How does
the machine work?

Purpose

The heavy spring harrows perfectly level the field surface by copying the relief of the field. They distribute crop residues evenly over the field. In early spring, the harrows are used to close the moisture.

Crop residue management

Closing capillaries

Fallow-land processing

Provocation of fallen seeds and weeds

ADVANTAGES

RELIABLE SUPPORT

We know how important it is to retain moisture in the soil for your future harvest. Start your work in the field 1 to 2 days earlier with tandem support wheels. The suspension on balancers will provide perfect terrain following

A ROUGH FIELD IS NOT A PROBLEM

The section width of 1.7 m in combination with the section suspension enables even hilly meadows to be worked evenly

OPERATE WITHOUT LEAVING THE TRACTOR CABIN

Achieve the desired cutting quality from the comfort of the tractor cab by hydraulically adjusting the angle of the tines (BT-9G; BT-9.EU and BT-12.EU only)

INCREASED MARGIN OF SAFETY

The large safety factor of the frame increases the service life of the implement

RELIABILITY AND DURABILITY

The rope balance system of the frame compensates for peak loads, protecting the most loaded parts of the unit, and thus extends the service life of the implement

THE DIAMETER AND LENGTH OF THE SPRING HARROW TINE

The 14 mm diameter and 675 mm long tine is highly robust and reaches the required vibration frequency at 12 km/h, unlike 16 mm diameter tines which require higher speed. This allows you to work effectively in uneven fields where high speeds are not possible
