Krone is launching a range of higher output balers aimed at large-scale farmers and contractors that can boost work rates by an extra 20 per cent, but when working in light crops, can also allow operators to reduce the PTO speed from 1000rpm to 800rpm to save fuel costs.
Higher output on the Big Pack HighSpeed baler has been achieved by increasing the throughput capacity of the Variable Feed System (VFS) by 18 per cent and also the stroke frequency of the piston plunger on the Big Pack 1270, 1290 and 1290 HDP models.
Also included in the new HighSpeed baler range is the highest output machine – the Big Pack 4×4. It includes pick-up design technology taken from the Big X forage harvester that boosts output by up to 80t/hr of straw into 1.20m x 1.30m bales.
The pick-up on the 4×4 is positioned closer to the packer to provide a smoother flow of crop. Also, its roller crop guard is now top hinged to the direct drive feed roller, allowing the pick-up to stay open on either end so it can always pick up the crop thoroughly, even in extremely wide swaths. The new baler includes Isobus and load-sensing compatibility as well as 60km/hr axles and tyres as an optional extra.
Throughput rates of the VFS on all models have also been increased with four packers and one feeder operating in five stages to feed the material into the pre-chamber where it is compressed before it is allowed to enter the baling chamber.
When the pre-chamber is filled up with material, the haydog retaining it in the chamber gives way to the pressure and clears the way into the baling chamber. Then the new cam-controlled active swing is pushed out of the VFS chamber, producing uniform densities even when dealing with small and narrow swaths.

Increasing output goes hand in hand with strengthening the packer and feeder arms as well as increasing the diameter of the knotter shaft by 15-55mm. Beefing up the rear end also includes a hitch for a bale collector.
Practical features include a system that monitors the upper twine and the knotters that supplement the existing lower twine control. The twine boxes have gas struts to allow operators to swing and fix them in their opened position for easy service and maintenance. A seal lines the entire twine box to keep dust and debris effectively out and away from the twine.
Options for the Big Pack HighSpeed baler include Isobus for counting, measuring, weighing and tagging. This way, operators can log any type of bale information and every single bale can be traced back to its origin.
