- +11-gauge AeroForce fabricated deck with a well-regarded, even cut
- +Limited lifetime warranty on the frame and fabricated deck shell
- +SmartJet deck wash port built in
Worth knowing

- −Polymer seat suspension only; no true suspended seat
- −Cub Cadet quotes up to 4 acres, which is optimistic for a 50-inch deck
Our verdict
Cub Cadet Ultima ZT1 50
The value pick of this group, and it is not close. You get a Kawasaki FR691V, a fabricated 11-gauge deck and a lifetime frame warranty for less than most rivals charge for a lesser engine. The recurring owner gripe — grass building up on top of the deck — is real and annoying, but it is a cleaning chore, not a design flaw that will cost you the machine.
