摘要

A machine for forming large cylindrical bales of hay has a baling chamber consisting of a frusto-conical crop receiving portion (18) and a cylindrical crop discharge portion (22). The portions are arranged end-to- end and are defined by rolls which are driven to roll the crop round on itself into the form of a bale. The bale is compacted in the discharge portion by being forced by incoming crop against an abutment plate (52) which is hydraulically controlled. The bale is wrapped with twine from a tying device and severed by a cutter before being released through a gate (30). The whole operation is continuous. In order to produce bales with a desirable density without undue stress to the machine, a control system (58) relieves the hydraulic pressure affording the resistance to bale movement by the abutment plate (52), Sensors (60, 62) detect any drive torque of the machine outside a predetermined range and any lack of advancement of the bale, and their outputs are fed to a computer (64) controlling a relief valve (66) enabling the abutment plate (52) to yield and the growing bale to advance further.
