Towing coupling for agricultural vehicle - has coupling retaining member infinitely adjustable on vertical guide by power actuator

摘要

The securing arrangement for a towing coupling to an agricultural vehicle has a coupling claw fixed to a retaining member (5) which is vertically adjustable on a guide (1) fixed to the vehicle. The member is infinitely adjustable along the guide by a power actuator (9, 10). The guide may comprise two parallel rails (1a, b) whilst a power actuator is provided for each rail. The rails may form U-section enclosures for vertical portions (5a, b) of the member. The actuators are pref. synchronised, and may be single-acting power cylinders returning under gravity.
