Quest X-Series
Looking for a residential zero-turn mower with commercial features and performance? You’ve found it in the new Quest X-Series. The powerful Kohler engine, upgraded 48-inch UltraCut Series 3 cutting deck and heavy-duty Hydro-Gear transmission enable Quest X-Series to cut at up to 8 mph. When combined with the incredible maneuverability of the low center of gravity frame design and the smooth rolling of the large drive and caster tires, Quest X-Series offers an unbeatable combination of performance and value.
A new armrest-equipped operator seat provides a smooth ride over bumpy lawns, while a deeper floor pan offers increased legroom for the operator. A standard deck step is included to ease mounting and dismounting the machine, while an integrated hitch and tools-free belt shields ease access for service and maintenance. However, with just two annual grease points and low-maintenance integrated hydro transmissions, servicing the Quest X-Series isn’t something you’ll need to do often. That’s more time for you to do the things you love.
If you’re looking for even more power and performance, check out our Radius line of zero-turn riding mowers.
Note: This is a new product and will not be available in dealerships until Spring 2023.

Micro-Mulch System
The aerodynamically designed deck, baffles and blades create airflow patterns that circulate leaves and grass for repeated cuttings and even dispersal deep into the turf. Mulching baffles also keep the underside clean, which reduces grass buildup and clumping.
