Auger Drives

Standard, high speed and horizontal auger drives built for reliable rotational power across 0.5-52 ton excavators.

Section 1

Standard Auger Drive

The HMA series hydraulic auger drive couples a hydraulic motor with a planetary gearbox for powerful, reliable rotational drilling. Ten models cover 0.5-52 ton excavators with torque from 1,900 N·m up to 100,000 N·m, suited to piling, fence, pole, well and foundation drilling.

Drives accept round, hex or square shanks (configurable per machine) and are matched to the full range of HMA hitches and auger flights for complete, dependable drilling systems.

Ten models, 1,900-100,000 N·m
0.5-52 ton excavator range
Hydraulic motor + planetary gearbox
Round / hex / square shank
Configurable hose and shaft
