Ploughing on stony ground with OptiStone overload protection - simply explained [2024]

Stony soils pose particular challenges for plows and tractors. With the OptiStone hydraulic overload protection system, stony fields can be cultivated without damaging the plow. The clever mechanism enables large release ways vertically and laterally at the same time and ensures a constant connection between body and frame. This means there is no risk of losing the body at any time. The release forces can be adjusted via the hydraulic system so that it is always possible to react precisely to the local conditions.
LEMKEN expert Josef explains the advantages and details of the OptiStone overload protection device using a functional model.
The OptiStone overload protection system for trouble-free plowing is available for all reversible mounted ploughs from Juwel 7 to 10 and all semi-mounted ploughs.
