Quick-change blades are a must for many farmers and contractors, because this way they can replace blades quickly and easily on the site.

With some cutting 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 swaths. For a stripeless swath, we have therefore increased blade overlaps on the cutter blades turning outwards between the discs turning away from each other. In addition, the blades turning to the rear are set further apart to encourage a smooth flow of large volumes of crop.

If the system is suddenly overloaded, the impact is not directed to the spur wheels in the cutterbar, instead the roll pins in the sprocket drive shaft shear off. The pinion shaft, which continues rotating, turns the cutting disc upwards via a lifting thread. moving it out of the risk zone and the orbit of the neighbouring discs. As a result, SafeCut prevents damage to the spur wheels and the neighbouring discs. The roll pins are replaced within a few minutes, saving costs and minimizing downtime.

You know it too well – foreign objects can cause great damage and costly repairs. ­KRONE SafeCut offers a maximum of protection and peace of mind. A unique technology protects the cutting discs from foreign objects. The XDisc comes with SafeCut as standard.

KRONE XDisc is the versatile specialist mower for whole crop silage that cuts the crop cleanly and without wastage. The huge 900 mm diameter auger makes the unit enormously powerful and has no trouble picking up very long and bulky material.

With its working width of 6.20 metres, the ­KRONE XDisc 620 direct cut header achieves a high acreage output and therefore efficient harvesting of whole crop silage.

The XDisc 710 can be optionally equipped with side cutting blades which can be easily and conveniently swivelled up and down independently of each other hydraulically from the cabin of the forage harvester. This innovative and unique function offers an enormous advantage: efficient utilisation of the maximum working width prevents harvest losses from laterally protruding ears or climbing plant parts at the edge of the crop; this would occur if the cutting blade was not actively swivelled upwards.

To ensure a continuous crop flow even in dense and tall crops, the XDisc 710 can be optionally equipped with a crop press roller unit. This ensures an even crop flow to prevent blockages and enables smooth operation even under extreme conditions.

As there is no need to find a parking space for the transport wagon, there is also no need for awkward manoeuvring before harvesting begins. The XDisc 710 is easy to handle thanks to a swivelling single axle on the right next to the header adaptation and a folding drawbar with support jack on the left front side. By hydraulically swivelling the drawbar and axle, both chassis parts disappear behind the header during field work, leaving the working area clear

For transport on public roads, the chassis is swivelled under and the drawbar hydraulically next to the direct cut header. After the folding process, the direct cut header is attached to the tow coupling of the forage harvester. The integrated transport chassis replaces the additional transport wagon which was previously required, thereby making field changes considerably easier. Thanks to its innovative design, the direct cut header can be transported on the road safely and in compliance with the law as a stand-alone unit with an integrated lighting unit.

The drive chain for the auger conveyor is actively lubricated – this helps to minimise maintenance work on the direct cut header and to increase the service life of the drive chain

For a consistently clean cut in all conditions, the bearing pressure can be infinitely adjusted from the cabin of the forage harvester. The cutting height can be adjusted very easily and without tools using the centrally adjustable ground skids. If it is necessary to adjust the cutting angle, this is possible via a 3-way adjustable hole pattern on the round arch holding fixture.

The KRONE XDisc 710 impresses not only with its performance, but also with its outstanding accessibility and ease of maintenance. To change the blades, the guard cloth is folded up and the blades are replaced using the quick release fastener. The blades can be removed quickly and easily using the standard spare blade drawer. In addition, the centre hood can be easily swivelled upwards to allow free access to the intake rollers.

The large 900 mm diameter feed auger is designed for high throughputs. Its speed can be adjusted in three stages to the intake speed of the forage harvester, depending on the cutting length of the mown crop. In addition, the base height of the auger conveyor can be manually adjusted in three stages using eccentrics to allow the crops to pass through in the appropriate way. In addition, the free-moving auger conveyor can simply deflect upwards in the case of bulky crops.

The powerful XDisc 710 is characterised by its exceptional robustness, enormous efficiency and high throughput. Two rigidly connected cutterbars are driven in a force-fit manner via universal shafts and angular gearboxes, starting from a central input gearbox. This guarantees an even cut even at maximum throughput, essential for outstanding chop quality. The drive train is specially designed for high input power and does not require an overload clutch. The auger conveyor is protected by a star ratchet clutch integrated into the gearbox and is driven by an actively lubricated chain drive, thereby ensuring a long service life

With its impressive working width of 7.10 m, the KRONE XDisc 710 direct cut header sets new standards in terms of performance. Thanks to its precise cut and perfect crop flow, it offers an extremely efficient solution for harvesting energy crops. With its integrated transport chassis, it also makes it quick and easy to move between locations, further increasing efficiency

The 275-litre dispenser for adding silage additives at high rates (0.5-7.5 l/min) is integrated on the offside platform next to the cab. Two 20-litre silage additive dispenser for small dose rates (0.03-0.25 l/min) can be installed on the left platform. In addition, it is possible to fit an external silage additive system. The silage additive can also be added relative to yields (option).
