Problems solved by technology

The tractor driver must therefore maneuver against the edge of the furrow, which requires increased driver attention and additional fuel consumption
The lateral pulling effect of a semi-mounted plow increases as the number of plow bodies and thus the length and lateral projections increases

Embodiment Construction

[0020] figure 1A combination consisting of a tractor 7 and a semi-mounted plow 1 attached to said tractor is shown. The semi-mounted plow 1 is supported on the ground surface in its rear area by a hydraulic height adjustable chassis 4 and in its front area by the same hydraulic height adjustable pulling device 6 of a tractor 7 . The pulling device 6 is designed as a three-point hydraulic system consisting of two lower links 17, 17' and an upper link 16. The lower links 17, 17' can be raised and lowered vertically, however, they are fastened in a laterally fixed manner by means of stabilizer bars and hinge points on the body of the tractor 7. The trailer hitch 5 of the semi-mounted plow 1 has a rail shaft 19 in the lower region, which extends transversely to the center plane 26 of the tractor 7 or the trailer hitch 5 , and the trailer hitch 5 has a spherical The rear end of the lower link 17, 17' is connected with a joint or detent hook or other suitable coupling means. The ...

Abstract

The invention relates to a semi-mounted plough (1) having a rear chassis, said plough trailing behind a plough-towing tractor in a laterally pivotable or steerable manner by means of a vertically oriented joint. In order to compensate lateral pulling for the tractor, which is generated by the traction force of the plough about the vertical axis of the tractor, an energy accumulator (10) is arranged, which generates a torque counteracting the lateral pulling.

Description

technical field [0001] The invention relates to a semi-mounted plow according to the preamble of patent claim 1 . Background technique [0002] In contrast to semi-mounted plows, mounted plows are supported and guided by the tractor's three-point hydraulic system. The laterally pivotable lower link of the tractor's pull-hung plow forms a four-bar linkage obliquely converging in the direction of forward travel, the momentary pole of which is forward of the rear axle of the tractor and forms the virtual traction point of the lower link. Recommendations on the size of the convergence are mentioned in the standard ISO 730. The forces acting during plowing on the individual plow bodies arranged obliquely to the rear can be combined in a common force application point which is located approximately in the center of the plow frame in the longitudinal direction. In the case of a larger suspended plow from four plow bodies in the direction of the plowed ground, the resulting tracti...
