KATO 55N4 MINI EXCAVATOR

UNRIVALED POWER, STABILITY & PRODUCTIVITY

The KATO 55N4 Mini Excavator delivers exceptional digging performance, rock-solid stability, and legendary durability in a compact machine built for demanding jobsites. Designed to outperform others in its class, the 55N4 is often more productive than a loader-backhoe in limited access areas, making it ideal for construction, utilities, landscaping, and year-round operation.

Powered by a 54.7 HP Yanmar Tier 4 Final diesel engine, this mini excavator provides strong breakout force, smooth hydraulic response, and efficient fuel usage. Hydraulic pilot joystick controls with armrests deliver precise, fatigue-reducing operation, while auxiliary hydraulics and variable displacement piston pumps ensure excellent attachment performance.

Operators stay comfortable in all seasons with a standard heated, ROPS-certified cab, or a 4-post canopy option for open-air operation. With rubber or steel track options, a standard backfill blade, and fast travel speeds, the 55N4 is built to work harder, longer, and more efficiently.
