Anyone familiar with the John Deere F525? I'm looking at used mowers. I saw some F series machines with front mount mower on E-bay. The F525 has a unitized engine/pump(?) w/Kawasaki engine. I like the idea that the deck is offset which would help when mowing around bushes and smaller trees. We have a good JD dealer in our area but he doesn't have much in used equipment. Any experience with the F525, F710, or F725? I don't know what is different about the F710 but they have similar engine/deck size as 525, dual rear wheels and higher resale value(?). Any comments would be appreciated.
