The respective Scag and Gravely dealers in my area have quoted me the same price (3,000) for both the Scag and Gravely machines equipped as follows: gear (belt) drive, 15 hp Kawasaki, and 48" fixed deck. The Scag dealer was not sure if his machine was powered by a single or a twin Kawi--I'm pretty sure it's a twin . He has to order the mower, as he is a small mom-and-pop operation, stocking only the "big sellers": while he didn't have any walk behinds on the floor, he did have three Tiger Cubs ready to go. Hmmmmm. . . . The Gravely dealer was an entirely different experience. They had nearly the entire line assembled and on the floor, were helpful in the extreme, gave me a catalog, and quoted me prices that were below MSRP. Obviously, the Gravely dealership wins that part of the contest hands-down. They also had a 13 hp Kawi twin wb w/ 36" fixed deck for 2,500. Is there going to be a noticeable (read that regrettable down the road) difference between the 13 and 15 hp? The dealer tells me that the 13 will have no problems whatsoever pulling a Velke. In fact, he claims a mower with an 8hp engine would do the job, but I am not so sure. The 36" deck poses no problem, as I can use it where the 48 won't fit. The only reason I hesitate on the Gravely is I've seen several posts about belt wear/fraying issues. Thanks for the help!
