Krone looks at reverse drive

Anyone familiar with precision grass harvesting will remember the domination of the drum-type trailed harvesters of the 1980s and ‘90s.

This was overtaken by the popularity of flywheel type machines, which delivered more output, less fuel consumption and a better chance of surviving foreign object ingestion.

Those flywheel-based machines evolved from rear-linkage mounted, reverse drive machines that were the norm when forage maize became popular in northern Europe. This was at a time when self-propelled units were only just starting to appear.

German harvesting specialist Krone is now looking to turn the clock back and creating a sense of déjà vu with its latest development project – a prototype reverse-drive forage harvester that has been undergoing testing in maize.

Designed to be mounted on prime mowers like the Claas Xerion 5000 or the Fendt 1050, the prototype weighs over six tonnes and can be equipped with Krone’s six to 10 row maize, conventional grass pick-up or direct-cut, whole-crop headers.

It features a chopping cylinder from the Big-X harvester range, and hydraulically-driven header and feed rollers.

The prototype is said to be a match for Krone’s Big-X 480 cousin in terms of output and chop quality, with reduced fuel consumption and a significantly lower capital cost.

Case IH Wins EIMA Award for Optum Suspension System

With the biannual Italian EIMA machinery Expo less than a month away, Case IH has taken out a Technical Evolution award for the Advanced Vehicle Suspension system available on its Optum 360–440 series tractors.

The Advanced Vehicle Suspension system, available on Optum 360, 390, and 440 models, responds to changing conditions, automatically adjusting how the suspension reacts to absorbs shocks and controlling vehicle movement.

In operation, sensors monitor the vibrations transmitted from the tractor chassis to the operator cabin, allowing the system to adjust suspension damping in real time. The control system incorporates key priorities, such as comfort at lower speeds and stability as speed increases, while also reacting to factors such as lower tyre pressures, where the tyres absorb more of the initial shock.

Case IH said as suspension requirements change throughout the working day, as tractors move between the paddock and road transport, the system manages suspension response in the background as tasks, speeds and conditions change, leaving the operator without the need to make manual adjustments.

Richard Hollins, Optum series tractors global product manager, said: “Pioneering technology must earn its place in the working day. Farmers and contractors will judge an investment by what it delivers, including manageable ownership costs, dependable up-time and the versatility to tackle different jobs. With AVS, we are putting intelligent control to work for comfort and stability, without giving the operator another setting to manage.”

Organised by FederUnacoma, the Italian Agricultural Machinery Manufacturers Federation, the contest has been part of EIMA since 1986, with the Technical Evolution distinction awarded to products that introduce original improvements to solutions already manufactured or patented.
