Ultima ZT1 50 in. Zero Turn Riding Mower — 25 HP Kohler V-Twin
The Ultima ZT1 50 in. zero turn mower pairs a Kohler 7000 Series V-twin OHV engine producing 25 HP with a fully fabricated AeroForce deck, delivering high-performance cutting with exceptionally smooth, quiet operation.
Its standout feature is Synchro-Steer technology, which coordinates all four wheels for genuine one-handed operation and confident handling on slopes up to 20 degrees — a meaningful safety and control advantage over conventional zero-turns on hilly ground.
