Abstract
Abstract A combine of the type designed to harvest grain-type crops and including a self-propelled chassis having adjustably mounted thereon at least one axle capable of being selectively positioned in either of two operative positions which are arranged substantially perpendicular to one another thereby allowing the combine to be driven in a direction either substantially parallel to or perpendicular to its longitudinal axis. The adjustable axle may be a drive axle and also may be steerable by various linkage attached to the steering mechanism. A second supporting axle may be removably attached to the combine frame in a corresponding position relative to the operative position in which the adjustable or drive axle is located.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
108 words
A combine structure of the type having a substantially larger dimension along the longitudinal axis then along the transverse axis thereof, said structure comprising: a frame, a drive axle movably mounted on said frame, a substantially vertically oriented pin connected to said drive axle and said frame, said drive axle movably mounted relative to said frame to rotate about a substantially vertical axis of said pin, whereby said drive axle is movable into and out of at least two operative positions disposed at substantially right angles to one another and the primary direction of travel of said combine is defined by the operative position of said drive axle.
Claim 2
Dependent Claim
108 words
A combine structure of the type having a substantially larger dimension along the longitudinal axis then along the transverse axis thereof, said structure comprising: a frame, a drive axle movably mounted on said frame, a substantially vertically oriented pin connected to said drive axle and said frame, said drive axle movably mounted relative to said frame to rotate about a substantially vertical axis of said pin, whereby said drive axle is movable into and out of at least two operative positions disposed at substantially right angles to one another and the primary direction of travel of said combine is defined by the operative position of said drive axle.
Claim 3
Dependent Claim
50 words
A combine structure as in claim 1 further including support means interconnected between said combine frame and said drive axle, aid support means being movable relative to both said combine frame and said drive axle so as to permit variation of distance between said combine frame and said drive axle.
Claim 4
Dependent Claim
27 words
A combine structure as in claim 2 wherein said support means comprises a plurality of piston and cylinder assemblies interconnected between said drive axle and said combine.
Claim 5
Dependent Claim
66 words
A combine structure as in claim 3 further comprising conduit means connected to each of said cylinders of said piston and cylinder assemblies such that said cylinders are interconnected in fluid communicating relation to one another, whereby said support means serves to automatically vary the space between said drive axle and said frame dependent upon the contour of the ground on which said combine is traveling.
Claim 6
Dependent Claim
39 words
A combine structure as in claim 1 further comprising steering linkage means connected to said drive axle, said linkage mounted on said combine frame so as to be operatively connected to said axle in either of said two positions.
Claim 7
Dependent Claim
55 words
A combine structure as in claim 1 further comprising support wheels assembly means removably connected in one of a plurality of positions on said combine frame, said support wheel assembly positioned in cooperative relation to said drive axle, whereby the position of said support wheel assembly is dependent upon the position of said drive axle.
Claim 8
Dependent Claim
47 words
A combine structure as in claim 6 wherein said support wheels assembly means are disposed in front of said drive axle assembly, relative to the primary direction of travel of said combine, when said drive axle is arranged substantially parallel to the longitudinal axis of said combine.
Claim 9
Dependent Claim
45 words
A combine structure as in claim 6 wherein said support wheel assembly means is disposed rearwardly of said drive axle, relative to the primary direction of travel of said combine, when said drive axle is disposed substantially parallel to the transverse axis of said combine.
Claim 10
Dependent Claim
35 words
A combine structure as in claim 1 further comprising a cutter bar, hinge means interconnecting said cutter bar to said combine so as to allow said cutter bar to be selectively positioned in inoperative position.
Claim 11
Dependent Claim
42 words
A combine structure as in claim 1 further comprising a harvesting reel rotatably mounted in substantially parallel relation relative to the longitudinal axis of said combine and pivotally connected to said combine, whereby said reel can be pivoted out of operative position.
