I am ready to buy my first mower(s). I have 20 accounts thus far.All residential. 75 % of them are 5000 sq ft or under (condos and townhomes) and none are bigger than 10,000. I have a budget of $3000 for a walk behind and am considering the 21 in commercial Lawnboy as my trim mower ( 2 stroke model local dealer has 2 left at $699.00.) So I've narrowed it down to either a 36in belt drive and 21 in trim, A 32 in single hydro(snapper or ferris) and 21 in trim or the quick 36 single hydro and trim....or suck it up this season upgrade to honda hrc or toro and get a larger hydro as new accounts are obtained. Thanks for your help, you guys must get tired of answering this question.
