Kubota Mini Excavators (KX91-3S2/U20-5 Series)
Eco-Efficiency: Equipped with OEM liquid-cooled diesel engines (14.5-47.8kW), fuel consumption ≤242g/kW·h. Multi-power modes reduce overall consumption by 15%, ideal for extended earthwork.
Precision Operations: Ultra-tight turning radius (front min. 2410mm) enhances maneuverability in confined spaces. Digging depth 4290-5245mm, optional 0.04-0.35m³ buckets suit herb harvesting and pipeline laying.
Robust Performance: Hydraulic-optimized digging force >65.2kN + dozer blade for leveling. Rubber tracks (ground pressure ≤33kPa) prevent surface damage in orchards/wetlands.
Ergonomic Control: Suspension seat + 3D AC system in cab. 7-inch LCD with rearview imaging and 300% brighter LED lights. Hydraulic pilot control reduces effort by 30%.
Enduring Reliability: Heavy-duty chassis + steel/rubber tracks. Core components machined by 5-axis systems (±0.01mm precision). Multi-stage hydraulic filtration (NAS Class 8 cleanliness). warranty on critical parts.
