The BT model produced by Landstal is a type of short disc harrows that are increasingly used in modern agriculture, and the reason for this is their practicality and universality of use. This type of machine is ideal both for crushing and mixing the plant mass with the soil, as well as for breaking up clods and preparing the seed bed. By mixing plant residues with soil, a bed is obtained that is rich in shredded humus, which contributes to soil preservation and increased yield.
A large distance between disc sections of even one meter enables work without congestion, and the large disc diameter of 560 mm (optionally 610 mm) ensures easy traction and high working speed, and therefore high work performance. At the same time, each disc is independently connected to the main frame by means of a rubber suspension that ensures better shredding of crop residues and crushing of lumps. Also, it is important to point out that the disk bearings are closed and do not require lubrication, and the disks themselves are made by Italian manufacturers OFAS and AMA, and are made of high-quality anti-abrasive steel alloys.
Fixed frame versions are available measuring 2.5, 2.7, 3, 3.5 and 4 m.
In order to make the work of the BT plate as efficient as possible, depending on the type of soil, it is possible to choose between as many as 14 different types of rear rollers.
