BlackStone AR400 - Lawn Scarifier with Fixed Blades - B&S CR950 Engine

The brand-new Blackstone AR400-BS950 hand-pushed lawn scarifier and raker is an essential machinery for keeping your green space always clean and aerated.

Machine equipped with heavy-duty housing.

Main functions:

• Cleaning the moss from lawns
• Easily scarifying the weeds
• Collecting the grass

It is equipped with rotor with blades and springs:

The rotor with 18 blades scarifies the soil, acting vertically and deeply thanks to its blades, improving oxygenation, drainage and nutrient uptake;

The rotor with springs, which number vary depending on the model, combs the lawn, removing the layer of felt and moss that has formed and preventing regrowth.

Compared to competitors, which are usually powered by 163 cc engines, this scarifier is powered by a Briggs & Stratton 208 cc engine which develops up to 6.5 Hp.

Why use a lawn scarifier:

• Over time, turfs tend to create a layer of felt that prevent the oxygenation of the soil with the consequent suffering of the lawn.
• It is advisable to use the lawn scarifier to remove the felt layer and create grooves on the ground that will facilitate contact with air, fertilisation and lawn reinforcement.

It is provided with a 40 cm working width.

The rotor allows an efficient and safe working.

Adjustable working depth from 0 to 15 mm. This makes this scarifier a truly versatile product, able to meet the needs of different users.

Ultimately, the Blackstone AR400-BS950 guarantees excellent results on all types of terrain.

This model is equipped with a 45 L collection bag.

This lawn scarifier is equipped with 2 different types of rotors, easily interchangeable.

Rotor with springs: recommended for the “aeration process”, it consists of a sturdy roller fitted with 24 springs.

With this rotor, the turf is combed lightly thanks to its steel spring design, which pinches and pulls away the felt and moss (also preventing regrowth).

Rotor with blades: recommended for the “scarifying process”. It consists of a steel roller fitted with 18 fixed blades.

This rotor type allows a more intensive lawn care thanks to the possibility to work the soil in depth. Indeed, the sharpened 18 blades penetrate vertically the lawn allowing the complete removal of moss, felt and weeds.
This feature allows the lawn to regenerate by improving oxygenation, drainage and nutrient uptake.
