The plan now is a brand new Ferris 52" IS2000 with KAW FX801V, its overkill for my application but I like that.
If a lower level model had the independent front suspension I would go that route, but the IS2000 is the lowest model with this feature. I wish Ferris implemented independent front suspension on all their models.
I expect to pickup the ZT mower in a week, so I have until then to make any changes.
I appreciate the comments.
