CLAAS presents its new range of variable round balers

With the introduction of the VARIANT 400 series, CLAAS presents a new range of variable round balers. The main focus of development work has been crop flow, but intake, wrapping and maintenance have also been improved, meaning that the balers are now more powerful, reliable and easier to use when harvesting straw, silage and hay.


The new VARIANT 400 series will replace the existing VARIANT 300 range from the 2017 harvesting season. As before, the new range will be available in two different bale sizes (0.90–1.55 x 1.20m and 0.90–1.80 x 1.20 m) as well as with (ROTO CUT) or without the cutterbar (ROTO FEED). There is also the option for the PRO cutting floor with hydropneumatic suspension as well as the XXL pick-up with a width of 2.35 m.

Optional dual roller crop press

A dual roller crop press, the same as that fitted to the QUADRANT square baler and the JAGUAR forage harvester, is now also available for the pick-up. The dual roller crop press is suspended and can be mechanically switched between four different settings without the use of tools. It allows the intake to be quickly adjusted to suit different operating conditions and ensures a more uniform and faster crop flow, meaning that the new VARIANT models can be driven at higher operating speeds. In the case of the PRO version, the cutting floor automatically drops when there is a risk of blockage, meaning that the baler can always be driven at its optimal level of performance.

In addition, the two oscillating castor guide wheels that steer the pick-up along the ground have been reinforced and can now be folded when using the XXL pick-up to reduce the transport width.

360-degree rotor star structure

Improvements have been made to the new models' star rotor structure. The star rotor now turns through 360 degrees instead of the current 180 degrees. The new star rotor structure uses 14 knives, reaching a rate of 6,000 cuts per minute, thereby ensuring that the flow of material is widely distributed when it is fed into the bale chamber, which results in uniformly shaped bales. This is an advantage particularly in the case of narrow swaths.

New net wrapping

The new models' system for the intake of net or twine has also received an overhaul. A new plate assists with the insertion of netting or twine into the baling chamber, which means that you can be sure that the tying process will start properly under all harvesting conditions.

The new VARIANT models come equipped with edge-to-edge net wrapping as standard, which stretches from one corner of the bale to another. This has been improved for the new range by actively taking the netting to the outer edges of the bale during the tying process with the help of a new spiral roller.

There is also the option for the VARIANT 400 to be equipped with a wider netting trough. This enables the use of 1.30 m wide rolls of netting, which will lay the netting over the edges of the bale. Rounded bale edges are of particular advantage if round bales are to be stored outside.

Chains and belts live longer

The front frame of the new VARIANT 400 has been reinforced so that the belt is better guided which will reduce wear. Nevertheless, inside the VARIANT the belts still move at a speed of up to 3 m/s.

When it comes to discharging the bales, this also takes just a matter of seconds. CLAAS has redesigned the pivot of the tailgate in such a way that it can be opened and closed even more quickly, allowing the bales to be discharged in less than 6 seconds.

The baler's chains are subjected to just as much wear as the belts. This is why the new VARIANT models come with the option of continuous lubrication by means of a central lubrication system. The balers have been fitted with a wide lubricating brush, which coats all chains, including the pick-up chain, with oil, regardless of the bale count.
