Ultima ZT1 (series) review
Our take on the Cub Cadet Ultima ZT1 series
The Cub Cadet Ultima ZT1 is the entry level of the Ultima ZT zero-turn line. Every ZT1 has a Kawasaki V-twin, dual hydrostatic drive and a fabricated AeroForce deck. The line comes in several deck sizes. This page covers the series as a whole. Our model reviews cover the ZT1 42 and ZT1 50 in detail.
What every ZT1 shares
All ZT1 mowers use a continuous 2 by 2 inch tubular steel frame with an e-coated lower section. Drive is a pair of hydrostatic transmissions. Top speed is 7 mph forward and 3.5 mph in reverse. The deck is fabricated from 11-gauge steel and has 15 cutting positions. A foot pedal with a dial sets the height.
The seat is a 20-inch high-back design with a knob adjustment. A rear tow hitch is included. The fuel tank holds 3.5 gallons. Tires are 11×6-5 casters in front. The rear tires depend on the deck size.
Which ZT1 size fits?
The 42-inch model has a 21.5 hp Kawasaki and a two-blade deck. It suits smaller yards and tighter gates. The 50-inch model has a 23 hp Kawasaki FR691V and a three-blade deck. It suits larger lawns. A 54-inch model also exists with 24 hp. Pick the widest deck that still fits your gates.
Warranty
Cub Cadet backs the ZT1 with a 3-year, no-hour-limit warranty. The frame and fabricated deck shell carry limited lifetime coverage.
Limits to know about
The ZT1 uses lap bars, not a steering wheel. The transmissions are sealed on some models. It is a step below the ZT2 and ZT3 in comfort and power. It is built for residential use only.
Who should buy it
Buy a ZT1 if you want a fabricated deck and a Kawasaki engine at an entry price. Step up to the ZT2 for more refinement.
