The new EasyCut B 970 mower
Easy in handling, convenient in use

Spelle, 21 September 2011 – For Agritechnica 2011, Krone is presenting a new generation of butterfly mowers. The new Krone EasyCut B 970 butterfly combination stands out for its unique ease of use and adjustable work width of up to 9.65 m. The two butterfly units at the rear use a pin and hole setting system that shifts them up to 15 cm to either side to obtain the best possible overlap when working on side slopes or cutting around corners. Back in flat fields, the operator resets the combination to its full work width. Further comfort features on the rear units include a spring suspension system that uses a patented pivoting arm to adjust the ground pressure easily and provide optimum flotation in hilly terrain as well and good balance independent of the tractor.  In addition, the new rear mowers feature an intelligent break-back system, which allows them to move back and up when hitting an obstacle, such as a stone or fence, and automatically move back into working position once they passed the obstacle.

Easy transport is another stand-out feature of this combination. Both mowers swing in line behind the tractor, with the top ends inclined toward each other to give a 2.5m transport width at the top for improved rides  and reduced risk of the rig fouling overhanging branches. Its transport height is less than 4 m the machine and the machine hovers over the ground at a 25 cm clearance. Further practical details include the heavy-duty stands, which allow storing the folded mower in a simple, fast and compact way. The transport and storage width is less than 3 m.

The front mower is a well-proven and push type unit with spring suspension. The new design brings the unit closer to the tractor for reduced wear on mower and tractor. It also offers easy attachment and no bouncing when travelling at speed. Krone is marketing adjustable link arm adapters to go on linkages with rigid link arms.
The comfort features aside, Krone also uses well-proven EasyCut technology for the mowing process itself. The flat V-shaped cutterbar gives exemplary flotation.  In addition, the EasyCut mowers are simple and straightforward by design and use only few moving parts, which translates into reduced wear and lighter weight. Quick-fit knives are standard specification. In addition, EasyCut B 970 boasts the innovative and patented SafeCut mower bed, which offers a unique impact damage protection system. The system centres on a roll pin that connects each disc to the drive shaft and that shears off as the disc hits an obstacle. Upon impact, the sprocket continues revolving, so that the stopped disc jacks up on a thread and out of the operating area of its neighbouring blades, eliminating the risk of damage to the neighbouring discs.
Another practical feature is a box that stores spare blades. The box is integrated in the frame for operator convenience.
