Eterra Auger Drive for Skid Steer

Eterra Auger Drive for Skid Steer

The Eterra auger drive for skid steer is a heavy-duty post hole digger built for fence lines, deck footings, tree planting, sign posts and utility work. Three models — 2500, 3500 and 4500 — deliver 2,100 to 3,350 ft-lbs of torque across a 7 to 30 GPM range, so you match the drive to your machine instead of forcing your machine to match the drive. Every unit ships from Skid Steer Store with a 2" hex output shaft and hydraulic hoses and couplers included.

Why Operators Choose the Eterra Auger Drive

• Planetary drive system — engineered to prevent the shaft pullout failures common to lower-cost auger drives.
• Reinforced gearbox and oversized thrust plate — locks the output shaft in place and spreads load evenly.
• 2" hex output standard — adapters available for round or larger hex bits, so existing tooling still works.
• Optional Flip Mount frame — 180° rotation for tight spaces and angled drilling.
• Locking collar — keeps the auger from swinging during transport.
• Compact 140 lb frame — preserves your loader's rated operating capacity.

Model Comparison

Choose the model whose flow range brackets your machine's auxiliary output. Running below the minimum costs speed; running above the maximum shortens motor life.

Frequently Asked Questions

What hydraulic flow do I need?
7 to 30 GPM depending on model. The 2500 runs on 7–17 GPM, the 3500 on 10–25 GPM, and the 4500 on 13–30 GPM.

What size bit will it turn?
Up to 30" on the 2500 and up to 36" on the 3500 and 4500, subject to soil conditions.

Will it fit my skid steer?
It ships with a universal skid steer quick-attach plate fitting the vast majority of skid steers and CTLs. A Bobcat MT mount is available. Contact Skid Steer Store with your make and model if unsure.

Standard Mount or Flip Mount?
The Flip Mount rotates 180 degrees, letting you invert the auger for tight spaces and angled drilling without removing the attachment.

Can I use my existing bits?
Yes. The 2" hex output plus Eterra adapters convert to 2" round or 2-9/16" round to fit most other manufacturers' bits.
