Description Knapp sidehill plow, 1908. Iron, painted black, and oak wooden plow with arrow-shaped double-sided blade. Wood has clear varnish with black painted handle grips. There is a small iron wheel in front mounted between two V-shaped iron brackets. An iron rod with a looped end extends between handles and is used to adjust which side blade is on so the farmer can keep rows going in the same direction as he plows back and forth perpendicular to the slope.

Notes Knapp Side Hill Plow, 1908
Hillside or turning plows are used for plowing on steep ground. Rotating the cutting part of the plow allows the operator to turn at the end of each row and continue to push the dirt downhill.
A unique feature introduced with the Knapp Side Hill Plow is the simple locking device that keeps the plow in place when adjusting the blade. The blade may be locked or unlocked by twisting the iron loop between the handles. This allows the farmer to turn the blade without having to let go of the plow or the animal harnessed to it .
