I am looking into starting a mowing residential business but have a medical concern first. I have a disc in my back that is going bad,no pain yet and I can move around fine so far. My concern is would I do ok mowing or would this be to much for me and start problems I don't have now. Had some people say I would do just fine while others said this would be to much bending and being hunched over to much.Doctor wasn't sure so thought I would ask. Friend of mine suggested power washing for reasons of can pick when I want to work and less money if I find out I can't do this. What are your thoughts?
