I looked at the used Lawnaire 28 today. It seems to be in very good conditions. All the bearings are tights and everything seems to rotate very smoothly. You can tell the units has been taken care of or not used very much. The belts are a little dry rotted. How much work is it to change the belts? It looks like a nightmare job. What do the belts cost. I probably would change them all before using. I would hate to get a bunch of jobs lined up and have a belt brake.
