for tools and a neat feature sees a ramp on the side of the machine to ease the process of changing film or net.
