Abstract: A bearing assembly (10) is taught including a housing (14), a shaft (18) supported within the housing (14) and having an outboard end extending through an opening in an end of the housing (14), a bearing (16) disposed between the shaft (18) and the housing (14) to permit rotation of the shaft (18) within the housing (14); and a harrow engaging member (20), such as a pair of diametrically opposed protrusions or a pair of apertured plates, mounted on the housing (14) and positioned either a) diametrically adjacent the bearing or b) between the bearing and the outboard end of the shaft. A harrow including the bearing assembly (10) is also taught.

Abstract: A row-crop cultivator for tilling the soil between adjacent rows of crops is connected to a prime mover. The cultivator includes a drawbar connected to the prime mover and a plurality of laterally adjacent cultivating gang assemblies for tilling the soil between adjacent crop rows, each is connected to the drawbar so that it travels on the ground under its own weight and moves independently in a vertical direction relative to an adjacent gang assembly.
