Each plough beam possesses an abutment-piece for the piston rod of a compression cylinder which moves on a pin in the bracket. A power accumulator in the form of a gas spring is fixed by means of a clamping ring into the cylinder. A cruciform pipe-nipple is connected to its connection. Pipes leading to the cylinder and to power accumulators are screwed with the same nipple. A stopcock with a manometer is joined to tubing leading to the tractor, for pumping oil into the cylinders and power accumulators. A pipe joins all the power accumulators. |
