Abstract
Abstract An elongated bar soil working apparatus constructed so that a plurality of bars are supported in a parallel relationship for rotation in one or more horizontal planes and positioned closely adjacent each other whereby the corners of one bar will cooperate with the corners of an adjacent bar to effect a severing action on vines or other foliage moving therebetween whereby the bars are self-cleaning. Power drives are operatively associated with the bars for syncronous rotation of the bars whereby the corners of the bars will be simultaneously advanced through a common plane in closely positioned relationship to effect the severing action on the vines and other foliage located therebetween and prevent vine and foliage build up on the bars. The present apparatus includes a frame which will allow the apparatus to be removably supported by conventional tractor operable tool bar whereby the bars can be advanced through the soil to perform plant uprooting or other soil working operations.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
105 words
Crop uprooting and soil working apparatus comprising: (a) at least two elongated bars, said bars being shaped to define at least one angled edge thereon; (b) means supporting said at least two bars in parallel relationship with said bars shaped to define said angled edges being in sufficient close proximity to cooperate to sever vines and other foliage moving therebetween; and (c) means for effecting rotation of said bars whereby said bars uproot crops and work soil during advancement, and said angled cutting edges cyclically advance into cooperation with said adjacent bar to effect severing of vines and foliage therebetween, whereby said apparatus is self-cleaning.
Claim 2
Dependent Claim
105 words
Crop uprooting and soil working apparatus comprising: (a) at least two elongated bars, said bars being shaped to define at least one angled edge thereon; (b) means supporting said at least two bars in parallel relationship with said bars shaped to define said angled edges being in sufficient close proximity to cooperate to sever vines and other foliage moving therebetween; and (c) means for effecting rotation of said bars whereby said bars uproot crops and work soil during advancement, and said angled cutting edges cyclically advance into cooperation with said adjacent bar to effect severing of vines and foliage therebetween, whereby said apparatus is self-cleaning.
Claim 3
Dependent Claim
20 words
Apparatus as defined in claim 1 wherein two bars are provided, both of said bars being supported for syncronous rotation.
Claim 4
Dependent Claim
21 words
Apparatus as defined in claim 1 wherein both of said bars are square in cross section to define four angled edges.
Claim 5
Dependent Claim
18 words
Apparatus as defined in claim 3 wherein both of said bars are in the same general horizontal plane.
Claim 6
Dependent Claim
30 words
Apparatus as defined in claim 1 wherein said bars are supported at opposite ends by a pair of support standards, one of said bars being drivingly supported at each standard.
Claim 7
Dependent Claim
21 words
Apparatus as defined in claim 1 wherein said means for effecting rotation of said bars is associated with said support means.
Claim 8
Dependent Claim
33 words
Apparatus as defined in claim 6 wherein said means for effecting rotation of said bars comprises hydraulic motor means having releasable couplings which can be operatively associated with a tractor hydraulic drive system.
Claim 9
Dependent Claim
30 words
Apparatus as defined in claim 1 wherein said support means for said bars includes clamp means, whereby said apparatus can be removably mounted on conventional tractor supported tool bar means.
Claim 10
Dependent Claim
130 words
Crop uprooting and soil working apparatus comprising: (a) a pair of vertically oriented, horizontally spaced support standards, with each standard including means located adjacent an upper edge of said standards for attachment to a transport means; (b) a pair of shaped bars rotatably supported by said standards in parallel relationship in a horizontal plane, said bars having angled edges thereon, and being located proximate each other to permit angled edges of same to sever foliage passing therebetween; and (c) drive means for said bars supported on said standards for syncronally rotating said bars whereby advancement of said bars beneath the surface of a crop bed will effect an uprooting of plants grown on said bed, and severing of foliage between said bars will preclude foliage build up around said bars.
Claim 11
Dependent Claim
130 words
Crop uprooting and soil working apparatus comprising: (a) a pair of vertically oriented, horizontally spaced support standards, with each standard including means located adjacent an upper edge of said standards for attachment to a transport means; (b) a pair of shaped bars rotatably supported by said standards in parallel relationship in a horizontal plane, said bars having angled edges thereon, and being located proximate each other to permit angled edges of same to sever foliage passing therebetween; and (c) drive means for said bars supported on said standards for syncronally rotating said bars whereby advancement of said bars beneath the surface of a crop bed will effect an uprooting of plants grown on said bed, and severing of foliage between said bars will preclude foliage build up around said bars.
Claim 12
Dependent Claim
14 words
Apparatus as defined in claim 9 wherein said bars are square in cross section.
Claim 13
Dependent Claim
40 words
Apparatus as defined in claim 9 wherein said support standards are boxed housings, one of said bars being drivingly supported in one of said standards and the other of said bars being drivingly supported in the other of said standards.
Claim 14
Dependent Claim
41 words
Apparatus as defined in claim 9 wherein said drive means comprises a hydraulic motor means for both of said bars, said hydraulic motor being associated with a single drive shaft, said shaft being drivingly connected to one end of each bar.
