Abstract

In an agricultural implement, a pick-up assembly (1) is coupled to the frame (3) of the implement though at least one hydraulic actuator (15). The actuator comprises a cylinder (20), a first piston (23) and a rod (24) attached to the first piston. The cylinder (20) and the rod (24) are pivotably connected to the pick-up assembly (1) and to the frame (3) or vice versa, so that the actuator enables pivoting at least part of the pick-up assembly about a horizontal pivot axis (6), thereby lifting or lowering the assembly relative to a ground level (2). The cylinder (20) comprises an inlet port (27) positioned so that lifting the pick-up is enabled through the supply of hydraulic fluid to the inlet port. According to the invention, a second piston (25) is arranged in the cylinder, between the inlet port (27) and the first cylinder (23), and the rod (24) comprises an internal channel (24) that provides access to an interior space (33) of the cylinder, situated between the two pistons. This configuration enables setting a fixed stop position by supplying a given volume of hydraulic fluid between the pistons (23,25) or between the second piston (25) and the inlet port (27) of the cylinder, and maintaining said volume in the thus created space.
