You out there might think this part of the combine looks mighty dirty. The boys on the farm here never pressure wash around bearings. Th reason is that pressure washing puts water in the bearings and causes bearing failure. Tha is a bad thing to happen if you have another 400 acres to go.
Heck, if I had been on the farm and using a pressure washer, I would have blasted that dirt right off! It's a good thingk you provided this lesson in farm mechanics. Congratulations on being able to upload.
