Mike, the mower I assume is side discharge. This assumption is based upon the NH literature that states that the only rear discharge mower is 72" and he quoted a price for a 60".
I did briefly talk to him about a rear mount finish mower (for the reasons you mentioned). My concern was the posibility (or, in my case, likelihood) that I might do some damage to my fence or the mower as I learn how to negotiate the tractor around my house. As the dealer is a neighbor of mine, he knows the conditions under which the tractor will be used. His statement was that a rear mower would be inappropriate for my use. For the reasons mentioned above, his opinion supported my concerns.
Thanks for the reply.
