Advantages:

The harrow structurally consists of two rows of concave spherical discs, the axes of which are directed from the center. The success of using sowing discs is based on the fact that they are designed for optimal opening of the furrow.
Bellota discs, made of boron steel with a sharpened cutting edge, have an optimal geometric surface for performing the selected type of work. High accuracy and wear resistance guarantee uniformity of soil treatment. As a result of using the strictest high-quality standards,seeding discs Bellota are more cost-effective, as they have a longer service life with less wear, which reduces the cost of acquisition. That's why the world's leading manufacturers of sowing machines choose Bellota seeding discs.
The same hardness of the entire disc is guaranteed by the use of an automatic heat treatment control system during its manufacture. This hardness ensures the elasticity and maneuverability of the disc, allows it to absorb shocks without damaging the disc, so the service life isdisk harrows sufficiently large even with the most unfavorable soil characteristics.
The above advantages allow you to increase the service life ofdisc harrows without repair twice (up to 5..7 years).
