Description
Chains (anchor or Ely) and chain harrows can be used to help prepare the seedbed and incorporate seed after wildfire. These methods are also effective for providing variable planting depths for diverse mixtures. Anchor chains are pulled in a U- or J- shape between two tractors or dozers and chain harrows are pulled by a single tractor or dozer. The chain harrow can be paired with a seed broadcaster for single pass seeding. Seeding only requires on one pass over the site to cover the seed, so seed should be applied before the final pass.
Application
Considerations:
- Ely chains and heavier chains cause more ground disturbance, and can be more difficult to pull. Ely or smooth chains should be pulled in a “U” or “J” shaped
pattern. If pulled too straight, the chain can skip over the ground. Soil contact should be maintain for best seed incorporation. - Although chain harrows are rugged, large rocks and very rough terrain can damage tires, axles and other parts.
