An agricultural implement includes a frame and an adjustment system on the frame. The adjustment system includes a first component and a second component connected by a trunnion connection. The trunnion connection includes first and second opposed confronting trunnion blocks, each defining a hole therethrough, the holes being aligned one with the other. A trunnion shaft is disposed in the holes of the trunnion blocks and has ends extending beyond outer surfaces of the trunnion blocks. At least one end of the trunnion shaft defines an opening therethrough. End stops are provided at each end of the trunnion shaft, at least one of the end stops having a portion insertable into the opening. The end stops are larger than the aligned holes to prevent withdrawal of the trunnion shaft from the trunnion blocks.

This invention relates to the lubrication of a wheel support 10. The wheel support 10 comprises support 10 comprises a housing 12 that includes a base portion 14 defining a cavity 16 for receiving therein at least one gear 40, and lubricant for lubricating the gear 40. Opposing first and second arm members 18.1, 18.2 extend respectively from the base portion 14. A free end of each arm member 18.1, 18.2 includes a bearing receiving formation 20.1, 20.2 for receiving therein a bearing. The wheel support 10 further comprises internal lubricant feed means 22, defined in the housing 12, and that extends internally from the base portion 14 into at least one of the arm members 18.1 or 18.2 for feeding lubricant operatively received from a lubricant supply, internally, via the base portion 14, to the bearing receiving formation 20.1 or 20.2 associated with the at least one arm member 18.1 or 18.2.

Systems and methods are provided for eccentric bolt. One embodiment is an eccentric bolt to secure a clevis and lug fitting. The eccentric bolt includes a head and a shank. The shank includes multiple shank sections that successively decrease in diameter in an axial direction from the head toward a tail end of the shank. One of the shank sections is an eccentric shank section that is off-center with respect to a center axis of the shank. The eccentric shank section is configured to engage the lug prior to engagement of concentric shank sections with the clevis. While the eccentric shank section is engaged with the lug, the shank is configured to rotate to align the concentric shank sections with the clevis, and to insert through the clevis and lug fitting to compensate for misalignment of the clevis and lug fitting.

A hinge assembly for an agricultural implement having inner and outer wing frame sections has an inner pivot bracket pivotally coupled to the inner wing frame section at a fold pivot location, and an outer pivot bracket pivotally coupled to the outer wing frame section at a flex pivot location and coupled to the inner pivot bracket. An inner pivot link pivotally couples to the inner pivot bracket and the outer pivot bracket, and an outer pivot link pivotally couples to the outer pivot bracket and the outer wing frame section. The inner and outer pivot brackets pivot relative to each other at the fold pivot location between a working state and a folded state, and the flex pivot location moves relative to the fold pivot location during the relative pivoting. When in the working state, the fold pivot location is higher than a top side of the inner wing frame section and the flex pivot location is lower than a bottom side of the inner wing frame section.

In an example, a compliant shaft enclosure support system for coupling to a shaft enclosure surrounding a shaft includes a bar having a first member slidably coupled to a second member. The bar is oriented along the pitch axis of the shaft. A first bar end of the bar is rotatably connected, around the roll axis and pitch axis of the shaft, to the shaft enclosure at a first connection. A second bar end of the bar is rotatably connected, around the roll axis and pitch axis, to the structure at a second connection. A link is rotatably connected, around the roll axis, at a first link end to the bar, at an intermediate location spaced from the first and second bar ends. The link is rotatably connected, around the pitch axis, at a second link end to the shaft enclosure at a third connection spaced from the first connection.

A gimbal joint may employ a plurality of wear sleeves, each disposed between a pin or pin receptive bore of a first structure and a corresponding bore or pin of a second structure and between another pin or bore of the second structure and a corresponding bore or pin of a third structure. Each of these structures may be adapted to rotate in a single plane, with one structure adapted to also tilt about a first axis, and one other structure adapted to tilt about a second axis. Each integral flanged wear sleeve may comprise a right circular hollow cylindrical body portion, which may be interiorly sized to be retained on one of the pins and externally sized to be retained in one of the pin receptive bores, and a flange portion may radiate from one end of the cylindrical body portion.
