Ok heres the deal. I bought a 36" wb Emxark gear drive 4 months ago thinking I'd start a lawn service. Well it appears this could actually work. I've went from 0-6 accounts without even trying. The problem is now I'm thinking after reading all the posts I could be more effecient with a hydro 48". Should I upgrade already? I stopped at the Exmark dealer to check out a hydro ,and the TTHP 48" is awesome. I can trade up for another $2850 out the door. What do you think? So far my accounts are 7-15k yards ,but with a 48" hydro could I do more?
