Does anyone have any experience with this model mower. I was considering this model as opposed to the 757. The mower is centered on the 757 which makes trimming work a bit more challenging. I love how the mower is offset to the left on my F525 as this makes trimming a snap. With the mower in front, it is real easy to get up under trees, etc. The mower also flips up for cleaning as does the power train deck. I am not too keen on the aircooled Kohler engine but they are simpler to maintain. The Kawisaki 17 hp in my F525 is aircooled and has been a real good engine (monster torque) Would appreciate any comments, opinions, feedback, and suggestions. Thanks.
