Abstract: An improved net cutting assembly that may be used with an agricultural baler net wrapping system. More particularly, an up-cut net knife for improved cutting of wrapping material (e.g., a net) used to wrap bales of crop material in an agricultural baler. The up-cut net knife assembly improves net cutting performance by providing an up-cut net knife that moves in the same direction as the net whereby the motion of the net helps the knife get into the cut position.

In the cut position, the knife stops and the net is pulled against the knife blade resulting in cutting the net.
