Degelman Pro-Till

It only takes on pass to prove the high performance of the Degelman Pro-Till by leveling ruts, crushing dirt clods and mixing residue to create a desirable fine tilth seedbed.
It only takes on pass to prove the high performance of the Degelman Pro-Till by leveling ruts, crushing dirt clods and mixing residue to create a desirable fine tilth seedbed.
A Pro-Till cultivator has the unique ability to cultivate and warm the soil during cold wet conditions when all other forms of tillage plug and fail. In the midst of a long wet spring, getting seed in the ground allow adequate time for the growing season is crucial. Heavy cold soils need to be black and warm for ideal germination conditions. In as little as one day and after one pass, frigid heavy residue soil is cut, turned, mixed, reactivated, warmed, topically dried and ready for planting/seeding. Pro-Till in the spring can mean the difference between success and failure.
