Flexible crop cutting for Krone’s BiG Pack balers is now available following the introduction of the company’s VariCut (VC) cutting system to its range of large square balers.
Originally developed for the BiG Pack 1270 and BiG Pack 1290 HDP, the VariCut (VC) features 51 knives mounted in a cassette and can be used in standard combinations of 51/26/25/12/5 or 0, with 51 knives producing a nominal chop length of 22mm.
The VC cutting system produces short chopped straw in the field which is easy to handle and use by either spreading or incorporating into feed, and negates the need for an additional chopping process which can be costly and time consuming.
“The use of short straw has gained popularity in a number of applications ranging from bedding in poultry houses, cow cubicles and pig pens, to adding structure to feed rations to increase ruminant activity and increase digestion,” says Krone marketing manager James Duggleby.
Non-standard knife combinations can be customised by re-arranging the cams on the shaft. Feeding the crop through the knives is a rotor cutter, which now features a forth row of tines to maintain a smooth flow of crop into the VFS pre-chamber and achieve higher throughputs. Any knife combination can be easily engaged by the turning of a cam shaft.
An integral air cleaning system helps minimise the build-up of material around the knives, including the protection springs. The ability of the blade cassette and floor to lower means that any blockages can be removed quickly with minimum effort. The cassettes can also be removed in a matter of moments for easy cleaning and maintenance.
