Krone Big X

Purpose and Class of Machinery

The Krone Big X forage harvester series represents the flagship of high-performance equipment designed for silage harvesting. This class of machinery is targeted at large agricultural enterprises and professional contracting firms handling vast areas of corn, grass, and other forage crops. The Big X series features a unique engine placement concept that ensures optimal weight distribution and a direct drivetrain to the working components, which minimizes power losses during torque transmission.

Engine and Transmission

The model range is equipped with powerful Liebherr and MAN engines, delivering between 600 and over 1100 horsepower depending on the modification (e.g., 780, 880, 1180). Utilizing large-displacement engines allows for high torque at low RPM, which is critical when operating in demanding field conditions. The infinitely variable transmission ensures precise adherence to the set harvesting speed, adapting automatically to crop density and field terrain.

Driveline and Chopping System

A key advantage of the Krone Big X is the innovative MaxFlow chopping drum. It features knives arranged in a chevron pattern, ensuring a uniform flow of biomass and a consistent chop length. Thanks to the VariQuick system, the operator can quickly switch between using the chopping drum and the corn conditioner. The OptiMaxx corn conditioning system features an increased surface area for the rollers, guaranteeing that every kernel is cracked, even at short chop settings.

Hydraulics and Attachment

The harvester’s hydraulic system is engineered for handling heavy-duty adapters, such as the EasyCollect corn headers with widths of up to 14 meters. The lifting mechanisms possess a high safety margin, ensuring stable header guidance over undulating terrain. The automatic cutting height control and ground contour following systems minimize stubble damage and prevent foreign objects from entering the chopping chamber.

Application in Agricultural Operations

The machinery demonstrates peak efficiency in scenarios requiring high throughput per unit of time. The StreamControl system allows the operator to adjust the crop discharge distance from the cab, simplifying trailer loading regardless of the harvester’s position relative to the transport vehicle. Due to its high discharge velocity, the Krone Big X ensures a continuous logistics cycle, eliminating downtime during forage transport to storage sites.

Maintenance and Reliability

Krone engineers have implemented a concept of easy access to vital components: all elements of the chopping system, including the shear bar and the drum, are accessible for inspection and replacement via service hatches. The modular construction facilitates maintenance in field conditions. The Krone SmartConnect system provides remote monitoring of the machine's status, transmitting data on fuel consumption, throughput, and maintenance intervals in real-time, thereby reducing the risk of unexpected breakdowns.

Who Should Use This Equipment

The Krone Big X is the optimal solution for farming operations where timing is critical. The high total cost of ownership is offset by unmatched productivity, capable of reducing the silage harvesting window by 20-30% compared to smaller-class harvesters. It is a choice for those prioritizing feed quality, superior chopping precision, and the long-term durability of their capital investments in machinery.
