Harvester Sharpening System Needs No Adjustment
 |
“The new stone sharpening process is standard on all our current Big X harvesters and will be available as a retrofit kit for 80 series harvesters,” says Jillian Helgeson, Krone North America.
Features of the new sharpening system include a telescoping thread that automatically adjusts the position of the grinding stone. It offers up to 2,200 grinding cycles without a manual reset of the stone. By comparison, traditional systems require servicing after 400 to 450 grinding cycles.
An innovative clamping system makes the entire stone available for grinding. By comparison, only 40 to 55 percent of the stone surface is available for sharpening with traditional clamping systems.
Replacing the stone is easier, too. Undo two screws, remove the down-holding deck from the stone, and then remove the stone from its carriage. The patented assembly also protects the stone from contamination.
The new system’s guide shaft is lighter weight and smaller in diameter. Propped in four positions at 267-mm (10 1/2-in.) intervals versus 1,160-mm (45 1/2-in.) intervals, it has increased stability and reduced vibration. This cuts the risk of deformation and bouncing. Improved positioning of the grinding faces and the shear bar on the chopping drum, as well as blade positioning, improves the quality of the chop.
The combined features save operator time and reduce service and maintenance for reduced costs. They optimize chopping quality and ensure more consistent sharpening of all components.
