Dutch effluent specialist Vredo is testing 15 and 18-metre wide slurry injection rigs for the upcoming 2022 spreading season.
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.
