This is a must-have! The drag harrow I purchased last year exceeded my expectation for cultivating the field and seedbed preparation. After seeding, I just turn the drag harrow over to smooth the seedbeds. It is multifunctional only by adjusting steel tines.

This drag harrow is great and does a good job. What are you waiting for? Come and have it!
