1、 Tips for choosing a seed roller

1. Material selection:

-Rubber wheels: Good elasticity, suitable for clay or damp soil.

-Metal wheels: Strong durability, suitable for gravel ground, but need to be equipped with buffering devices to prevent damage to the seeds.

-Composite material wheels: combining the advantages of rubber and metal, with high price but excellent comprehensive performance (recommended brands: John Deere, Case IH).

2. Size matching:

-The wheel diameter is usually 30-50cm, which needs to be selected according to the type of seeder. For example, it is recommended to equip a 6-row seeder with a 40cm wheel diameter to ensure even grounding pressure.

-The width of the wheel affects the compaction area. Narrow wheels (10-15cm) are suitable for dense planting of crops, while wide wheels (20cm or more) are suitable for large seeds.

3. Pressure regulation function:

-It is preferred to use a pressure wheel with hydraulic or spring adjustment, such as a pressure range of 50-200N (referring to ISO 7256 standard), to adapt to different soil hardness.

4. Additional feature considerations:

-Anti entanglement grass design: The wheel with self-cleaning structure can reduce weed accumulation, especially suitable for no till sowing.

-Adjustable pattern: Change the wheel surface pattern according to different crop needs (such as V-shaped pattern suitable for corn, plain weave suitable for soybeans).

5、 Maintenance and usage suggestions

1. Regularly check the wear of the wheel surface, and replace the rubber wheel immediately if it cracks.

2. Adjust the pressure to the appropriate value of the soil before operation. Overpressure will cause soil hardening (recommended test pressure: 80 N for sand and 120 N for clay).

3. When stored for a long time, clean the wheel body and apply anti rust oil to avoid direct sunlight on the rubber parts.

Based on the above analysis, users can choose cost-effective seed rollers according to actual operating conditions, significantly improving sowing efficiency and crop yield.
