Abstract
Abstract Agricultural machine having a frame supported by driving wheels and supporting wheels, said frame having a main part arranged in the longitudinal direction of the machine so as to extend from the region of the driver''s station in the machine, preferably from the upper side thereof, over coupling means for agricultural implements and to a unit including the supporting wheels and coupling means of the machine. Said agricultural machine includes a driver''s station lodged in a cabin immediately before the driving wheel axle. To permit coupling and uncoupling of working implements said agricultural machine is adapted to pivot about the driving wheel axle whereby said machine resting on the driving wheels and on wheels mounted in the free ends of hydraulically operated swinging arms can be run with the supporting wheels lifted up over the working implement which, after the said machine has swung back to normal position, is coupled to the coupling means between the driving wheels and the supporting wheels.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
139 words
An agricultural machine having a frame, driving wheels and supporting wheels supporting the frame, a driving unit coupled to the driving wheels, a driver''s station having means for controlling the driving unit, said frame including a substantially vertical front portion attached to said supporting wheels, a coupling means for agricultural implements fixed to the lower end of the front portion, said coupling means being situated between the supporting wheels and the driving wheels, said frame including a rear portion to which the driving unit and the driving wheels are attached, said driver''s station situated forward of the rear portion, said frame having an intermediate portion in the form of a unitary beam having a front end connected to the upper end of the front portion and a rear end rigidly connected tO the rear portion above the driver''s station.
Claim 2
Dependent Claim
139 words
An agricultural machine having a frame, driving wheels and supporting wheels supporting the frame, a driving unit coupled to the driving wheels, a driver''s station having means for controlling the driving unit, said frame including a substantially vertical front portion attached to said supporting wheels, a coupling means for agricultural implements fixed to the lower end of the front portion, said coupling means being situated between the supporting wheels and the driving wheels, said frame including a rear portion to which the driving unit and the driving wheels are attached, said driver''s station situated forward of the rear portion, said frame having an intermediate portion in the form of a unitary beam having a front end connected to the upper end of the front portion and a rear end rigidly connected tO the rear portion above the driver''s station.
Claim 3
Dependent Claim
27 words
An agricultural machine as claimed in claim 1, having a cabin arranged under the intermediate portion of the frame, said driver''s station being located in the cabin.
Claim 4
Dependent Claim
26 words
An agricultural machine as claimed in claim 1, wherein the driver''s station is located adjacent the driving wheels on the side thereof facing the supporting wheels.
Claim 5
Dependent Claim
33 words
An agricultural machine as claimed in claim 3, wherein the driving wheels have an axle, and the driver''s station has a seat positioned on practically the same level as the driving wheel axle.
Claim 6
Dependent Claim
71 words
An agricultural machine as claimed in claim 1, wherein the supporting wheels and the coupling means together with the front portion of the frame comprise a unit, means connecting the front portion of the frame for lateral movement and for adjustable movement along the intermediate portion of the frame in a direction toward and away from the driver''s station, said driver''s station being suspended in the rear portion of the frame.
Claim 7
Dependent Claim
87 words
An agricultural machine as claimed in claim 5, wherein said unit includes a lifting frame with two yoke-shaped arms movable between a raised position and a lower position by a hydraulic means, each of said arms having one end pivotally attached to the lower part of said front portion of the frame and another end provided with slots, a vertical lifting frame having a horizontal rod extending therefrom, said rod being received in said slots, said slots being vertical when the arms are in the lower position.
Claim 8
Dependent Claim
36 words
An agricultural machine as claimed in claim 6, having a link with one end pivotally attached to the upper end of the lifting frame and another end pivotally attached to the front portion of the frame.
Claim 9
Dependent Claim
150 words
An agricultural machine having a frame supported by driving wheels and supporting wheels, a driving unit coupled to the driving wheels, said frame comprising a substantially vertical front portion having a lower end to which the supporting wheels are fixed, coupling means for agricultural implements situated between the supporting wheels and the driving wheels, a rear portion of the frame to which the driving unit and the driving wheels are fixed, and an intermediate portion of the frame connecting said front portion and said rear portion, the machine further comprising a lifting device having a further wheel located between said supporting wheels and said driving wheels, power unit means for pressing said further wheel against the ground to swing the machine vertically about the driving wheels, thereby allowing the machine to be driven with the supporting wheels passing over an implement to be coupled or uncoupled on the coupling means.
Claim 10
Dependent Claim
150 words
An agricultural machine having a frame supported by driving wheels and supporting wheels, a driving unit coupled to the driving wheels, said frame comprising a substantially vertical front portion having a lower end to which the supporting wheels are fixed, coupling means for agricultural implements situated between the supporting wheels and the driving wheels, a rear portion of the frame to which the driving unit and the driving wheels are fixed, and an intermediate portion of the frame connecting said front portion and said rear portion, the machine further comprising a lifting device having a further wheel located between said supporting wheels and said driving wheels, power unit means for pressing said further wheel against the ground to swing the machine vertically about the driving wheels, thereby allowing the machine to be driven with the supporting wheels passing over an implement to be coupled or uncoupled on the coupling means.
Claim 11
Dependent Claim
70 words
An agricultural machine as claimed in claim 8, wherein said lifting device comprises two swing arms pivotally connected at their rear ends to said rear portion of the frame and provided with said further wheels in their forward ends, said power unit means including at least one hydraulic cylinder piston unit connected to said swing arms for pressing the wheels against the ground when the cylinder piston unit is actuated.
