Out on the demo plots, SimTech had an interesting looking cover crop roller on the front of the tractor running its 3.0m Aitchison drill. Built by Bavarian firm K Wallner, it has a bladed roller running ahead of two rows of wavy discs and a second bladed roller at the rear.
By cutting both laterally and in line with the machine, no plant stems can escape. The amount of work the various different elements do is altered by a pair of hydraulic rams which transfer less or more pressure onto the front and rear rollers.
Additional ballast weights keep it firmly planted on the deck. At the moment it’s under evaluation and there aren’t any firm prices but judging by the look of how it’s put together it won’t be the cheapest option.
