It also includes a first side plate attachable to a first side of the plow body, and a second side plate attachable to a second opposite side of the plow body. The sectional plow also includes a first thrust arm attachable to the plow body and the first side plate, and a second thrust arm attachable to the plow body and the second side plate. In an embodiment, the thrust arm is a pair of thrust arms.
