What size excavator or skid steer do I need for a hydraulic auger drive?
The right machine size depends on three main factors: hydraulic flow, operating weight, and the hole size or ground condition you need to drill. A compact excavator or skid steer can handle smaller diameter holes in normal soil, while larger machines are better for bigger augers, deeper drilling, and harder ground. In practice, the hydraulic system matters as much as machine weight because the auger drive needs enough oil flow for speed and enough pressure for torque. You also need a stable carrier and a mount suited to the machine geometry. If the drive is too small, drilling is slow; too large, and you may waste hydraulic capacity or overload the setup. VANROCK manufactures and supplies auger drives for a wide range of excavators and skid steers and can recommend a suitable drive, bracket, and auger size based on your carrier specs and target hole diameter.
