All specifications on this page were taken directly from Cub Cadet, the manufacturer. Figures from Cub Cadet Ultima Series ZT product comparison (specifications) and Cub Cadet series page, checked November 2, 2026: Cub Cadet Ultima Series ZT product comparison (specifications), Cub Cadet series page. Columns are deck sizes. The 54-inch column covers ZT1 54 (Kohler) and ZT1 54P (Kawasaki, front caster suspension).

One deck build, five widths

Each ZT1 shares a fabricated deck of 11-gauge steel, a Hydro-Gear EZT 2200 and a 7 mph top speed. Reverse is 3.5 mph. They'll all cut from 1 to 4.5 inches, carry 3.5 gallons of fuel and seat you on a 20-inch high back. What's different as you go up is the engine, the blade count and the rear tires.

The 42 and 46 run a 21.5 hp Kawasaki FR 651V and two blades. The 50's got a 23 hp Kawasaki 691V and three blades. At 54 you've got two picks. The ZT1 54 has a 24 hp Kohler 7000 KT724. The ZT1 54P has the 23 hp Kawasaki, front caster suspension and 20x12 rear tires. The 60 runs a 26 hp Kohler 7000 KT726.

Rear tires are 20x8-8 on the 42 and 46 and 20x10-8 on the 50, the ZT1 54 and the 60. Front tires are 11x6-5 on all five. Got tight spots between trees? A 42 or 46 gets you in there. If your place is mostly open, a wider deck saves you passes.

ZT or Z?

The two lap-bar Ultima lines overlap from 42 to 54 inches. The ZT is the one that goes to 60, and it's the one with Kohler engines. The Z gives you a cut-and-sew seat with a head bolster, and the Z3 50 adds a reinforced deck. Compare the seats before you choose, since you'll spend hours in one.

A 60-inch deck makes sense on open ground from a couple of acres on up. Zero-turn demand runs highest with us from March through July. If you want one mowing by spring, don't wait for the first green-up to start looking.

Questions people ask

Which Cub Cadet Ultima ZT1 has a Kohler engine?

Two of them. The ZT1 54 runs a 24 hp Kohler 7000 Series KT724, and the ZT1 60 runs a 26 hp KT726. Both are 747 cc. The 42, 46, 50 and the 54P use Kawasaki FR engines from 21.5 to 23 hp. If you've got a Kohler preference, that narrows it to those two.

How is the Cub Cadet Ultima ZT1 54P different from the ZT1 54?

The 54P swaps the Kohler for a 23 hp Kawasaki FR 691V. It adds front caster suspension and rides on 20x12 rear tires, where the ZT1 54 has 20x10. The deck, the transmission and the 7 mph top speed don't change. You get the same 20-inch high-back seat on both.

What cutting heights does the Cub Cadet Ultima ZT offer?

From 1 to 4.5 inches, on each deck size from 42 to 60. The 42 and 46 use two blades, and the 50, 54 and 60 use three. All five decks are fabricated from 11-gauge steel. They're driven by the same Hydro-Gear EZT 2200, so you'll mow at up to 7 mph on any of them.

How much does a Cub Cadet Ultima Series ZT mower cost?
