Retractable Undercarriage for Enhanced Stability
The AHM AX-16S 23 HP B&S gasoline mini excavator features a retractable undercarriage that adjusts from 3'3" to 3'11" for enhanced stability and performance. This provides better balance when handling heavier loads and allows for more efficient digging and lifting. With a 71-inch digging depth, 114-inch max digging radius, and a compact width for easy maneuvering, it excels in tight spaces. It lifts up to 265 lb and minimizes site disruption with its reduced tail-swing. The retractable undercarriage also makes it ideal for accessing confined job sites.

Double Enhanced Power and Improved Efficiency
Briggs & Stratton Efficient Engine
Equipped with a Briggs & Stratton Dual Cylinder 3864 engine, this compact powerhouse packs advanced technologies, delivering exceptional power and efficiency while being lighter than competitors. Boasting 70% more horsepower and 50% larger displacement than 13.5hp 420cc models, it ensures superior performance.
- V-Twin OHV Technology: Offers better balance, increased power, and optimized performance for longer life and improved fuel economy.
- Robust Construction: Features cast iron sleeve, balanced crankshaft, and full-pressure lubrication, ensuring longevity and wear resistance.

71 in. MAXIMUM DIGGING depth
26% Increase in Digging Force
- Experience top performance with the AX-16S, featuring a 71-inch max digging depth and 3260 lbf of digging force. Whether tackling tough clay, rock, or compacted soil, its advanced boom design ensures smooth and efficient operation.
- With a max digging radius of 114.2 inches and a max dumping height of 59.3 inches, the AX-16S is built to handle demanding tasks with ease.

Precise Hydraulic Pilot Control System
- The precise hydraulic pilot control system outperforms cheap mechanical controls. When you stop the joystick, the machine responds immediately with smooth, precise action. Unlike the delay in traditional mechanical systems, pilot control ensures smoother, safer operation while reducing wear and extending the machine’s lifespan.
- In addition, the hydraulic pilot lock switch adds an extra layer of protection, preventing accidental machine movement by locking the hydraulic system when idle, ensuring safety during transport or while not in use.

Adjustable Undercarriage
With a retractable width ranging from 37 to 47.2 in., this innovative system transforms your excavator's capabilities in multiple ways. Narrow the tracks to access confined spaces where standard machines can't operate, then expand them for maximum stability on challenging terrain. This versatility eliminates the need for multiple specialized machines while enhancing safety by preventing tipping hazards.

Compact Design
With a total width of just 3'3", our excavator is easy to maneuver in tight urban and residential spaces. The reduced tailswing model minimizes the risk of property damage near buildings and obstacles due to its minimal swing radius.

Easy Maintenance
On this heavy-duty compact excavator, maintenance is quick and easy. Located conveniently at the rear, accessible maintenance ports allow effortless removal of guards and straightforward servicing of key components. These accessible points minimize downtime, ensuring your machine operates at peak performance consistently.

Adjustable Dozer Blade
Our 1000mm wide blade stands out from competitors, offering superior coverage. It adjusts from -16cm to +16cm in height, ensuring versatility across different terrains. Features like Dig-to-Blade and dozer float make clean-up effortless.

Ready-to-Use Hydraulic System
- Our small excavator arrives with hydraulic oil pre-filled for immediate use. Monitor oil levels and temperature effortlessly with the built-in meter, ensuring you have full control over the machine's status at all times.
- Adding hydraulic oil is easy with the conveniently located next to the right-side excavator control lever. Clear labeling on the machine body ensures seamless operation.

Compatible with Multiple Attachments
- Equipped with enhanced hydraulics, our compact crawler excavator effortlessly accommodates high-flow attachments like auger, hydraulic thumb, and hydraulic breaker hammer(not incl.).
- From effortlessly demolishing tough materials to achieving precision in drilling tasks and securely handling debris, our tools excel in diverse environments.

Enhanced Durability
The improved track frame design reduces mud buildup and minimizes wear on the carrier rollers, enhancing the machine's durability. Forged structure at key boom joints, with optimized shape and thickness, alleviates stress and boosts longevity.

Top-Quality Workmanship
The machine's structural components are crafted by Japan Komatsu's trusted manufacturers. The entire vehicle undergoes shot blasting, pickling, phosphating, and spraying processes, enhancing paint adhesion for increased durability, resistance to fading, and a smoother finish.

Fantastic excavator! Far exceeded my expectations in power and quality. Not a loose bolt not a scratch in the paint. The expanding track base is worth the trade off for not being able to get the Kubota motor but the Vanguard 23hp is awesome power. I have yet to run it above 1/4 throttle for heavy digging in dry fairly hard clay and it’s quieter than my Kubota tractor. It seems very reasonable on fuel too. I drove it out of the crate onto the box truck lift gate.
Good seller & value. I ordered a narrow bucket and ripper from them. Both were in the hands of FedEx within two business days and delivered quickly. Shipping won’t necessarily be from CA but most likely originate closer to you. I live in the northeast and mine came from NJ for faster delivery. As for the mini excavator, the retractable undercarriage was the big selling point for me. It gives the machine way more stability, especially when digging into heavy stuff. You can extend the tracks for more balance and support, which makes it easier to handle those bigger, tougher jobs. It feels solid, and I’ve been able to dig deeper and lift heavier loads without worrying about tipping over. The controls took a bit to get used to, but it’s been smooth since then. It’s a bit slower to move around, but that’s not a big deal when you’re working on tough, uneven ground. Overall, the machine’s been exactly what I needed and more.
