Bob, I have an F-525 and they are VERY manuerverable with respect to getting into tight spots. John Deere is going to discontinue production of them this year I understand. They are not very good with respect to traction on slopes and prone to tire spine unless you learn how to shift you butt cheeks from side to side of the mower to shift weight and traction to the light wheel. I purchased mine used but in great condition. I had been using a Cub 154 Lo Boy to cut the grass and it took about 4 hours. The F-525 cut that in half. If the money spent is not an issue and you want a front mower, I would suggest the F-687. Over all best recommendation would be the 777. EXCELLENT traction, hp, manueverability but not so much in tight spaces with the 72 inch mower and better with the 60 inch mower. You can't beat those Kawaski engines. As far as lawn cutting, the F-525 cuts circles around my 4410 and the offset front mower makes tight trimming work a pleasure and really cuts down on string trimming.
