A wing plow assembly may include a base configured for attachment to a vehicle; an upper arm rotatable about a first axis; a lower arm rotatable about a second axis; a lifting member rotatable about a third axis; a support pivotally attached to the upper arm and the lower arm; and an actuator pivotally attached to the base and the lifting member; wherein the actuator is configured for raising and lowering the support by engagement of the lifting member with the upper arm; wherein the lifting member is rotationally decoupled from the upper arm such that the upper arm is disengageable from the lifting member. At least one of the first axis and the second axis may be configured to be substantially parallel to a longitudinal axis of the vehicle.

Wing plow apparatus

A plow may include a main plow body, a plurality of trip edges hinged to the main plow body, at least one spring sharer hinged to the main plow body, and a plurality of springs each of which is configured to resist rotation of one of the plurality of trip edges and/or the at least one spring sharer. The at least one spring sharer may be configured for engagement with at least two of the plurality of trip edges, and at least one of the plurality of springs may be configured to resist rotation of at least two of the plurality of trip edges via engagement with the at least one spring sharer.

Plow trip edge spring sharer

A spreader assembly may include a hopper configured for receiving a spreadable material, a removable cartridge configured for sliding engagement with the hopper and having a material transportation mechanism configured for receiving the spreadable material from the hopper, and a spreader configured for receiving the spreadable material from the material transportation mechanism and spreading the spreadable material onto a target surface. One of the hopper and the cartridge may include a roller having a roller surface, and the other of the hopper and the cartridge may include a bearing surface configured for rolling engagement with the roller surface. The cartridge may have one or more pull bars to facilitate removal of the cartridge from the hopper. Related methods are described.
