Krone packs a punch with new features

The Krone Big Pack 1290 HDP II now boasts several new features that used to only be available on the Generation 5 Big Pack.
Highest density and throughput in the field – now with eight snip-free double knotters and the unique Krone PowerClean knotter cleaning system as standard.

These are, the company says, the well-proven PowerClean knotter fans and eight reliable Krone V-knotters that produce no scrap tail ends.

The Krone PowerClean is a hydraulic cleaning system that dusts not only the knotter bank but also other areas of the machine that are usually contaminated with 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, Krone says. The Big Pack 1290 HDP II powers the PowerClean system hydraulically. The oil flow is supplied by the tractor’s hydraulic circuit and load sensing system.

Knotting on the Big Pack 1290 HDP II now means there are no twine offcuts – thanks to the Krone V-knotter, an in-house development, which produces no scrap tail ends. The V-knotter offers the best of two worlds: the enormous reliability of the established Deering double knotter and the absence of offcuts of the Cormick single knotter.

Double knotters are indispensable on today’s high-density balers. The additional challenge on the Big Pack 1290 HDP II is its extremely high throughput of up to 85 tonnes per hour (t/h), which increases the pressure inside the bale. Due to its high throughput and high bale densities, the Big Pack 1290 HDP II uses a patented system of eight double knotters that produce effective binding knots, which, even in extreme conditions, tie up bales reliably without producing scrap tail ends.

Another advantage of the V-knotter is its modified functions, which produce 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 where the ends are formed into a bow which increases the knot strength. The double knotter eliminates those unwanted offcuts and keeps fields and the knotter bank clean.

The knife is now in a fixed position in front of the twine holding disc, the scraper lever is equipped with an extractor and thus pulls the remaining twine in a loop into the starting knot. The knotter beak is open in a V-shape, allowing the loop knot to be pulled out downwards.
