MENSCHEN TITLE THEME Optimal chop quality begins with correct rpm alignment between header and intake. crucial that this be precisely reset after every sharpening. Additionally, visual inspection of cutterhead and counterblade area should be conducted through the V-flaps at intake. A couple of handturns here allow the driver a good view of the wear situation and/or result of sharpening.” Product specialist Büter adds that if the silage harvester features the Krone VariLOC system, the driver can rapidly and easily alter chop length. “With a 28-knife drum, chop length can be altered with VariLOC between 4 mm and 30 mm. However, important here is timely alignment of the transmission, preferably at around 17 mm. Then, the machine performance is exactly right,” he explains. AS NEAR AS NECESSARY The corn conditioner delivers intensive processing of the maize grain and plant material. With the Krone BiG X, roller and disc conditioners are available. Through their differing teeth numbers and rpm speeds, roller conditioners have a defined operational range while the disc conditioner has a very wide operational spectrum and can be universally applied from short to long chop. With both systems, the machine operator can, from the cab, match the slit gap in the rollers or discs to one another. “These correctly coordinated alignments are important in determining the quality of work,” underlines Büter. 1 2 Regular visual checks should be carried out in the cutter drum and counterblade area. “Compared to the rollers, the discs react more sensitively to gap alterations because of their larger frictional area. Therefore, according to forage crop condition, the operator has to reach the treatment result wanted through trial, with readjustment where necessary. The rule has to be: As near as necessary and not as close as possible. If the slit spacing is too close, wear increases but not necessarily the quality of the work.” Daniel Büter concludes with a further tip: “The most important of the proverbial fine-tuning screws is, and always will be, the communication between silage harvester driver and farmer. Timely and regular control of silage quality during harvesting is an important key to success.” Forage wagons MORE MODEL TYPES For the new AX forage wagon series, models AX 280 and AX 310 are now available not only with the proven options folding backgate and full steel construction but also with the variant silage pick-up and chopper attachment. For swath collection, Krone insists on proven pick-up technology, with new elements. Pick-up tines form a “W” pattern: the patented design ensures uniform distribution of the harvested material across the total breadth of the cutting rotor creating, says the manufacturer, the basis for a very good chopping quality. The chain and slat floor conveying system within the wagons is lowered by 100 mm towards the front; this shortens conveyance distance and reduces power requirement. Pick-up width is 1,800 mm (DIN 11220); this allows broad swaths to be collected cleanly, even on the curve. The AX forwarding and cutting rotor with EasyCut R 400 25 mm breadth Hardox conveyor system includes the advantages of standard rotor and of oscillating conveyor. 32 knives with gaps of 45 mm ensure best chopping quality (theoretical chop length: 45 mm) with low power requirement. Further plus points: the AX variants HL/HD feature VERSATILE APPLICATION With its EasyCut R 400, Krone presents a new disc mower with working width of 4.04 m. The robust attachment bracket, optimised SmartCut disc beam, individually secured SafeCut mower discs, reliable collision protection, disc beam safety breakaway with springs and the mower’s narrow transport width all make the EC R 400 a reliable, simple and flexible disc mower for versatile application. For transport, the mower is swung rearwards hydraulically and the protection cover au- hydraulically-folding upper front wall for easier filling of the wagon from a front-filling harvester spout and the fully-enclosed bodywork with angled mudguards and hood mean minimum retention of silage material on these surfaces. tomatically folded upwards. This keeps both transport width and height down, a real plus point when accessing gates and barn doors. The EC R 400 comes equipped with rear lighting and rear warning plate as standard. Should the EasyCut R 400 disc beam collide with an obstacle during cutting, the inbuilt hydraulic safety system allows the beam to rapidly swing back while moving upwards at the same time. Damage to the machine is thus avoided. The mower beam is attached to the cantilever arm at point of gravity. The wide lateral swing range allows for good adjustment to ground surfaces. With two adjustable, rapidly reacting, suspension springs, implement downward pressure is applied uniformly over the entire working width and is adjustable to meet different operational conditions. Optionally available is hydraulic pre-tensioning of the spring system. 20 21
