Product Overview
The TGEC excavator hydraulic auger drive turns your excavator into a serious earth-drilling machine. It replaces the bucket on the boom, ties into the auxiliary hydraulic circuit, and uses a hydraulic motor with gear reduction to deliver high torque at low speed. The output shaft spins the auger bit, boring clean, round holes in soil, clay, and mixed ground. Part of the TGEC excavator auger lineup, this drive is built for fence posts, sign posts, footings, tree planting, and utility pole installation. Fourteen sizes cover 1.5 to 30 ton excavators with torque from 2510 to 39500 Nm, and each model works with a variety of auger bits, extensions, and adapters. For help picking the right drive and bit combo, check out our auger selection guide.

Excavator Compatibility Guidance
TGEC auger drives cover excavators from 1.5 to 30 tons. Each model has specific hydraulic flow and pressure requirements, and the excavator needs an auxiliary circuit to power the drive motor. The TG-EG2000 requires 40 to 75 L/min at 80 to 170 bar, while the TG-EG30000 requires 100 to 150 L/min at 100 to 170 bar. Drive weight ranges from 55 kg to 485 kg, so mini excavator operators should confirm the machine can handle the drive weight plus drilling load at working reach. Custom mounting brackets are supplied for your specific excavator make, model, and pin dimensions.
Typical Applications
Fence and post installation: Drill consistent round holes for wood, metal and vinyl fence posts, sign posts and guardrail posts.
Footings and foundations: Drill pier holes for deck footings, building foundations, pole barns and structural supports.
Tree planting and landscaping: Drill holes for tree and shrub planting in compacted soil or large-scale landscaping projects.
Utility and municipal work: Drill holes for utility poles, street light bases and traffic signal foundations.
Agricultural installation: Drill post holes for farm fencing, livestock enclosures and pole barns.

Working Principle
Pressurized hydraulic fluid from the excavator's auxiliary circuit drives the motor shaft, which feeds into a gear reduction set that drops speed and multiplies torque. The output shaft transfers that torque to the auger bit, where cutting teeth bore into the ground and spiral flights carry spoils up and out of the hole. The excavator boom provides down-pressure and lift while the operator regulates hydraulic flow to control drilling speed. High-torque, low-speed output is essential—too much speed without enough torque just spins the bit in place without penetrating, especially in compacted or clay soil.
