Wheel assembly for an agricultural implement

A wheel assembly for an agricultural implement, comprising:

• a wheel;
• and
• a linkage assembly comprising:
• a mount configured to be non-rotatably coupled to a toolbar of the agricultural implement;
• a first link pivotally coupled to the mount;
• a second link pivotally coupled to the mount;
• and
• a wheel support pivotally coupled to the first link and to the second link, wherein the wheel is rotatably coupled to the wheel support at a wheel pivot;
• wherein the linkage assembly is configured to control movement of the wheel between a working position and a transport position, the linkage assembly is configured to position the wheel pivot farther from the toolbar along a vertical axis while the wheel is in the transport position, the linkage assembly is configured to position the wheel pivot closer to the toolbar along the vertical axis while the wheel is in the working position, the linkage assembly is configured to position the wheel pivot forward of a longitudinal centerline of the toolbar while the wheel is in the working position, and the linkage assembly is configured to position the wheel pivot at or rearward of the longitudinal centerline of the toolbar while the wheel is in the transport position.

An agricultural implement, comprising:

• a toolbar configured to support a plurality of row units;
• and
• a wheel assembly, comprising:
• a wheel;
• and
• a linkage assembly comprising:
• a mount non-rotatably coupled to the toolbar;
• a first link pivotally coupled to the mount;
• a second link pivotally coupled to the mount;
• and
• a wheel support pivotally coupled to the first link and to the second link, wherein the wheel is rotatably coupled to the wheel support at a wheel pivot;
• wherein the linkage assembly is configured to transition between a raised position and a lowered position to control a vertical position of the wheel pivot relative to the toolbar, the linkage assembly is configured to position the wheel pivot at a first longitudinal location forward of a longitudinal centerline of the toolbar while in the raised position, the linkage assembly is configured to position the wheel pivot at a second longitudinal location at or rearward of the longitudinal centerline of the toolbar while in the lowered position, and the linkage assembly is configured to move the wheel pivot from the first longitudinal location to the second longitudinal location in response to transitioning from the raised position to the lowered position.
