Seed firmer
Embodiments of the present disclosure relate to a seed firmer having a resilient portion and a firming portion that are molded together into a unitary part with each portion being a different material.
1. A seed firmer comprising:
a resilient portion for attaching to an agricultural implement, wherein the resilient portion has a first portion for attaching to the agricultural implement and a second portion; and
a firming portion having a width for contacting seeds in a seed trench, wherein the resilient portion and the firming portion are each made from different materials with the firming portion being made of polyethylene, wherein the firming portion is molded over the second portion of the resilient portion to form a unitary seed firmer and extends along a length of the second portion of the resilient portion that is equal to or greater than a length of the first portion, and wherein the second portion of the resilient portion has a width that is 30 to 70% of a width of the first portion of the resilient portion.
2. The seed firmer of claim 1 , wherein the resilient portion is made from PA6 nylon.
3. The seed firmer of claim 1 , wherein the firming portion is made from ultra high molecular weight polyethylene.
4. The seed firmer of claim 1 , wherein the firming portion is disposed at 30 to 70% of the length of the seed firmer.
5. The seed firmer of claim 1 , wherein the firming portion is disposed at 40 to 60% of the length of the seed firmer.
6. The seed firmer of claim 1 , wherein the firming portion is disposed at 45 to 55% of the length of the seed firmer.
7. The seed firmer of claim 1 , wherein the firming portion is disposed at 50% of the length of the seed firmer.
8. The seed firmer of claim 1 , wherein the second portion has a width that is 40 to 60% of a width of the first portion.
9. The seed firmer of claim 1 , wherein the second portion has a width that is 45 to 55% of a width of the first portion.
10. The seed firmer of claim 1 , wherein the second portion has a width that is 50% of a width of the first portion.
11. The seed firmer of claim 1 , wherein the seed firmer further comprises a channel.
12. The seed firmer of claim 1 , wherein the resilient portion further comprises at least one post.
13. The seed firmer of claim 1 , wherein the resilient portion further comprises a bracket.
14. The seed firmer of claim 1 , wherein the width of the firming portion, the width of the first portion of the resilient portion, and the width of the second portion of the resilient portion are aligned with a lateral width of the seed trench.
