Auger Torque 20000 MAX Earth Drill for 13–20 Tonne Excavators

The Auger Torque 20000 MAX earth drill is a hydraulic auger drive for 13–20 tonne excavators. It turns an auger with up to 19,564Nm of torque to drill post holes, tree pits and foundation holes from 150mm to 1,000mm across.

It runs on 80–170 l/min of oil at 160–240 bar from your excavator's auxiliary circuit, and its 75mm square output shaft takes Auger Torque S6 augers. It's supplied with hydraulic hoses. Quick couplers aren't included, and Auger Torque recommends plumbing it in directly for the best flow.

What You Need to Start Drilling

The earth drill is the hydraulic drive unit that turns the auger. To start drilling you'll also need:

• A hitch to mount it on your excavator: the 20000–25000 MAX hitch, made to fit your machine's pins and dipper.
• An auger: the S6 auger in the diameter you need, up to 1,000mm with this drive.

Key Features

• Up to 19,564Nm of torque at 240 bar
• Recommended for 13–20 tonne excavators
• Drills holes from 150mm to 1,000mm across with S6 augers
• 75mm square output shaft
• Epicyclic (planetary) gearbox to multiply the motor's torque
• High-quality hydraulic motor
• Non-dislodgement shaft: a one-piece shaft that can't drop out of the drive
• Output shaft bearings that Auger Torque says are up to 50% larger than competing drives'
• Forged hood ears for extra strength where the hood takes the most strain
• Supplied with hydraulic hoses (quick couplers not included)
• Optional 2-way valve to run it from a single-acting hammer circuit, and an optional pressure relief valve to protect the motor

Where It Works Best

• Pile holes and foundations
• Large tree planting
• Lighting columns, gantries and large posts
• Civil engineering and groundworks

Hydraulic Requirements

The 20000 MAX needs a two-way auxiliary circuit that can supply 80–170 l/min at up to 240 bar. Oil flow sets how fast the auger turns and pressure sets the torque, so a machine at the low end of the range will drill more slowly. The circuit needs to run both ways so you can reverse the auger to free it. If your excavator only has a single-acting hammer circuit, the optional 2-way valve converts it to two-way flow. Quick couplers aren't included: Auger Torque recommends plumbing it in directly for the best flow. Check your machine's auxiliary flow and pressure before you order, or send us your machine details and we'll check them for you.

Fitting It to Your Excavator

Machine weight is the starting point, but excavators in the same class use different pins, dippers and quick hitches, so the hitch is made to measure. When you order, send us:

• Your excavator make, model and operating weight
• Front and rear pin diameters, pin centres and dipper width
• Your quick hitch make and model, if you use one
• Your auxiliary circuit's flow and pressure, if you know them

Our guide on how to measure an excavator for a new bucket shows how to take the pin measurements, and they're the same for an auger hitch.

Delivery and Ordering

We confirm the earth drill, hitch and hydraulics suit your machine before anything is supplied. Delivery is usually within 7 to 10 working days, although factory lead times can change this. If you need it for a fixed date, contact us before ordering so we can confirm the current lead time.

20000 MAX Earth Drill FAQs

What size excavator does the 20000 MAX suit?

Auger Torque recommends it for 13–20 tonne excavators. Your machine's auxiliary circuit also needs to supply 80–170 l/min at 160–240 bar.

What size holes can it drill?

From 150mm to 1,000mm across with Auger Torque S6 augers, depending on the ground.

Does it come with a hitch and auger?

No. It comes with hydraulic hoses, and you choose the hitch and S6 auger separately, so you get the right pin size and hole diameter.

What hydraulics does it need?

A two-way auxiliary circuit that supplies 80–170 l/min at 160–240 bar. A single-acting hammer circuit can be converted with the optional 2-way valve.

Which augers fit it?

Auger Torque S6 augers with a 75mm square hub. See the S6 auger for diameters and teeth.

Other Sizes
