A friend and I are starting our first lawn service comany and we need to choose a mower. I have been looking at Husqvana, Gravley and Exmark walk-behinds. I think a 36 inch will suit us best for our first one. We plan on cutting 30-50 lawns per month in Florida (St Augustine grass). I am unsure about floating or fixed, hydrostatic or not. We will probably want a sulky so want to know recommended HP. The last thing is that we would like the best price for our basic needs. Thanks!!!
