Tillage point for an agricultural implement with improved shank protection
A tillage point for an agricultural implement includes a body extending in a lengthwise direction between a tip end and a retention end and in a vertical direction between an upper body surface and a lower body surface, where the body defines a retention slot between the upper and lower body surfaces. Additionally, the tillage point has a fin extending outwardly from the upper body surface in the vertical direction. The fin defines a height in the vertical direction between a base end of the fin positioned adjacent to the upper body surface of the body and a top end of the fin positioned opposite the base end. The fin further defines a lateral width between opposed lateral sides of the fin, where the lateral width of the fin tapers along at least a portion of the vertical height of the fin.
1. A shank assembly for an agricultural implement, the shank assembly comprising:
a shank extending lengthwise between a proximal end and a distal end, the proximal end configured to be coupled to a frame of the agricultural implement; and
a tillage point coupled to the distal end of the shank, the tillage point including:
a body extending vertically between an upper body surface and a lower body surface and defining a retention slot between the upper and lower body surfaces, the distal end of the shank being received within the retention slot; and
a fin extending vertically from the body along a front side of the shank, the fin defining a vertical height between a base end of the fin positioned adjacent to the upper body surface of the body and a top end of the fin positioned opposite the base end, the fin further defining a lateral width across the front side of the shank between opposed lateral sides of the fin, the fin including a trailing end positioned near a front side of the shank and the fin is spaced apart from the shank and the fin is not in contact with the shank,
wherein the lateral width of the fin tapers along at least a portion of the vertical height of the fin; and
wherein the shank defines a lateral width between a first shank side and a second shank side of the shank, wherein the lateral width of the fin is greater than the lateral width of the shank across the entire height of the fin.
2. The shank assembly of claim 1 , wherein the lateral width of the fin tapers as the fin extends vertically away from the body such that the lateral width at the base end is greater than the lateral width at the top end.
3. The shank assembly of claim 1 , wherein the lateral width of the fin tapers along the entire height of the fin.
4. The shank assembly of claim 1 , wherein the fin includes the trailing end and a leading end opposite the trailing end, the fin defining a length between the leading and trailing ends of the fin, the lateral width of the fin tapering along at least a portion of the length of the fin.
5. The shank assembly of claim 1 , wherein the fin includes the trailing end and a leading end opposite the trailing end, the fin defining a length between the leading and trailing ends of the fin, the length of the fin tapers along at least a portion of the height of the fin.
6. The shank assembly of claim 1 , wherein the body includes a wing positioned on each lateral side of the body, each wing having a greatest width extending away from the body positioned behind the fin and next to the retention slot for the shank.
7. An agricultural implement, the agricultural implement comprising:
a frame configured to be actuated relative to the ground between a raised position and a lowered position;
a shank extending lengthwise between a proximal end and a distal end, the proximal end configured to be coupled to the frame; and
a tillage point coupled to the distal end of the shank, the tillage point including:
a body extending vertically between an upper body surface and a lower body surface and defining a retention slot between the upper and lower body surfaces, the distal end of the shank being received within the retention slot; and
a fin extending vertically from the body along a front side of the shank, the fin defining a vertical height between a base end of the fin positioned adjacent to the upper body surface of the body and a top end of the fin positioned opposite the base end, the fin further defining a lateral width across the front side of the shank between opposed lateral sides of the fin, the fin including a trailing end positioned near a front side of the shank and the fin is spaced apart from the shank and the fin is not in contact with the shank,
wherein the lateral width of the fin tapers along at least a portion of the vertical height of the fin; and wherein the shank defines a lateral width between a first shank side and a second shank side of the shank, the lateral width of the fin being greater than the lateral width of the shank across the entire vertical height of the fin.
8. The agricultural implement of claim 7 , wherein the lateral width of the fin tapers as the fin extends away from the body such that the lateral width at the base end is greater than the lateral width at the top end.
9. The agricultural implement of claim 7 , wherein the body includes a wing positioned on each lateral side of the body, the wing having a greatest width extending away from the body and positioned behind the fin and next to the retention slot for the shank.
10. The agricultural implement of claim 7 , wherein the top end of the fin is configured to extend above the ground when the frame is in the lowered position.
11. The agricultural implement of claim 7 , wherein the fin has a length defined between a leading end and the trailing end, the lateral width of the fin tapering along at least a portion of the length of the fin.
