An implement for automatically milking animals, such as cows, comprising a robotic mechanism, two computers each having a display screen and keyboard, the implement having a plurality of exchangeable parts provided with signalling means to transmit information when an exchangeable part is malfunctioning, the signalling means also identifying the malfunctioning part on one of the display screens of a computer. An emergency electrical battery is provided at an individual parlor containing the impl…

A frame beam supports a plurality of plow bodies, the front plow body of which has a one-piece moldboard and is pivotable about an upwardly extending axis. Part of the moldboards of each of the following plow bodies is pivotable about an upwardly extending axis relative to the remainder of each such moldboard. Adjustment is made through rod systems from a common rod which is displaceable mechanically by a screwthreaded spindle or hydraulically by a piston and cylinder assembly. The latter adjust…

A compact electronic calculator comprising a screen, electronic circuits, a microphone, voice recognition circuits which are exchangeable depending upon the context of the verbal data to be received by the calculator and the language in which the data is provided. The calculator is thus responsive to numerals and symbols spoken in a selected language or languages and this is transformed through the circuitry of the calculator to be seen on an elongated display unit. A calculator is also responsi…

A soil cultivating machine comprises a cultivating member having discs and a tined roller, both of which are power-driven. Holes are provided in the discs and the periphery of each disc is divided into plate tine members by recesses. Tines extending from the tined roller extend between adjacent discs. In operation, the discs cut the soil into strips, and these strips are then engaged by tines of the tined roller. Further equipment, such as a seed drill, cultivator, or roller or a combination of …

A mowing machine comprises cutting members which are rotatable about upwardly extending axes and drivable via a change-speed mechanism which enables their speed of rotation to be adjusted, for example to suit the characteristics of the crop being mown. The machine also has crushing member driven via a mechanism having replaceable gears for adjusting speed, said crushing member mounted behind the cutting members to rotate about a horizontal axis and having an adjustable head.

A self-propelled wagon with separate compartments that form a tiltable trough. The compartments have interconnecting outlet ports with slides and individual measuring devices can be located in each compartment. A collector is mounted at the rear of the wagon and a spreader is rotatably positioned beneath the collector for spreading a mixture of materials. Controls or monitors for the slides, tilting mechanism and spreader are located in or adjacent the cab of the wagon.

A time clock and/or computer system has a central management office with readout communication to factory work stations. Work instructions to the work stations are displayed for the foreman who prints or punches a working order. The order together with worker ID are fed to a time clock at the station before and after the job. Signals to a terminal at the station indicate delays to the foreman and management. 2

A mowing machine that extends laterally from a tractor and is an assembly of carrier parts, supporting and spacer housings, normally held together by two tensile bars. In the principal embodiment, the first tensile bar is received through the carrier parts at about the same level as the mower’s drive shaft where the front of the supporting housing curves to form its bottom. The second tensile bar is similarly situated at the rear of the supporting housing about three or four times farther, howev…

A tractor for agricultural purposes, especially for seedbed preparation comprises an engine with a power of at least 30 kilowatt. Further the tractor has a frame (1), at least two power driven wheels (35,40), at least one lifting device (21), and at least one power take-off shaft (55). The weight of the tractor is about 40 kilograms per kilowatt engine power, the engine power is directly transferable to the power take-off shaft of the tractor and the lifting device of the tractor at its coupling…

A soil tilling machine comprising subsoil tilling members, known as subsoilers, which are drivable via a tractor’s PTO around inclined upwardly directed axes. The subsoilers are each primarily constituted by a fowardly and downwardly inclined extending shaft. In front of the tilling members, coulter discs are arranged which cut trenches through which the subsoilers’ shafts can move so that the subsoil is intensively worked and broken up while the surface of the soil is hardly disturbed. A roller…
