Higher throughput, higher comfort, higher work rates
Krone presents the new Big Pack ‘HighSpeed’

Spelle, 21 September 2011. The new Krone Big Pack HighSpeed range of big balers delivers up to 20 percent more throughput, an increase that has been made feasible by two major modifications. One involves the throughput capacity of the VFS packer system, which has been increased by 18 percent. At the same time, the stroke frequency of the piston plunger on the Big Pack 1270, 1290 and 1290 HDP models has also been increased by 18 percent from 38 to 45 strokes per minute. Operators can reduce pto speed from 1,000rpm (45 strokes/min) to 800rpm (36 strokes) when less tractor power is required in light crops, an option that helps cut your fuel costs.

The second modification involves the Variable Feed System (VFS) and its throughput rates. The system comprises four packers and one feeder and operates 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 materi-al, 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, a sys-tem that ensures that the machine produces uniform densities even when dealing with small and narrow swaths.
Further upgrades involve stronger packer and feeder arms and a larger diameter knotter shaft (now increased in size by 15mm to 55mm) to brace the system for higher stresses.
The rear end of the machine has also been beefed up and you can now hitch a bale collector. As a novelty on the Big Pack 1290 HDP HighSpeed, wear parts are bolted to the floor of the baling cham-ber to reduce the costs of wear in this area.

Another practical feature is a system that monitors the upper thread and the knotters. This supplements the existing lower thread control.  The feature is conveniently activated from the Comfort control unit.

The twine boxes have gas struts that allow operators to swing them up and fix them in their opened position for easy service and maintenance. A seal lines the entire outlet to keep dust and debris effectively out and away from the twine. Further practical details are the standard LED lights, which are activated as the panels open and which illuminate the area where the twine is threaded into the system. Three LED work lights can be activated from the cab as an option.

CCI-ISOBUS – an integral system that counts, measures, weighs and tags
Krone offers a number of useful options for the Big Pack High-Speed. For example, you can fit the machine with two ISOBUS moisture sensors that measure the moisture levels at each side of the bale chamber. The system then computes the average level and sends the data to the tractor terminal. Another option is the ISOBUS bale weighing system, which comprises four weighing cells that are integrated in the bale chute. Field tests have shown that the system works to an accuracy of ± 2 percent.
The new ISOBUS Bale Tagger is another innovative tool that helps operators document their jobs. At the end of a baling cycle, this system allows you to program a label using radio-frequency iden-tification technology and write the information to a chip, including bale weight, material moisture, GPS position, time/date, client name, field data and a bale ID code. This way, operators can log any type of bale information and every single bale can be traced back to its origin.

60km/h machine
All Big Pack-HighSpeed versions are also available with 60km/h axles. Naturally, the baler is ISOBUS and LoadSensing compati-ble. This is a professional square baler that ticks every box for professional users.
