The Celli Spading Machine
is an articulating spader. The spades work like a hand shovel on a crank shaft. Each spade shovel takes a turn entering the soil, so very little horsepower is
needed to operate it. This makes it the ideal primary tillage tool for low horsepower tractors. It can also till damp ground to open it up and dry it
out for early spring plantings. These are the two main advantages over the chisel plow.
Like the Chisel Plow, it can be adjusted to till deep or shallow and can till one
bed at a time. The Spading Machine is the ideal tillage tool because the spading action completely loosens the soil across the bed and its motion does not
compact or smear the soil at the bottom of its travel. However, spading machines do not "double dig" and will invert soil with repeated use .
