Anybody using the Perma-Green ride-on sprayer speader? We are using lesco power spreaders now and thinking of a change but need some feed back from someone who may already be using them. How much higher is the maintaince (7-9 actual hours per day run time). How small of a lawn is to small for this speader? Most of our account are from 3,000-30,000 sq. ft.. Any other info would be greatly appreciated. Thanks M.
