ABSTRACT:
The invention has been designed to be applied to conventional agricultural tillage equipment. The invention provides a new and improved mechanism for lifting and lowering, controlling and maintaining an accurate level of the equipment. It consists of a single hydraulic cylinder powering a scissor-type mechanical principle designed in such a configuration that the power provided by the hydraulic cylinder is transferred to each pivoting axle. The advantage of the device is that it is a relatively light weight arrangement while retaining stability and rigidity of the arrangement in operation.
