Handles my hilly 3 acres with ease

I was worried about my slope but the Z2 stays planted and the Kawasaki has plenty of torque. AeroForce deck leaves a picture-perfect stripe.

The seat alone is worth the upgrade

Coming from an older tractor, the 20-in high-back seat is a game changer. Two hours in and I'm not sore at all. Cuts fast and clean.

Feels like a commercial machine

Solid steel frame, fabricated deck, real Kawasaki power. Cub Cadet nailed the fit and finish on this one.

Great mower, slight learning curve

First zero-turn and it took a lawn to get comfortable with the lap bars. Now I wouldn't go back. Wish the striping kit was included.

Cuts my 4 acres in under an hour

The 54-in AeroForce deck plus the 726cc Kawasaki is the perfect combo. Full-speed cuts on my Bermuda and no scalping on the humps. Dealer had it delivered in five days and it started on the first key turn.

Feels like a $6k mower for the price

Compared this side-by-side with two other brands at the dealer — the Cub Cadet had the thickest frame, the best-feeling seat, and the smoothest hydros. Zero regrets after a full season.
