DEVICE FOR STABILISING THE LOWER STEERING ARMS OF A TRACTOR

摘要

The invention relates to a device for stabilising the two lower steering arms 1 of a tractor. The lower steering arms 1 can be actuated by a hydraulic power lift 9. Each lower steering arm 1 is associated with a side strut 6 which comprises a single-acting hydraulic cylinder 7 for stabilising and securing the lower steering arm 1. By means of a pre-selection valve 12 and a control valve 13, the hydraulic cylinders can either be connected to the power lift 9 via a line or they are loaded separately by a second pressure source P2, so that independently of the actuation of the power lift 9, the two lower steering arms can be centrally centred by the hydraulic cylinders 7.
