Description
The Kato AS-12 is a compact, rubber-tire skid steer loader engineered for serious productivity in confined spaces. Powered by a 21 HP Yanmar 3TNV76 diesel engine, the AS-12 delivers genuine performance where larger machines simply can't go — urban job sites, interior demolition, landscaping, and agricultural applications.
With pilot-operated joystick controls, an SAE-rated operating load of 728 lbs, and a bucket breakout force of 1,658 lbs, this machine punches well above its weight class. Built on a rubber-tire chassis with a maximum travel speed of 4.35 mph, the AS-12 is as agile as it is capable.
What sets the AS-12 apart is its no-nonsense, straightforward design — no complex systems to learn, no steep operator learning curve. Any experienced equipment operator can step in and be productive from the first hour. And when you need parts, Kato CES stocks them in the U.S. so you're not waiting weeks for overseas orders. Less downtime. More work done.

Why Kato CES?
Kato Works has been manufacturing equipment in Japan since 1895. Kato CES (Compact Excavator Sales) has been the North American distributor of Kato compact equipment for over 30 years — family-owned and operated, with a reputation built on expertise, integrity, and unparalleled customer service. The AS-12 is Japanese-built equipment, U.S.-distributed and supported through a nationwide dealer network.
The AS-12 is intentionally simple — built to work, not to impress a spec sheet. That simplicity means any operator can get productive fast, and it means fewer things to go wrong. When something does need attention, Kato CES stocks parts in the U.S. so your machine is back up quickly. No waiting on overseas shipments. No excuses.
Where other skid steers sacrifice maneuverability for raw capacity, the Kato AS-12 excels in the spaces larger machines leave behind — and it keeps working long after the sale with real dealer support behind it.
