ABSTRACT:
A tillage sweep assembly includes a base sweep with a central fore-and-aft slot. A support strap or stem includes a corresponding fore-and-aft extending protrusion which mates with the slot. A filet weld connects the top of the base sweep to the support strap with the weld extending around the strap. A plug weld is added to the underside of the sweep in an offset or lifted portion of the bottom of the base sweep above the cutting plane of the sweep. The extra plug weld adds strength to the existing filet weld joint and significantly reduces the chance of inadvertent base sweep loss. The location of the plug weld above the cutting plane protects the plug weld from wear. The strap or step of the sweep assembly is slotted for ease of pitch adjustment, and the base sweep has wings with substantial fore-and-aft extending end portions to retain working width over the life of the sweep.
