Agricultural machine
First Claim
1. An agricultural machine comprising an implement which includes coupling means for coupling said implement to a front lifting hitch of a tractor, said implement, for the purpose of being supported on the ground, comprising a roller connected with a frame, pivotal supporting means between the frame and the roller for providing a mutual pivoting movement about an axis oriented in the direction of the machine'"'"'s normal direction of travel.

Abstract
Disclosed is a cultivator mounted to roll about a horizontal axis transverse to the direction of travel of the machine in combination with a hopper. The cultivator and hopper are mounted on a frame which is adapted to be connected to a three-point hitch of a tractor. The cultivator is connected to the frame under and behind the hopper and by a pivotal shaft which interconnects bearings confined fore and aft by U-profiles. The cutivator is thus tiltable within limits relative to the frame and hopper and is also turnable within limits so that the cultivator turns with the tractor. It also provides support for the hopper. A centrifugal air pump is mounted on the hopper which, via a pair of venturi-type devices, draw in granular material, such as seed, from the hopper for distributing same on the soil, the hopper having a pair of metering devices which meter granular material received by the venturi-devices. The venturi-type devices are mounted at the bottom of the metering devices to be hingeably or slidably removable so that granular material can be collected in buckets or the like directly from the metering devices to ascertain the rate that granular material is being dispensed by the metering devices.

- 1. An agricultural machine comprising an implement which includes coupling means for coupling said implement to a front lifting hitch of a tractor, said implement, for the purpose of being supported on the ground, comprising a roller connected with a frame, pivotal supporting means between the frame and the roller for providing a mutual pivoting movement about an axis oriented in the direction of the machine'"'"'s normal direction of travel.
- 27. An agricultural machine which comprises a three-point hitch for connection to a tractor, a hopper supported by said three-point hitch, a ground engaging roller for treating the underlying soil connected to said three-point hitch between said three-point hitch and said hopper, the connection of said roller to said three-point hitch comprising a leg which is constructed and arranged so that said roller is rotatably coupled thereto at a lower aspect of said leg, a bearing support extending generally forwardly and horizontally mounted on an upper aspect of said leg so that said roller is tiltable within limits relative to said bearing support, at least one bearing joined with said bearing support, a U-shaped section receiving said bearing so that said bearing is disposed in said U-shaped section so as to be movable within limits generally horizontally and transversely relative to the normal forward direction of travel of the agricultural machine, said U-shaped section providing at least in part support for said hopper via said bearing and said roller.
- 31. An agricultural machine which comprises a three-point hitch for connection to a tractor, a ground engaging roller for treating the underlying soil connected to said three point hitch, the connection of said roller to said three-point hitch comprising a leg which is constructed and arranged so that said roller is rotatably coupled thereto at a lower aspect of said leg, a bearing support extending generally forwardly and horizontally mounted at an upper aspect of said leg so that said roller is tiltable within limits relative to said bearing support, at least one bearing joined with said bearing support, slide means receiving said bearing so that said bearing is slidably retained on said slide means to move generally horizontally and transversely relative to a normal of travel of the agricultural machine.
- 35. An agricultural machine comprising an implement for coupling to a front lifting hitch of a tractor, said implement comprising a roller connected with a frame, pivotal supporting means between the frame and the roller for providing a mutual pivoting movement about an axis oriented in the direction of the machine'"'"'s normal direction of travel, a connection being provided between said frame and said roller, said connection comprising a quadrangle hinge construction having substantially upwardly directed pivotal axes.
-
42. An agricultural machine comprising an implement for coupling to a front lifting hitch of a tractor, said implement, for the purpose of being supported on the ground, comprising a roller connected with a frame, pivotal supporting means between the frame and the roller for providing a mutual pivoting movement about an axis oriented in the direction of the machine'"'"'s normal direction of travel, a substantially triangular coupling trestle for said coupling to a front hitch of a tractor, lower and upper arms mounted on said trestle, said lower and upper arms extending substantially horizontally in a forward direction relative to the machine'"'"'s normal direction of travel, said lower and upper arms forming a connection of said coupling trestle with a forward framework comprising two transverse horizontal carriers interconnected by struts.
-
43. An agricultural machine comprising an implement for coupling to a front lifting hitch of a tractor, said implement, for the purpose of being supported on the ground, comprising a roller connected with a frame, pivotal supporting means between the frame and the roller for providing a mutual pivoting movement about an axis oriented in the direction of the machine'"'"'s normal direction of travel, said roller comprising an axle and said pivotal supporting means comprising a transverse horizontal roller frame beam and arm portions extending from said frame beam, said arm portions connected with said axle of said roller, a support member on said frame beam and a pivot mechanism mounted on said support member disposed between said frame and said roller.
-
44. A agricultural machine comprising an implement for coupling to a front lifting hitch of a tractor, said implement, for the purpose of being supported on the ground, comprising a roller connected with a frame, pivotal supporting means between the frame and the roller for providing a mutual pivoting movement about an axis which is oriented in the direction of the machine'"'"'s normal direction of travel, said roller comprising a central axle, roller segments mounted on said central axle, said pivotal supporting means which is provided between said frame and said roller comprising at least one arm portion extending between two of said roller segments towards said axle.
- 45. An agricultural machine comprising an implement for coupling to a front lifting hitch of a tractor, said implement, for the purpose of being supported on the ground, comprising a roller connected with a frame, pivotal supporting means between the frame and the roller for providing a mutual pivoting movement about an axis which is at least oriented in the direction of the machine'"'"'s normal direction of travel, said pivotal supporting means comprising a pivot mechanism which comprises a U-shaped section, a bearing received in said U-shaped section, said bearing and said U-shaped section constructed and arranged so that said bearing travels, within limits within said U-shaped section, in a curved path, a quadrangle hinge construction defining said curved path, the movement of said bearing in said curved path being caused by mutual pivoting between said frame and said roller.
- 47.
