Jacobs & Co. would inform the Farming Public that they are manufacturing at Dayton several kinds of Ploughs, which have been heretofore approved, to which they invite the attention of those wishing to buy. These ploughshare – made of the best material, and warranted to be perfect in every respect – They are also manufacturing the improved revolving Colter, which is acknowledged to be far superior to the common straight ones. Call and examine for yourselves.
Old ploughs will be repaired to order on reasonable terms.1
The revolving colter was an improvement on the previous form, which was a vertical knife edge to cut through roots and vines. A fixed knife collects roots and vines and tends to plug up. The rolling blade greatly reduces the friction through the ground and does not gather rubbish on its edge.
Another Dayton company in the forefront of technological advancement!
