Looking for a residential mower for 2.5 acres. Have been looking at Bobcat Fastcat, Scag Freedom Z, Bad Boy CZT, Hustler Fastrak, etc. I've also looked at the Ferris IS 1500Z, but unfortunately, the Ferris website is lacking detailed specs. In addition, the Ferris is being quoted at $7800 when all the others are coming in around the $5600 range. Outside of the suspension, what else would make the Ferris have a $2000 premium over the others? I want to be sure I'm comparing apples to apples, but I'm beginning to think the Ferris is an orange. Thanks.
