First Claim
Patent Images
1. A seed planting assembly comprising:
- a laterally extending support member;
a planting unit including a planting unit frame supported by the support member, wherein the planting unit frame carries;
i. a seed trench opening assembly operable to create a seed trench in a ground surface;
ii. a seed delivery assembly delivering seeds into the seed trench;
iii. a seed trench closing assembly operable to close the seed trench; and
iv. a depth regulating member having a vertical position relative to the seed trench opening assembly, the depth regulating member being supported by an arm that is coupled to the planting unit frame; and
v. a shock absorbing member coupled to the arm that absorbs forces caused by obstructions encountered by the depth regulating member during a planting operation.

Abstract
A planting unit is provided having a seed trench opener that forms a seed trench in a ground surface as the planting unit travels along the ground. A depth regulating member is provided that has a predetermined vertical position relative to the opener. The depth regulating member is operable to ride along the ground and thus predetermined the seed trench depth. A suspension assembly is provided to reduce the shock forces on the planting unit when obstacles are encountered. Furthermore, a suspension system is provided to the seed trench opener, in addition to the depth regulating member.

17. A seed planting assembly supported by a frame, the assembly comprising:
-
a seed trench opening assembly operable to create a seed trench in a ground surface;
a seed delivery assembly delivering seeds into the seed trench;
a seed trench closing assembly operable to close the seed trench, the seed trench closing assembly supported by a first arm having a lower segment connected to the frame and an upper segment extending upwards therefrom; and
a depth regulating member having a vertical position relative to the seed trench opening assembly, the depth regulating member being supported by a second arm having a lower segment connected to the frame and an upper segment extending upwards therefrom; and
a shock absorbing member connected between the upper segments of the first and second arms. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24)

25. A method for operating a planting unit including a planting unit frame supporting a seed trench opening assembly and a depth regulating member being supported by an arm that is coupled to the planting unit, wherein the depth regulating member has a vertical position relative to the seed trench opening assembly, the method comprising the step of:
coupling a shock absorbing member to the arm, wherein forces caused by obstructions encountered by the depth regulating member during a planting operation are absorbed by the shock absorbing member. - View Dependent Claims (26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40)
