Toolbar implement

摘要

A toolbar implement connects to a tractor and a plurality of row units are connected to the toolbar implement. The toolbar implement contains: (a) a main longitudinal frame; (b) a transverse left wing toolbar hingedly connected to the frame; (c) a transverse center bar connected to the frame; (d) a transverse right wing toolbar hingedly connected to the frame; (e) a plurality of lift arms connected to the center bar; (f) an axle connected to the distal ends of the lift arms; (g) a plurality of track assemblies mounted on the axle; (h) a left longitudinal frame member connected to the center bar and extending rearwardly; (i) a right longitudinal frame member connected to the center bar and extending rearwardly; and (j) a transverse center toolbar connected to the main frame, the left longitudinal frame member, and the right longitudinal frame member.

1. A toolbar implement for connection to a tractor and to which a plurality of row units are connected, the toolbar implement comprising:
(a) a longitudinal main frame having a front connector for connection to a tractor hitch; (b) a left wing toolbar hingedly connected to the main frame and movable between a longitudinal folded position and a transverse working position, the left wing toolbar having an outer end; (c) a right wing toolbar hingedly connected to the main frame and movable between a longitudinal folded position and a transverse working position, the right wing toolbar having an outer end with a distance between the outer end of the right wing toolbar and the outer end of the left wing toolbar defining an overall working width of the toolbar implement; (d) a transverse center bar connected to the main frame and being completely aft of the left wing toolbar and the right wing toolbar; (e) a plurality of lift arms with upper proximate ends and lower distal ends, the lift arms connected at their proximate ends to the center bar; (f) an axle connected to the distal ends of the lift arms and having no direct connection to the main frame so that the axle is free to move independently of the main frame; (g) a plurality of track assemblies mounted on the axle, the track assemblies being completely aft of the left wing toolbar and the right wing toolbar; (h) a left longitudinal frame member connected to the center bar and extending aftward of the center bar; (i) a right longitudinal frame member connected to the center bar and extending aftward of the center bar; and (j) a transverse center toolbar connected to the main frame, the left longitudinal frame member, and the right longitudinal frame member, the center toolbar being completely aft of the track assemblies so that the track assemblies do not interfere with any row units connected to the center toolbar, and the center toolbar extending at least to the track assemblies so that row units can be connected to the left wing toolbar, the right wing toolbar, and the center toolbar at any point along the overall working width of the toolbar implement.
