摘要
An agricultural baler (10) comprising a baling chamber (18) and means (20) for loading successive charges of crop material therein also comprises means (94, 87) for automatically adjusting the cross section of the baling chamber (18) to the load experienced by the plunger (24) during compression of these charges and thus controlling the density of the bales formed therein. The density control system further comprises means associated with the actuator means (87, 31) of the baling chamber for precluding adjustment of the cross section when no new charge of crop material has been introduced into the baling chamber (18). These means comprise a sensor (60) sensing the passage of such charge along a wall portion (36) of the baling chamber (18) and a by-pass valve (82) which controls the pressure of hydraulic oil provided to the actuator means (87, 31). Thus is prevented that the cross section of the baling chamber (18) is reduced further when the baler (10) is turned on headlands and no new charges of crop material are inserted into the baler (10).
