Product Description
Built for serious work at a fraction of new-unit cost, this 2020 Hitachi ZX70-5G mini excavator delivers proven Japanese engineering from its Sichuan, China base — ready for immediate deployment. Powered by a Yanmar 4TNV98-AVHBW 4-cylinder water-cooled engine producing 42.4 kW at 2,100 rpm, it handles demanding dig cycles without compromise.
At 6,700 kg working weight with a 0.33 m³ backhoe bucket, this 7-ton machine punches well above its class. A bucket digging force of 55 kN, maximum digging depth of 4,170 mm, and 70% grading capability make it a reliable performer across construction, utility, and land-clearing applications.
