Multiple section reversible plough

Pressure control circuit for a combination of a reversible plough with a

A reversible plough, that in one embodiment is of the semi-mounted type, and comprises a main beam, a coupling structure at the forward end of the main beam, and a carrying beam. Pairs of plough bodies are mounted along the length of the carrying beam. The carrying beam is pivotably connected to the main beam to move between a first and a second ploughing position for plough body reversal. The reversible plough further includes a coupling beam that is secured to the carrying beam, and a soil preparation device such as a packer that prepares the soil turned over by the plough bodies for seed. The coupling beam projects laterally from the coupling beam in either ploughing position and is moveable with the carrying beam during plough body reversal. A hopper is mounted at a fixed location relative to the packer and the reversible plough combination, and a distributor is mounted on the packer and arranged to distribute the hopper content onto the ground. The hopper contents are conveyed by a flexible distribution system that includes a line extending between the hopper and the distributor.

A hole opener used in conjunction with drilling in at least one of boulder and rubble stone formations includes first and second sets of cutters. Each of the cutters of the first and second sets of cutters has cutter teeth thereon and further include a shaft. The hole opener also includes a tubular carrier body, a first device for fixing the first set of cutters to the tubular carrier body so that the first set of cutters is positioned in a common first lateral plane with respect to a longitudinal axis of the tubular carrier body, and second device for fixing the second set of cutters to the tubular carrier body so that the second set of cutters is located in a second lateral plane with respect to the longitudinal axis of the tubular carrier body and at an axial distance from the first set of cutters along the longitudinal axis. The first device combined with each of the cutters of the first set of cutters extends a first radial distance from the longitudinal axis, the second device combined with each of the cutters of the second set of cutters extends a second radial distance from the longitudinal axis, and the first radial distance is less than the second radial distance. Each of the shafts of the cutters of the first and second sets of cutters are rotatably and releasably connected to a corresponding one of the first and second devices.

An assembly on an agricultural implement, especially a semi-plow, wherein the assembly comprises a plurality of pivotable and mutually interacting parallelograms and a plurality of partially interconnected link members (12, 26, 31, 34, 41) which regulate the implement's support wheel (22) and a turn limiter (44), whereby the turn limiter (44) is automatically regulated when the implement is being adjusted to adapt it to the tractor track as well as to the desired plow strip width so that the maximum angle of deflection, to the right or to the left, between the tractor and the turn limiter (44) is held constant no matter what the angle assumed by the implement in relation to the driving direction, said turn limiter thus preventing the tractor from abutting against the implement when the tractor turns sharply, while at the same time the wheel (22) is automatically correctly adjusted when the implement is being adjusted to adapt it to the tractor track and the desired plow strip width, whether the implement is driving in a straight line or on a curved path.
