Recently I have been concentrating my flyers and mailers into more affluent area's and most of the lawns are aporx 1-5 acres. Now my questions is.. do I go for a large walk behind? or a ZTR? .. my only personal reason for going with a walk behind with a velke would be from what i have hear the ztr's are better for commercial use because of the weight. and in a more affluent area I do not want to be making any major tire tracks... is there any one else in this situation? or any recomendations? I could use a large mower or ztr on a couple of my current properties .. 90% of mine are between half- 3/4 acre lots. but if i get this contracts for next season i need something bigger than a 36 inch.. thanks for any help. also i would like to stay with an exmark..
