Abstract

1278987 Earth working machine WARTSILA AB OY 14 Nov 1969 [15 Nov 1968] 55792/69 Heading A1B An earth-working machine comprises motor driven rotating shafts 171, 172 which rotate at a higher speed than other rotating shafts 141, 142, 151, 152, 161, 162, whose motion is caused by ground contact. All of the said shafts are provided with spade- or knife-like pins 28 forming earth-working members. The hydraulic motors 29, 30 which drive shafts 171, 172, are fed with fluid from a pump 31 which is connected to a tractor PTO 43, the fluid travelling to the motors through a main conduit 32 and branch conduits 33, 34, and returning through conduits 37, 38 and 39 to a container 36. An overflow valve 42 is activated if shafts 171, 172 suddenly stop, e.g. on engaging an obstacle.
