All specifications on this page were taken directly from Cub Cadet, the manufacturer. Figures from Cub Cadet Ultima Series ZTXS product comparison (specifications) and Cub Cadet series page, checked November 2, 2026: Cub Cadet Ultima Series ZTXS product comparison (specifications), Cub Cadet series page. ZTXS models steer with a steering wheel (Synchro-Steer). Columns are deck sizes; ZTXS4, ZTXS5 and ZTXS6 are named in parentheses where they differ.
Built like a ZTX, steered with a wheel
Cub Cadet calls the steering Synchro-Steer. You turn a wheel, and the mower still makes a zero-turn's tight turns. Under you, it's built much like the lap-bar ZTX. One difference is the 48-inch deck. On the ZTXS, it carries the same 2-gauge reinforcement as the 54 and 60.
The tank holds 5.5 gallons, so you'll stop less often on a big mow. Cutting height runs from 1 to 4.75 inches, with three blades on each deck. Front tires are 13x6.5-6, and reverse tops out at 3.5 mph. Rear tires are 22x12-12 on the 48 and the ZTXS4, and 23x12-12 on the ZTXS5.
Which trim, which deck
The ZTXS4 runs a Kohler Pro 7000. That's 24 hp on the 48 and 26 hp on the 54 and 60. It uses a Hydro-Gear ZT 3100 and tops out at 8 mph. The ZTXS5 comes in 54 and 60. It's got a 24 hp Kawasaki FS 730R, a Hydro-Gear ZT 3200 and 8.5 mph.
The ZTXS6 is offered as a 60. It runs a 25.5 hp Kawasaki FX 801V of 852 cc and a Hydro-Gear ZT 3400 Charged, good for 9 mph. Its rear tires are 24x12-12, and the seat's a 24-inch high back. Prefer lap bars? The ZTX covers the same three deck widths.
Torn between the ZTXS4 and ZTXS5? Look at the engine you'd rather own and the speed you'll use. The ZTXS4's Kohler makes 26 hp on the 54 and 60, against the ZTXS5's 24. The ZTXS5 is rated at 8.5 mph and gets the 24-inch seat.
