REA20000 Auger Drill Details

earth auger parts


Standard with all Auger Drives in areas that we know will take a lot of strain. All hood pins are locked for extra safety making it impossible for the hood to detach from your hitch


EATON Motor provide stable and high torque power output. The failure rate is only 0.2%


Torque is amplified by using the unique  planetary gearbox. This system allows the motors output torque to be multiplied with extreme efficiency as well as ensuring the durability and reliability you need.


The Non-Dislodgement Shaft is a single piece drive shaft assembled top down and locked into the Earth Drill housing. This design guarantees that the shaft will never fall out, making for a safer work environment, not only for the operator but also any surrounding workers, a MUST-HAVE FEATURE for any safety conscious company.


All Auger drives come standard with high quality hoses and adaptors (excludes larger units. QRC’s not included).

Excavator Earth Auger Specification

The efficiency mainly refers to the rotating speed whicj according to the oil flow of the excavator. Different working conditions and the proficiency of operators also affect it.

We have a client who can dig 1,500 holes in a day. His excavator is 6 tons with 350mm diameter and 500mm depth. And There is also a customers use 7 ton excavator with diameter 700mm & depth 1.8m, just 100 holes within 8 hours.

A:No, we haven’t met this condition so far.

3.Q:What’s the gear box used for in the auger drive?

A:The planetary gear is used for transmission. Gear box is used for slowing down the speed of motor.

4.Q:In which condition, earth auger can work most efficient?

A:Efficiency depends on rotate speed. Rotate speed depends on oil flow. Oil flow depends on the excavator pump.

5.Q:In common earth condition, how many holes can be dig in 1 min?

A:Different earth condition has different answer. It depends on the oil flow and pressure, whether the earth loose. For example, it takes 30s to dig a dia 300, depth 1.5m hole in loose earth.

6.Q:How long should change the auger teeth?

A:It depends on the earth condition and working time. According to customers’ feedback, it would be 6 months in loose earth and 1-3 moths in soil with small stones.

7.Q:What’s the space between two screw blade?

A:It depends on the auger type and the outer diameter.

8.Q:What’s the material of screw blade?

A:Q345 alloy steel.

9.Q:Why the output shaft of REA2000-4500 is round, and REA5000-25000 is square?

A:Large type of auger drive has bigger torque. Square output shaft can increase the friction and hard to slide.

10.Q:In which condition, the auger drive won’s work.

A:The hose was not connected correctly. The excavator problem. The motor problem.

11.Q:How about the warranty?

A:We provide 18 month warranty for our auger drive.(Under the correct operation)

12.Q:How many teeth does S4,S5,S6 auger have?  According to diameter of the auger?

A:Yes, according to the auger’s diameter.

13.Q:Why don’t fully weld between screw blade and auger?

A:Because fully weld will make the auger deformation.

14.Q:Will the teeth holder be deformed.

A:It will be worn but won’t be deformed.

19.Q:What kind of machine can auger drive be installed?

A:Excavator, crane and skip steer loader.

20.Q:What’s the material of the pin hitch?


21.Q:Why the thickness of screw blade is different? What’s the thickness of central pole? Why the thickness of central pole is different?

A:Because of different type, big torque will make the auger broker.

The thickness of central pole: S4 6mm, S5 8mm, S6 12mm.

22.Q:Why don’t make auger longer, a 2-3m long?

A:We can do this, but it may not be lift up.
