With some discs turning in pairs towards each other and others away from each other, it was necessary to redesign the degree of blade overlap to get cleanest cuts. Therefore we increased the overlap between those discs that turn outwards – a modification that leads to stripeless cuts in light and young material. Vice versa, a larger gap between the blades that turn towards each other encourages the smooth flow of large masses to the rear.
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. Revolving at lower speeds, the large-diameter gears always have a number of teeth in mesh at any one time, giving quiet running, ultimate efficiency and maximum longevity. With each of the auxiliary gears driving just one disc, it is exposed to only minimum mechanical strain.
The wedge-shaped cutterbar adjusts through a large setting range to cut short stubble in meadows and pastures and longer stubble in longstemmed field crops. EasyCut cuts blockage-free and clean. Benefitting from massive double spur gear bearings that are spaced at large gaps, the cutterbars are heavy-duty and hardwearing.
• Full driveline protection
• Neighboring discs will not collide
• No wear and damage
• Quick roll pin change, minimum costs
The situation is familiar to every farmer – a disc collides with a foreign object, is damaged and requires repair. Offering a maximum of protection, the Krone SafeCut does not transfer the full shockload to the spur gears. a disc hits a foreign object, gets damaged and needs replacing. In this situation, Krone SafeCut offers a maximum of protection. The DLG Gold winning new disc shear-off system brings a new level of protection and operational reliability to the EasyCut mowers with and without CV conditioner. SafeCut is standard equipment on all EasyCut disc mowers.
Peace of mind:
Instead of transferring the full shockload to the spur gears, the roll pin in the sprocket driveshaft breaks when there is a momentary overload. The pinion shaft continues spinning, jacking up the disc in question and the disc moves out of the risk zone and the orbit of the neighboring discs. This way SafeCut prevents damage to the spur gears and the neighboring discs. Replacing the roll pin takes a few minutes and is not very costly.
Perfect in every detail:
• Huge work widths of up to 9.70 m (31'10")
• Optimal overlap – EasyCut B 890 and B 970 with telescoping arms
• Compact break-back headstock for smoothest ride
• Balancing arm distributes the ground pressure uniformly to both ends
• Mowers of finest engineering: Committed to greatest efficiency in any respect, Krone manufactures mower combinations that stand out for their high performance and ease of pull – an achievement of a robust and • • advanced technology that delivers superior functionality and perfect 7.46 m (24'6") to 9.70 m (31'10") cuts.
The arms on the side mowers telescope to provide the best possible overlapping with the front mower. The combination produces perfect cuts without striping.
A perfect system:
EasyCut B 890 and EasyCut B 970 operators can alter the space between the two side mowers to eliminate striping on slopes and in bends. The standard telescoping arms adjust each wing to overlap up to 45 cm (1'6") with the 3.16 m (10'4.5") front mower. Set up this way, the combination produces cleanest, loss-free cuts in the most difficult terrain. Vice versa, you can set the combination to its maximum span to sweep large fields in flat terrain at staggering rates.
• Operator box for maximum comfort
• Operate the side mowers in synch or individually
• Compact transport dimensions: 4.00 m (13'2") max. transport height, 25 cm (10") ground clearance, 2.95 m (9'8") transport height
Krone mower combinations offer professional farmers and contractors the specification and operator comfort they deserve: A large work width, an enormous efficiency and compact build, as well as a low tractor input, ease of operation and excellent handling are parameters that set new standards in this category.
Nice and compact: Offering 3.70 m (12'2") to 4.00 m (13'2") storage heights and a 2.95 m (9'8") width, EasyCut B 750, B 890 and B 970 require little storage space and are parked on sturdy stands. And despite the generous 25 cm ground clearance the machines transport height does not exceed 4 m (13'2").
