Abstract

A frame assembly for an agricultural implement includes a frame having laterally opposite first and second sides, a first arm disposed at the first side and configured to rotate relative to the frame, a first biasing member coupled to the first side and to the first arm, a second arm disposed at the second side and configured to rotate relative to the frame, and a second biasing member coupled to the second side and the second arm. The first and second arms are configured to couple to the agricultural implement and to enable the agricultural implement to rotate about a longitudinal axis via rotation of the first arm and rotation of the second arm. The first and second biasing members are configured to flex in response to the rotation of the first and second arms, respectively.

Dependent claims

A frame assembly for an agricultural implement, comprising:

a frame having a first side and a second side disposed laterally opposite the first side;
a first arm disposed at the first side of the frame and configured to rotate relative to the frame;
a first biasing member coupled to the first side of the frame and to the first arm;
a second arm disposed at the second side of the frame and configured to rotate relative to the frame;
and
a second biasing member coupled to the second side of the frame and the second arm;
wherein the first arm and the second arm are configured to couple to the agricultural implement and to enable the agricultural implement to rotate about a longitudinal axis via rotation of the first arm and rotation of the second arm, and the first biasing member and the second biasing member are configured to flex in response to the rotation of the first arm and the rotation of the second arm, respectively;
and
wherein the first arm and the second arm each comprise:
a first longitudinal portion configured to couple to the agricultural implement;
and
a second longitudinal portion configured to couple to the first biasing member or the second biasing member, wherein the second longitudinal portion extends parallel to the first longitudinal portion.

An agricultural implement assembly, comprising:

an agricultural implement frame comprising:
a first lateral portion;
a second lateral portion disposed opposite the first lateral portion;
and
a central portion disposed between the first lateral portion and the second lateral portion;
and
an intermediate frame assembly comprising:
an intermediate frame having a first side and a second side disposed laterally opposite the first side;
a first arm disposed at the first side of the intermediate frame and directly rotatably coupled to the intermediate frame, wherein the first arm is rotatably coupled to the central portion of the agricultural implement frame;
a first biasing member coupled to the first side of the intermediate frame and the first arm;
a second arm disposed at the second side of the intermediate frame and directly rotatably coupled to the intermediate frame, wherein the second arm is rotatably coupled to the central portion of the agricultural implement frame;
and
a second biasing member coupled to the second side of the intermediate frame and the second arm;
wherein the agricultural implement frame is configured to rotate about a longitudinal axis relative to the intermediate frame via the first arm, the first biasing member, the second arm, and the second biasing member.
