BiG Pack 4x4 Gen. 4

With the Variable Filling System (VFS), high bale density can be achieved at low speeds. The material is precompressed in the pre-chamber before being further compressed in the chamber press, resulting in sturdy and heavy bales. The higher bale density reduces the number of bales, thereby reducing transportation and storage costs, as well as decreasing twine consumption. It is not only more cost-effective but also more environmentally friendly.

With a high-capacity pickup that operates swiftly and efficiently, you can quickly gather more forage and boost your productivity. In case of any blockages, the machine automatically stops for safety reasons and to minimize the risk of damage.

This machine is designed to minimize maintenance and cleaning efforts, saving both time and money. Despite its powerful performance, it consumes relatively little fuel per ton of pressed straw and the twine boxes offers plenty of storage for the long working days. This means you get a cost-effective solution that is not only powerful but also economically beneficial for your business.

A machine that is easy to maintain will last longer, but even better is when there are features that reduce maintenance. The EasyFlow pickup, without cam guidance and with fewer moving parts, reduces wear and the need for maintenance. The twine storage also includes rubber seals as standard to effectively keep dust and dirt away from the storage areas. Additionally, all BiG Pack large balers have adjustable machine sides for easy access, a central lubrication system, drive components with overload clutches instead of shear bolts, and a cleaning system for the knotter units with either compressed air or hydraulically driven fans.

With the Active pickup, you achieve maximum crop flow with five reliable and efficient rows of tines spaced at 55 mm intervals. The camless design is known for effectively clearing the field even under challenging conditions. With an impressive working width, it allows you to work at a high pace, resulting in a high hourly production rate. The Active pickup smoothly adapts to the field's contours with its pivoting support wheels and has a twine roller mounted on top that compresses large, tall swathes for efficient collection. The height is easily and quickly adjusted for different crops and conditions, and the two flexible wheels smoothly follow curves to ensure nothing is missed.

For smoother handling and storage of bales, it is crucial that each bale is of the same size and shape. That's why all BiG Packs are equipped with technology that ensures a constant shape of the bales with each pressing. An electronic control for bale length is centrally mounted in the bottom of the bale chamber, and the operator can easily select the density from 0% to 100% via the control unit. Then, an intelligent pressure control system automatically adjusts the pressure in the bale chamber using two sensors that measure the force from the plunger. The bale chamber's design also ensures that each bale has smooth and neat edges.

VFS (Variable Filling System) from KRONE helps create robust and heavy bales, even when working with small swaths and low working speeds. The material is fed into the feed channel of the pre-chamber where it is pre-compressed. Once the preset pressure is reached, it is lifted into the bale channel, forming a bale flake. In the chamber press, the bale fractions are compressed together by the piston., which strikes at 45 strokes per minute and gains extra power from the large flywheel. The PTO speed can be reduced to 800 revolutions per minute to make the piston strike 36 times per minute, creating robust bales even at lower speeds or with less material, while saving fuel. With an automatic overload clutch, the system ensures consistent maximum performance and evenly compressed bales.

On Krone large balers, all power is transmitted through strong drive shafts, gearboxes, and overload protection, with no chains or shear bolts, which increases reliability. For the BiG Pack with XCut, a separate 4-groove poly V-belt is used to drive the pickup and cutting unit. It automatically shuts off in case of blockages to prevent damage and only starts when the press is in operation. It is also protected by a slip clutch at startup and activates an automatic shutdown clutch in case of overload for extra safety.

The knotter system are available in three different versions: single knotter, double knotter, and V-knotter, which produce sturdy and well-formed bales. They are equipped with an air cleaning system that uses compressed air to regularly clean and thereby ensure that the knotting mechanisms remain clean and can withstand even the toughest conditions.

Producing high-density bales at high speeds with stable knots is a challenge. Krone and Rasspe have therefore developed a patented knotting system for BiG Pack 4x4 with six compact V-double knotters that handle twine with minimal tension. The result is perfect knots even in high-density materials and high driving speeds, while leaving no twine residues in the field. Since BiG Pack 4x4 is a very powerful machine for producing high-density bales, it is recommended to use it in combination with Krone's HDP twine, which is extra strong and specially designed for this baler.
