BiG Pack 1290 VC Gen. 5

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.

This machine features several smart functions to simplify operation. VariCut is one of BiG Pack's cutting systems that offers up to 51 knives for high-quality short-chopped straw. It is powered by a belt for maximum efficiency and performance and automatically stops in case of overload, with easy restart from the cabin. Its integrated knife protection and easy maintenance make it a convenient choice, with a practical service plate above the knives and a retractable frame for easy handling during maintenance.

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.

VariCut is BiG Pack's cutting system with a variable knife control system distinguished by a maximum of 51 knives for producing high-quality short-chopped straw. The rotor and Pick-Up are belt-driven, offering maximum power and performance. In case of overload, the drive of the Pick-Up and rotor is automatically halted, and the knives are swung out of the material flow. Once the issue is resolved, work can be easily resumed hydraulically from the cabin by restarting the drive of the Pick-Up and rotor. Then, the knives are swung back into the material flow.

The knife cassette in VariCut features a convenient service plate above the knives that can be easily folded up with a handle to remove crop residues and deposits. An integrated air pressure system with nozzles cleans the area around the knives and the individual knife protection system. The knife cassette is mounted on a retractable frame to keep the cassette together and maintain precision during operation, as well as to absorb any vibrations. Additionally, the frame with the knife cassette is easy to handle during maintenance; it can be effortlessly slid out to the side, removed, and transported with a pallet truck.

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 VariCut, 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.
