Just wondering if the suspension is enough reason to buy one. Who can tell me how they compare to a rigid frame with a suspension seat? Will be for residential 3 acre but not the smoothest lot out there. (new home seeded a month ago) Local dealer has a 1500 with the 28 vanguard, I like the feel of the Huslter Z much better but can't get past the suspension on the Ferris. thanks Also Big Dog mowers, any comments?
