New Claas balers prepare for action

Bruce Lett

Making their working debut at this year's FTMTA Grass & Muck event are Claas's Quadrant 3300 square baler and Rollant 374 and 375 balers.

Having successfully run pre-series machines last year, the new balers are now available and visitors to Gurteen will get to see them in the flesh.

According to Claas, the new Rollant fixed chamber round balers are designed to cope with the heavy crop conditions typically found in Ireland and Britain.

A total of three new models will be available, the 374 RF (roto-feed), 374 RC and 375 RC.

These balers are based on the Rollant 355 and 354 but feature heavier duty drives and stronger, long-life chains.

The baling chamber on all models features 16 heavy-duty, reinforced rollers and a hydraulic drop-floor below the bale chamber to clear blockages if they occur.

From the 2.1m wide pick-up, material is fed into the chamber either via a roto-feed (RF) star rotor (non-chopping) or the 16-blade roto-cut (RC) chopping cylinder.

For increased density, the 375 also features a new pressure system, where three rollers in the chamber swing down to exert pressure on the bale in the early stages of formation.

Claas claims this system gives a 20pc increase in bale density and makes a tight bale to maintain its shape during storage.

The hydraulic drop-floor is operated via a double-acting valve that allows the floor to open slightly during baling to allow smaller lumps to pass through without causing a blockage. At the same time the operator is notified via a buzzer, so they know they are working at maximum throughput.

If a blockage does occur, the operator lowers the drop floor at the press of a button.

Re-engaging the pto clears the blockage, after which the drop-floor automatically closes. To help reduce the risk of blockages before they can occur, the pick-up is fitted with a double-roller crop press to smooth material flow into the pickup and rotor.

On RC models the chopping system features 16 spring-loaded, hardened steel blades which give a theoretical chop length of 70mm.

The balers come with the new generation II CMT control unit fitted as standard.
