Description
The Kato HD55N4 is a rugged, hard-working mini excavator that outperforms any other machine in its class — and is more productive than a loader-backhoe when working in limited-access areas. With a 63.8 HP water-cooled diesel engine, 12’8″ digging depth, and a 11,071 lb bucket breakout force, the HD55N4 brings full-size excavator capability in a compact, job-site-ready package.
Operator comfort and simplicity are built in from the start. Short-lever hydraulic pilot controls with armrests deliver a high degree of operational responsiveness, and any experienced operator can step in and get to work without a steep learning curve. Standard heated cabin or optional 4-post canopy means year-round productivity. And with Kato CES U.S.-stocked parts behind it, you stay on the job when it counts.
