Bluebird NEA 521-ESS
Professional Earth Auger for Intensive Use

Bluebird NEA 521-ESS - Professional Earth Auger with 4-Stroke Petrol Engine

The Bluebird NEA 521-ESS is a professional earth auger designed to tackle demanding drilling jobs in the agricultural , forestry , and construction sectors, even on steep, rocky, or steeply sloping terrain. This model is intended for expert operators who need a reliable, durable, and high-performance machine capable of completing piling, reforestation, and fruit tree planting jobs quickly, precisely, and safely, even in difficult operating conditions.

The Bluebird NEA 521-ESS petrol earth auger combines a solid, heavy-gauge steel frame with a highly efficient 4-stroke engine , ensuring smooth power transfer and total control of the auger while drilling. Its key features include a hardened steel gear reducer , an ergonomic double handle for optimal stability, and the ability to drill holes up to 200 mm in diameter , making the NEA 521-ESS earth auger a complete technical tool, ideal for professionals in the agricultural and forestry sectors .

Drill NOT INCLUDED.

TECHNICAL SPECIFICATIONS

The Bluebird NEA 521-ESS is equipped with a 4-stroke engine that ensures constant power and effective lubrication even during prolonged operations. The 0.98 L fuel tank guarantees extended working hours, while the recoil starter with decompression valve makes starting easier and reduces operator fatigue. Thanks to the petrol engine , the earth auger can be used completely autonomously without an electrical connection, ideal for remote terrain or isolated construction sites.

In terms of performance, the engine develops 1.25 kW (1.68 HP) with a displacement of 43 cc , reaching a maximum speed of 6500 RPM . The case-hardened and tempered steel gear transmission ensures reliability and uniform transmission of torque to the auger. This heavy-duty earth auger allows drilling up to 200 mm in diameter , maintaining an excellent balance between power and maneuverability thanks to its 9.8 kg empty weight without the auger . The auger can be purchased separately , allowing the equipment to be customized according to specific operational needs.

FUNCTIONAL SPECIFICATIONS

High performance 4-stroke professional engine

The Bluebird NEA 521-ESS is equipped with a 4-stroke engine designed to offer high performance while maintaining low fuel consumption and emissions. Thanks to constant torque and immediate response , this earth auger ensures efficient drilling even in compacted or deep soil, making it ideal for intensive professional use in agriculture, forestry, and construction.

Gear reducer with hardened steel gears

The 40:1 gear reducer uses case-hardened and tempered steel gears , ensuring smooth and reliable power transmission over time. This system converts the engine's high rpm into controlled rotation of the auger, ensuring precision and safety during all drilling operations.

High-strength steel auger and cutting elements

The steel auger , along with the hardened tip and cutter, is designed to tackle hard, resistant soils, reducing wear and increasing the life of the drilling components. This configuration limits vibration, reduces operator fatigue, and allows for precise and rapid drilling of holes, increasing overall work efficiency.

Ergonomics and control for intensive professional use

The ergonomic double handle and optimized throttle ensure maximum control of the earth auger even in difficult conditions. The carefully designed balance and layout of the controls reduce operator fatigue, increase safety, and allow for prolonged use without compromising precision.
