Product Description
Built for immediate deployment on tight jobsites, this 2021 Doosan DX75-9C mini excavator delivers 7-ton performance where larger machines can't reach. Powered by a Yanmar 4TNV98-EXS engine producing 39 kW at 2200 rpm, this compact workhorse handles trenching, grading, and foundation work with precision. The 0.3 m³ backhoe bucket generates 53.4 kN of digging force, reaching 4,080 mm deep and extending 6,115 mm horizontally for maximum site coverage.
Measuring just 2,180 mm wide in transport configuration, this excavator navigates confined construction zones while maintaining stability through its 34 kPa ground pressure. The variable piston hydraulic system ensures responsive control during loading cycles, demolition tasks, and utility installations. With a 111-liter fuel tank and 90-liter hydraulic reservoir, expect extended runtime between refills.
