The Krone Big Pack 1290 HDP II now boasts two new features which were previously only available on the Generation 5 BiG Pack. They are the Krone V-knotter and PowerClean.
Hydraulics power the PowerClean system in the BiG Pack 1290 HDP II. The oil flow is supplied by the tractor’s hydraulic circuit and load sensing system. Not only does PowerClean dust the knotter bank but it also keeps other areas of the machine free from debris. This is done by hydraulic turbines in the knotter bay that generate an overpressure which in turn prevents debris from depositing in the first place. The huge advantage of the unique system is that it produces a clean knotter bank that is considerably less prone to wear.
The new V-knotter system on the BiG Pack 1290 HDP II prevents there being twine offcuts. The V-Knotter, which is an inhouse development, produces no scrap tail ends. In contrast to the Cormick single knotter, it produces a knot with the absence of offcuts. However, it offers the enormous reliability of the Deering double knotter.
Double knotters are indispensable on today’s high-density balers. The BiG Pack 1290 HDP II has an extremely high throughput of up to 85 tonnes per hour, resulting in an increased the pressure inside the bale. However, to manage this, the BiG Pack 1290 HDP II uses a patented system of eight double knotters. Effective binding knots which can tie up bales reliably, even in extreme conditions, are formed using this system. Most importantly, this system avoids producing scrap tail ends.
The Krone V-knotter is advantageous in that it produces a finishing Deering knot with longer tail ends that translate into stronger knots. The starter knot on the following bale is a Cormick loop knot. This knot is reinforced with the loop ends tied into a bow shape. The double knotter eliminates any unwanted offcuts and keeps fields and the knotter bank clean.
