Komatsu PC78UU-6 Mini excavators

The pre-owned 2001 Komatsu PC78UU-6 mini excavator is designed for contractors who need strong performance and precision in confined urban or residential spaces. Built in Japan, it runs on a 54 hp Komatsu S4D95LE-3 diesel engine and weighs 7,700 kg, combining compact mobility with dependable digging power.
