BiG Pack 1290 HDP II Gen. 4

The higher density contributes to a more climate-efficient production as there are fewer bales to collect in the field, more efficient road transport, and less storage space. With up to 30% higher pickup speed and increased field velocity, throughput can be boosted by up to 70%. As the material enters the bale chamber through the variable filling system, it's compacted into tight fractions within the bale. This technology enables a 25% higher bale density, and when combined with the V-twine knotter's 8 strings, the bale maintains its stable shape without necessarily increasing twine costs.

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.

Harvesting a crop that yields 4 tons of straw per hectare and producing 500 kg bales instead of 400 kg from a conventional large baler reduces the number of bales to be collected by two bales per hectare. Even though the machine uses higher-quality twine – KRONE recommends KRONE excellent HDP Strong² – twine costs decrease by up to 25% thanks to the higher bale density. The new and self-developed knotter combines the best of two worlds: reliable functionality from the double knotter, and no small pieces of twine residue are left in the field.

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.

Do you have large volumes to bale and want to streamline the transportation of the bales? With the BiG Pack HDP II, you can now achieve even higher density in the bales, allowing you to produce bales with greater weight in a smaller size. On Fyn, Denmark, the company Halm 80 used to produce between 50,000 and 55,000 large square bales each year with 14 balers. Today, they have 6 BiG Pack balers from Krone instead and still bale the same amount, but with higher density, which has had a positive impact on profitability.

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 large flywheel, weighing approximately 610 kg, absorbs loads and keeps the machine running smoothly with less power usage. The hydraulic motor accelerates the flywheel before engaging the tractor's PTO, and the intermediate gearbox reduces wear on the drive shaft while increasing PTO speed for maximum flywheel performance. All BiG Pack HDP II models feature a hydraulic start-assist system to ensure a smooth machine start.
