Väderstad Seeding Disc Sweetcorn 490846-M

OEM Sweet Corn Seed Metering Disc for Väderstad Tempo Precision Planters

Product Overview

The Väderstad Seeding Disc Sweetcorn 490846-M is a precision-engineered seed metering disc designed for planting sweet corn (sweet maize) using Väderstad Tempo high-speed precision planter systems.

The seed disc is one of the most critical components in the seed metering unit. It controls seed singulation, spacing, and release timing, ensuring that each seed is accurately picked up and delivered into the seed tube. Proper seed disc selection is essential for achieving uniform plant emergence, optimal population density, and maximum crop yield.

The 490846-M Sweetcorn Disc is specifically designed for sweet corn seed characteristics, including seed size, shape, and weight. It works together with the vacuum metering system to ensure precise seed selection and accurate placement at high planting speeds.

At Dawopu, we manufacture OEM-quality replacement seed discs with high dimensional accuracy, excellent wear resistance, and reliable performance for modern precision farming applications.

Function of 490846-M Seeding Disc

The seeding disc performs several critical functions:

• Picks up individual sweet corn seeds using vacuum pressure
• Separates seeds to ensure single-seed placement
• Controls seed release timing
• Maintains uniform seed spacing
• Reduces skips and doubles
• Supports high-speed planting operations
• Improves overall planting accuracy

The correct seed disc directly affects stand establishment and final crop yield.
