With some discs turning in pairs towards each other and others turning away from each other, it was necessary to redesign the degree of blade overlap to ensure cleanest cuts. For stripeless cuts in light and young crops, we have therefore increased blade overlaps on the discs turning outwards. In addition, the blades turning to the rear are set further apart to encourage a smooth flow of large volumes of crop.
The KRONE developed satellite driveline comprises massive spur gears with up to 66 teeth which transfer the power all the way down to the very last disc. The large-diameter gears rotate at reduced speeds, with a higher number of teeth meshing with the neighbouring gearwheels for even quieter running, ultimate efficiency and maximum longevity. The auxiliary gears drive one disc each and as a result are exposed to only minimum loading.
The wedge-shaped cutterbar offers many height setting options. The spur gears run in massive double bearings, allowing the cutterbar to handle extremely high loads.
The KRONE SafeCut System
Colliding discs may cause damage and involve costly repairs. KRONE SafeCut offers a maximum of protection and peace of mind. The award winning system on all EasyCut models offers a unique level of protection and operator comfort. SafeCut is a base speciﬁcation feature on all EasyCut F and R models.
Each disc on the mower has its own individual impact protection. When the blade hits an obstacle the shockload is transferred to a roll pin which breaks. As a result, the disc automatically threads 15 mm up on the drive shaft.
If the system is suddenly overloaded, the impact is not directed to the spur gears in the driveline, instead a roll pin in the sprocket drive shaft shears off. The pinion shaft continues spinning, jacking up the disc in question, moving it out of the risk zone and the orbit of the neighbouring discs. As a result, SafeCut prevents damage to the spur gears and the neighbouring discs. Replacing the roll pin takes a few minutes and is not very costly.
The arms on the side mowers telescope to provide the best possible overlapping with the front mower for a perfect cut.
The KRONE mower combinations offer professional farmers and contractors the specification and comfort they need: a large work width, an enormous efficiency and compact build, as well as low tractor input, ease of operation and excellent handling – all being true benchmark features for a mower in this class.
Folded into transport position and safely propped by sturdy stands, the 2.95 m wide EasyCut B 750, B 890 and B 970 models require about 3.70 m to 4.00 m in height. In transport, these machines won’t exceed the maximum height of 4 m and yet give a generous 25 cm ground clearance.
The speciality of this feature is the fact that it maintains the pressure inside the reservoirs of the hydro-pneumatic system – courtesy of extra spools and the circuit of the single-acting coupler with free return line. The advantage of this system is that it maintains a uniform suspension of both mowers in undulating terrain and when working at various work widths.
The hydraulic sideshift feature on the side mowers eliminates any striping and maximizes efficiency productivity. The feature is standard speciﬁcation. Cutting straight lines, the machine operates at the maximum width and minimum overlap, whereas larger overlaps and a narrow work width is selected when cutting curved lines. As you operate on the slope, simply retrieve a stored sideshift range to the right or left and avoid drifting and striping.
Double-acting rams inside the mower arms extend and retract the arms on the move to vary the degree of overlap.Double-acting rams inside the mower arms extend and retract the arms on the move to vary the degree of overlap.
The ISOBUS terminal allows operators to telescope the rear mowers hydraulically in and out, either in sync. or independently by up to 40 cm. In addition, the standard-fit terminal adjusts the work width simultaneously on both sides.
The user-friendly control units on EasyCut B 750, B 870, B 890, B 970 und B 1000 allow operators to select transport position, headland and work position by flicking the rocker switches and control each mower separately.
The EasyCut B 870 and B 1000 are two high-capacity mower combinations. They feature leading edge technology and a new styling plus a weight-optimised headstock with hydraulic suspension that helps protect the sward and also attaches to smaller tractors.
