Earlier this week I dropped my 820 off at Ag Power Enterprises to get the fuel filters changed. On those old tractors you have to "bleed" the air out of the fuel lines to get them started again. The point is you have to know what you are doing so I thought let the professionals take care of it. It would be tough if the tractor stopped during a parade! In the picture is a 4440 that Bill was working on. It apparently got stuck in a wet spot in the field and stripped the hub on the axel. In addition it also broke the cast iron wheel. Those type of things happen when equipment gets abused in the mud! At some point all farmers have had these type of things happen to them.
