ABSTRACT:
A trailer for loading and transporting cylindrical bales of straw fodder or other materials, of the type having an off-set draw-bar, comprising a chasssis supported by wheels, a main platform integral with this chassis, a fork articulated in the region of the front edge of the main platform and pivotable between a low bale pick-up position, in which the free end of the fork is close to the ground, and a high loading position, in which the free end of the fork is above the plane of the main platform, a control member capable of assuming a first or second state and a drive member controlled by said control member, causing the fork to pivot upwards when the control member is in its second state, and allowing the fork to pivot downwards when the control member is in its first state.
This trailer comprises furthermore a sensing member, of a type known per se, operationally connected to the control member for sensing the presence of a bale on the fork in the low position, and causing consequently the movement of the control member towards its second state.
