G.Williams, I have already started doing this myself.
For some reason the shouldn't let non machanicly incliend people get in this biz.
I have a few that come to me after hours to fix their equipment, fortunaly I have many parts in stock. Mostly for my own back up parts, but they use them more than I.
Here we have close to 1000 or so just in the lawn care section, and very few have a machanic.
