ABSTRACT:
An implement has a hollow frame portion and tool means on shafts journalled for rotation on the frame portion. The upper ends of the shafts are held in bearings in housings located in the top wall of the frame portion and pinion gears are housed within the frame portion below the housings. The bearing housings are each formed by two separable portions that hold a bearing between them. The upper housing portion has a deformable relatively thin cover that visibly deforms if the bearing breaks and the separable portions contain any broken parts. A further, lower bearing can be held by the bottom wall of the frame portion. Fastening means such as bolts on a surrounding ring secure the housings in place.
