Would like a little help with a mower decision. I am buying a 36" walk behind, belt drive. Interested in the Ferris which has a 15 hp motor and an exmark that has 12.5 hp. I guess my question is relly in regards to the machine. They look almost the same, except for the engine size. My company is strictly residential and we use 21" and 32" mowers for everything. Been at this for five years full time but never had to buy anything larger than the 32". Just got a new client (condo assoc.) and thought the 36" would make more since. I appreciate any help and I enjoy reading all the good info.
