БДТ 2.

Technical Analysis of the БДТ 2 Disc Harrow

The design of the БДТ 2 follows the classic heavy-duty disc harrow architecture, optimized for intensive primary tillage. Its primary purpose is to handle challenging field conditions, such as post-harvest residue, thick sod, and fallow land, where high pressure per disc is required to effectively cut through and incorporate vegetation into the soil profile.

Disc Section Geometry

The operational efficiency of the БДТ 2 is centered on its adjustable disc gang angles. This feature allows operators to fine-tune the aggressiveness of the tillage based on specific soil moisture and density levels. With an attack angle of up to 21 degrees, the unit ensures optimal soil inversion and effective weed control. Depending on the soil condition, different combinations of notched (scalloped) and plain discs can be employed to achieve the desired soil structure.

Durability and Engineering Solutions

Reliability in demanding field environments is achieved through several key design choices:

• Gang Axles: Constructed from high-strength alloy steel to withstand bending moments when encountering stones or hard spots in the soil.
• Sealed Bearing Assemblies: Feature specialized dust and moisture seals to prevent abrasive particle ingress, thereby extending service intervals.
• Main Frame: A robust, welded box-section design that effectively dampens vibrations and resists fatigue during high-speed operations.

The trailed hitch mechanism provides excellent maneuverability, allowing for tight turns at headlands while minimizing soil compaction. When the operating depth is properly calibrated, the БДТ 2 maintains a consistent performance without lateral drift, thanks to the precise weight distribution across the frame and the balanced center of gravity of the disc gangs.
