Abstract
Abstract An apparatus is disclosed for harvesting a ground crop having a stalk such as asparagus. The apparatus includes a flat blade having a holding slot for the stalks being cut located above the cutting edge. The stalks may be held in a queue in the slot until such time as a sufficient collection of stalks has accumulated for unloading. The apparatus is designed as a hand tool which may be used in such a manner to avoid bending over while harvesting the stalks.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
186 words
An apparatus for harvesting a ground crop having a stalk, such as asparagus spears, said apparatus comprising: means for cutting said stalk at ground level, said cutting means consisting of a sharpened leading edge formed of a substantially flat metal plate; and means for holding said stalk in a queue, said stalk holding means consisting of metal plate materials defining a slot adjacent said cutting means for holding said stalk queue, said slot defining means having a stalk entry end forward of said sharpened leading edge, a stalk exit end rearward of said cutting means and a path between said entry end and said exit end of approximately the width of a stalk, said entry end being substantially wider than a stalk width for capturing said stalk in said queue prior to cutting of said stalk, said exit end being open to permit rearward withdrawal of a collection of each said stalk through said queue, said slot defining means being fixedly positioned relative to said cutting means to receive and hold each said stalk in said queue upon cutting of said stalk by said cutting means.
Claim 2
Independent Claim
186 words
An apparatus for harvesting a ground crop having a stalk, such as asparagus spears, said apparatus comprising: means for cutting said stalk at ground level, said cutting means consisting of a sharpened leading edge formed of a substantially flat metal plate; and means for holding said stalk in a queue, said stalk holding means consisting of metal plate materials defining a slot adjacent said cutting means for holding said stalk queue, said slot defining means having a stalk entry end forward of said sharpened leading edge, a stalk exit end rearward of said cutting means and a path between said entry end and said exit end of approximately the width of a stalk, said entry end being substantially wider than a stalk width for capturing said stalk in said queue prior to cutting of said stalk, said exit end being open to permit rearward withdrawal of a collection of each said stalk through said queue, said slot defining means being fixedly positioned relative to said cutting means to receive and hold each said stalk in said queue upon cutting of said stalk by said cutting means.
Claim 3
Dependent Claim
28 words
The apparatus according to claim 1 wherein said cutting means includes means defining a void disposed trailing said leading edge to permit passage of debris past said blade.
Claim 4
Dependent Claim
48 words
The apparatus according to claim 2 wherein said exit end is spaced further from said cutting means than said entry end closest to said leading edge for drawing each said stalk away from said cutting means as each said stalk is advanced along said path in said slot.
Claim 5
Dependent Claim
54 words
The apparatus according to claim 3 wherein said holding means includes means forming first and second spars, said first and second spars attaching said holding means to said cutting means with flexure only at opposing lateral margins to permit said slot forming means to spread laterally as said stalks are stacked in said queue.
Claim 6
Dependent Claim
183 words
In an apparatus for harvesting a ground crop having a stalk, such as asparagus spears, said apparatus including spade-like means for cutting said stalk at ground level, the improvement comprising: means to be fixedly attached to said spade-like means for holding said stalk in a queue, said stalk holding means consisting of metal plate materials defining a slot adjacent said cutting means for holding said stalk queue, said slot defining means having a stalk entry end forward of said sharpened leading edge, a stalk exit end rearward of said cutting means and a path between said entry end and said exit end of approximately the width of a stalk, said entry end being substantially wider than a stalk width for capturing said stalk in said queue prior to cutting of said stalk, said exit end being open to permit rearward withdrawal of a collection of each said stalk through said queue, said slot defining means being fixedly positioned relative to said cutting means to receive and hold each said stalk in said queue upon cutting of said stalk by said spade-like cutting means.
Claim 7
Dependent Claim
183 words
In an apparatus for harvesting a ground crop having a stalk, such as asparagus spears, said apparatus including spade-like means for cutting said stalk at ground level, the improvement comprising: means to be fixedly attached to said spade-like means for holding said stalk in a queue, said stalk holding means consisting of metal plate materials defining a slot adjacent said cutting means for holding said stalk queue, said slot defining means having a stalk entry end forward of said sharpened leading edge, a stalk exit end rearward of said cutting means and a path between said entry end and said exit end of approximately the width of a stalk, said entry end being substantially wider than a stalk width for capturing said stalk in said queue prior to cutting of said stalk, said exit end being open to permit rearward withdrawal of a collection of each said stalk through said queue, said slot defining means being fixedly positioned relative to said cutting means to receive and hold each said stalk in said queue upon cutting of said stalk by said spade-like cutting means.
Claim 8
Dependent Claim
48 words
The apparatus according to claim 5 wherein said exit end is spaced further from said cutting means than said entry end closest to said leading edge for drawing each said stalk away from said cutting means as each said stalk is advanced along said path in said slot.
Claim 9
Dependent Claim
48 words
The apparatus according to claim 5 wherein said holding means includes means forming first and second spars attaching said holding means to said cutting means with flexure at opposing lateral margins to permit said slot forming means to spread laterally as said stalks are stacked in said queue.
