Claims Analysis

Total Claims: 17
Claim 1
Independent Claim 120 words
A cultivator comprising a frame and coupling means for attachment to a tractor, a plurality of side-by-side soil-working members supported on said frame in a row transverse to the direction of travel, said soil working members being rOtatable about upwardly extending axes and being drivenly connected to drive means and a source of power, said soil-working members each having generally vertically extending tine means with striking tools releasably connected to the tine means of at least one of said soil-working members, with clamping means, said clamping means and striking tools being slideable and adjustable vertically, along the lengths of said tine means whereby vegetation can be cut at selected heights by said striking tools during operation of said soil-working members.
Claim 2
Dependent Claim 120 words
A cultivator comprising a frame and coupling means for attachment to a tractor, a plurality of side-by-side soil-working members supported on said frame in a row transverse to the direction of travel, said soil working members being rOtatable about upwardly extending axes and being drivenly connected to drive means and a source of power, said soil-working members each having generally vertically extending tine means with striking tools releasably connected to the tine means of at least one of said soil-working members, with clamping means, said clamping means and striking tools being slideable and adjustable vertically, along the lengths of said tine means whereby vegetation can be cut at selected heights by said striking tools during operation of said soil-working members.
Claim 3
Dependent Claim 54 words
A cultivator as claimed in claim 1, wherein said tine means includes a pair of tines secured to every third soil-working member of said row with striking tools connected to each tine, the remaining soil-working members having their tines removed, whereby the striking tools can be rotated along horizontal paths below said soil-working members.
Claim 4
Dependent Claim 45 words
