The cutterbar features a host of smart details like the SafeCut disc protection system or the SmartCut blades with optimum overlaps. EasyCut R – the professional machine for farmers and contractors
Those who seek faster wilting can opt for a tine or roller conditioner on the rear-mounted units for full-width treatment to the freshly cut material.
M-Rolls have two counter-rotating steel rollers that give uniform conditioning to crops like lucerne, crushing the material effectively and ensuring a consistent wilting process without losses.
The enclosed and fully welded cutterbar meets the highest quality standards and operates dependably and leak-free over many years of hard work. Massive and oil-immersed spur gears impress by very quiet and reliable running in sustained peak-load operation.
Using welding robots and CNC technology, KRONE manufactures its cutterbars to the highest quality standards, ensuring they are fully welded and permanently lubricated. After all, the cutterbar is the heart of every disc mower.
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.
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 models.
There is no load on the roll pins during operation. The bearing is tensioned by a nut and two clamping screws. As a result, the roll pins do not suffer from material fatigue and even after many hours of operation they will break only at their inbuilt load level.
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.
The wedge-shaped cutterbar offers great flexibility to adjust through a large range of settings and leave a short stubble in meadows and pastures as well as long stubble in long-stemmed field crops. An EasyCut mower delivers a reliable performance and clean cut.
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 (SmartCut). In addition, the blades turning to the rear are set further apart to encourage a smooth flow of large volumes of crop.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.

With discs spinning in the B sense of rotation, EasyCut spreads the material across the full cutting width. All discs turn in pairs, spreading the material across the working width for faster and more uniform wilting.
A clean cut is fundamental for clean forage. Clean cuts are attributed to the special design of the cutterbar and the special suspension. The special KRONE DuoGrip suspension system suspends the disc mower in its centre of gravity and provides lateral guidance at the same time. Maintaining a consistent ground pressure across the full work width, the design leads to cleanest cuts on the one hand and light pulling and optimum lateral control on the other.
The parallelogram linkage absorbs lateral forces and guides the unit in direction of travel. At the same time, it helps reduce the load on the jib and the suspension system in the machine’s centre of gravity. The two rods also indicate to the operator whether the tractor linkage is at good height.
The hydraulic and the mechanical suspension springs are extremely responsive and provide perfect cuts even in undulating terrain and at high forward speeds. This is the first step in making clean and high-quality forage and a requirement for a fast and uniform re-growth. The kinematics between the coil spring and the main beam maintain a nearly consistent ground pressure, even in undulating terrain.
Adjusting the spring manually is a fast and easy job. Simply refit a pin to select the target tension. The ground pressure drops as the spring tension increases.
The spring can also be adjusted hydraulically as an option for instant ground pressure changes on the move. The spring tension is released from the seat before the machine is removed from the tractor.
The standard impact damage protection system on EasyCut R models gives you peace of mind as you work along borders, fences and hedges and suddenly collide with an obstacle. When the system trips, the mower swings 1.20 m to the rear and up to 40 cm upwards and clear out of any obstacle. After the obstacle has been passed, the mower swings automatically back into work position.
Implementing a large work width on a mower poses a special challenge to the designers who have to reconcile demands for high work rates with those for good transport and contouring qualities. The solutions are reflected by the KRONE Z-form, the low pivot point, the over-centre transport position and the headland position that does not require operating the tractor’s link arms. KRONE disc mowers offer safe travel and best cuts even in difficult conditions.
The unit folds hydraulically beyond TDC, the single-acting ram on the EasyCut R 280 and R 320 has an accumulator and folds 110° over top dead centre, the double-acting ram on EasyCut R 280 CV, R 320 CV and R 360 folds 124° for better road stability and visibility. Actively folding and unfolding, both versions make for trouble-free changeovers.
Z-shaped arms enable large vertical travel (29° up, 20° down) – ideal for mowing banks and verges.
The Z-shaped arm has a low pivot point for a reduced transport height and yet offers a large ground clearance for smooth travel on rutted field roads.
Shifting the machine weight to the middle distributes its weight more evenly on to the lower links, which improves the tractor ride and gives operators a clear view behind in the mirrors.
The KRONE CV rotor with V-shaped and grippy steel tines spreads the crop at the full working width. Its massive 64 cm (2’1″) diameter and the helical arrangement of the tines warrant a continuous crop flow, high throughputs and superior conditioning.
The tine conditioners on each mower span across the work width from the left to the right top hat, providing a uniform and consistent crop flow across the full width and giving optimum conditioning.
The v-tines are made from hardened steel and mount at a steep angle, treating the forage intensively and powerfully. The tines pivot to the rear when hitting a foreign object whereas forward pivoting is restricted to increase the service life of the pins.
This lever in the multi-step gate varies the gap between the tines and the baffle plate. As you reduce the gap you increase the intensity of conditioning.
Select 900 rpm for intensive treatment and 600 rpm for less intensive conditioning. Setting the speed is easy from the gearshift lever.
Two suspension springs transfer the weight of the mower to the headstock reducing the ground pressure and protecting the sward. As an option, the coil springs can be operated hydraulically from the cab for enhanced operator comfort.
Stands are available as an option to store the machine either in work or transport position – and save space in the machine shed during winter storage.
The folding side and front guards are lined by rubber strips that protect them from damage when colliding with obstacles.
