Vaderstad Rotor 101204-M

OEM Seed Metering Rotor / Distribution Rotor for Precision Seeding Systems

Product Overview

The Horsch Rotor 101204-M is a precision-engineered rotating component used in agricultural seed metering systems, typically installed in Väderstad-type and compatible precision seeding units that are widely applied in modern seed drills and pneumatic distribution equipment.

This rotor is commonly known as a seed dosing rotor / metering rotor, responsible for controlling the flow, timing, and separation of seeds during the planting process. It works inside the seed metering housing, rotating continuously to ensure that seeds are evenly and accurately delivered into the air stream or drop tube.

Based on agricultural spare parts references, 101204 / 101204-M is a widely used rotor for seed metering mechanisms in precision seeding equipment, particularly for Väderstad Rapid and BioDrill systems.

At Dawopu, we manufacture OEM-quality replacement rotors designed for high precision, wear resistance, and stable performance in modern agricultural machinery.

Function of Rotor 101204-M

The rotor performs several critical functions in the seeding system:

• Controls seed metering and discharge timing
• Ensures consistent seed flow into distribution channels
• Prevents double seeding or seed blockage
• Maintains accurate planting density
• Supports high-speed precision planting operations
• Stabilizes seed delivery under varying field conditions
• Improves overall sowing accuracy and crop uniformity

In precision agriculture, rotor stability directly impacts yield consistency and planting quality.
