Productive: new pick-up and hydraulic knife group activation

In 1934 CLAAS revolutionised forage harvesting with the introduction of the PICK-UP baler with tined drum to gather the crop. The basic principle was ground-breaking at the time and is still being systematically refined to this day. The latest generation pick-up, the CLAAS Multiflow with 2.10 m working width (1.90m DIN raking width), is designed to even further reduce crop losses and ensure more uniform material crop flow in the ROLLANT 630 RC UNIWRAP. The standard pick-up is equipped with five cam-controlled tine bars. The new cam track reduces the power requirement by 20 percent. Removable strips made from special plastic guarantee rapid and easy access for maintenance work.

The pick-up transfers the crop to the tried and tested heavy-duty ROTO CUT cutting rotor with 8 mm double tines made from double-hardened boron steel arranged in a helical formation. Four rows of tines feed the crop at up to 13,800 cuts per minute optionally through the 25-knife cutter bar with a 44 mm cut length. The knife groups (25/13/12/0) can be activated electrohydraulically from the comfort of the cab. All knives are individually secured and can be hydraulically engaged or retracted centrally.

The PRO cutting floor can be lowered by up to 30 mm to adjust the crop flow and prevent blockages in uneven swaths. An optical and acoustic early warning system additionally enables the driver to operate as close to maximum baler capacity and to reduce the ground speed when the forage volume increases significantly. Should a blockage nevertheless occur, the cutting floor can be lowered hydraulically by pressing a button on the control terminal.

Durable: solid drive, chassis and tailgate suspension

The drive chains have been substantially reinforced in the areas subject to the greatest wear. The chain links there are both longer and stronger. Together with larger gears, this reduces wear on the chains. Guides on either side of the chain-tensioning wheels also reduce wear by preventing the chain from slipping or shifting. The size of the oil container for chain lubrication has been increased to 7.2 l, providing an ample supply of oil for a long service life in all operating conditions. And since the lubrication system supplies each individual chain with exactly the amount of oil needed, no oil is wasted. This protects the environment and guarantees efficient operation – for up to 14 hours, without having to be refilled.

The new central lubrication system is also designed for demanding and variable harvesting conditions. In addition to the familiar central lubrication system, an enhanced PLUS central lubrication system which greases the complete wrapping table is optionally available. This cuts maintenance time by a further 10 minutes.

To give the chassis more stability, especially in extreme harvesting conditions, tried and tested technology from the QUADRANT square balers has been used in areas subject to the greatest wear. The thickness of the steel profiles has been increased by 20 percent to provide the ruggedness and durability to withstand extreme conditions such as a those associated with very wet crops.
