An agricultural tillage implement includes a frame member and at least one rolling basket assembly coupled to the frame member. The rolling basket assembly has at least one bearing hanger, at least one rolling basket and at least one bearing assembly rotationally coupling the rolling basket to the bearing hanger. The bearing assembly has a bearing with an inner ring and a spindle holding the inner ring. The spindle is coupled to the bearing hanger. The spindle being configured to accommodate dynamic misalignment of the bearing.

A mounting structure for mounting a pivot arm to an implement has a cylindrical member, an adjusting sleeve, and a mounting bolt extending through the cylindrical member and adjusting sleeve to fix the cylindrical member and adjusting sleeve together. The cylindrical member extends through a bore of a bearing housing for rotation within the bearing housing. The adjusting sleeve has a threaded external surface. A disc spring is positioned on the adjusting sleeve. An adjusting nut is threaded onto the threaded external surface of the adjusting sleeve. The adjusting nut can be tightened to compress the disc spring to create a lateral bearing force against the bearing housing. The bearing housing can be integral with a pivot arm for mounting a gauge wheel assembly on a planter row unit, or the bearing housing can be a fixed part for mounting a pivot arm for a closing/press wheel on a drill.

A system for detecting bearing failures for disk gang assemblies of an agricultural implement includes a disk gang assembly having a shaft, a bearing rotatably supporting the shaft for rotation about a rotational axis, and a plurality of disks supported on the shaft for rotation with the shaft about the rotational axis. The system further includes a sensor provided in operative association with the bearing, with the sensor generating data indicative of a bearing-related parameter. The system may additionally include a computing system configured to receive the data generated by the sensor, convert the data to a frequency domain using a spectral analysis technique, and identify when the bearing is experiencing a bearing failure condition based at least in part on an evaluation of the data converted to the frequency domain.
