Agricultural row unit accessory
A tool assembly for a planter row unit resides at the forward end of the row unit beneath the tool bar. The assembly includes a bracket assembly connected to the row unit, with a ground engaging tool removably mounted on the bracket assembly for movement between raised and lowered positions. A linear actuator controls the position of the tool. The tool may also include a depth control mechanism. Different tools can be interchanged on the bracket assembly.
1. A planter row unit comprising:
a frame with at least one disc opener, at least one gauge wheel, and at least one closing wheel;
a bracket assembly mounted forwardly of the frame;
a set of upper link arms and a set of lower link arms all pivotally extending from the bracket assembly for pivotal movement in unison; and
a tool mounted to the set of lower link arms below the bracket assembly and in front of the frame.
2. The planter row unit of claim 1 wherein the tool is pivotal between raised and lowered positions.
3. The planter row unit of claim 2 further comprising a linear actuator attached to the bracket assembly to move the tool between the raised and lowered positions.
4. The planter row unit of claim 1 wherein the tool includes a height control mechanism.
5. The planter row unit of claim 1 wherein the tool is mounted to the bracket assembly using hooks.
6. The planter row unit of claim 5 further comprising a removable retention pin to preclude unhooking of the bracket assembly.
7. The planter row unit of claim 1 wherein the tool includes at least one gauge wheel.
8. The planter row unit of claim 7 wherein the at least one gauge wheel is height adjustable.
9. The planter row unit of claim 1 wherein the tool is centered longitudinally on the planter row unit.
10. The planter row unit of claim 1 wherein the tool is selected from a set comprising a debris cleaner, a fertilizer applicator, a rolling basket, coulters, and crop rollers.
11. The planter row unit of claim 1 wherein the set of upper arms are curved.
12. The planter row unit of claim 1 wherein the set of upper arms are L-shaped.
13. The planter row unit of claim 1 further comprising a linear actuator to adjust the height of the tool.
14. The planter row unit of claim 13 wherein the linear actuator is operatively connected to the bracket assembly.
15. The planter row unit of claim 1 wherein the bracket assembly is adapted to mount to a tool bar, such that the tool is adapted to reside below the tool bar.
16. The planter row unit of claim 1 wherein the tool is movable between the raised and lowered positions independently from the frame.
17. The planter row unit of claim 1 further comprising a receiver pivotally connected to the sets of upper and lower arms and the tool being mounted to the receiver.
18. The planter row unit of claim 1 wherein each arm of the sets of upper and lower link arms has forward and rearward ends, and is pivotal about the forward and reward ends.
19. The planter row unit of claim 1 wherein the set of upper link arms includes a pair of laterally offset arms.
20. The planter row unit of claim 1 wherein the set of lower link arms includes a pair of laterally offset arms.
