Abstract:
1. A coulter assembly, comprising: a support structure; a coulter disk rotatably mounted to the support structure and configured to cut a trench into soil; a swing arm comprising a first region and a second region, the swing arm being rotatably mounted to a first side of the support structure in the first region; a gauge wheel rotatably mounted to the second region of the swing arm and configured to limit a penetration depth of the coulter disk into the soil based on an angle of the swing arm with respect to the support structure; and a depth adjustment assembly mounted to a second side of the support structure, opposite the first side, and comprising a lever having a first end and a second end, the first end being rigidly coupled to the first region of the swing arm by a shaft that passes through the support structure, and the second end being rotatably coupled to a continuously variable linear actuator, wherein extension and retraction of the continuously variable linear actuator facilitates rotation of the swing arm with respect to the support structure; wherein the depth adjustment assembly is configured to adjust the penetration depth of the coulter disk by adjusting a position of a gauge wheel relative to the support structure along a continuous range.
