A novel structure is provided for joining a frame member for carrying a snowplow blade or the like to a vehicle-mounted lift frame or the like. At least one mounting bracket is rigidly attached to the lift frame and includes a pair of parallel, generally vertical walls supporting a generally horizontal mounting rod therebetween. A cooperating mounting ear is provided on the blade-carrying frame and is of lesser width than the space between the parallel walls of the mounting bracket. This mounting ear presents a slot of predetermined depth which is rotatably engageable with the mounting rod to define a rotatable joint. A retaining pin is insertable through the mounting bracket vertically above the mounting rod and substantially parallel therewith. The space between the retaining pin and the mounting rod is sufficient to allow some vertical play in addition to rotation of the mounting ear with respect to the mounting rod but of lesser extent than the predetermined depth of the slot in said mounting ear so as to prevent disengagement thereof. A lift arm link is removably mounted at an upper portion of the lift frame and positioned for transmitting motion between a lifting piston and the blade-carrying frame member to effect lifting and lowering of a snowplow blade. This lift arm link is also mountable to the blade-carrying frame for holding the mounting ear above the ground at a level substantially similar to the level of the mounting rod to facilitate engagement or disengagement thereof.

Apparatus for joining a frame member for carrying a snowplow blade or the like to a vehicle-mounted lift frame or the like, comprising: at least one mounting bracket member rigidly attached to said lift frame and including a pair of parallel, generally vertical walls supporting a generally horizontal mounting rod therebetween, means forming at least one mounting ear on said blade-carrying frame, said mounting ear being of lesser width than the space between said parallel, generally vertical walls of said mounting bracket member and having a generally vertically oriented slot therein of predetermined depth, said slot being rotatably engageable with and over said generally horizontal mounting rod to define a rotatable joint, a retaining pin, and means in said mounting bracket member for removably receiving said retaining pin generally vertically above said mounting rod and substantially parallel therewith, the space between said retaining pin receiving means and said mounting rod being sufficient to allow relative rotation of said mounting ear with respect to said mounting rod but of lesser extent than said predetermined depth of said slot in said mounting ear and further including a lift arm link mounted at an upper portion of said lift frame and positioned for transmitting motion between a lifting piston and said blade-carrying frame member to effect lifting and lowering of a snowplow blade or the like mounted to said blade-carrying frame member, means for removably mounting said lift arm link to said lift frame including a lift frame bracket formed in said lift frame and cooperating apertures in said bracket and in said lift arm for receiving a pin, thereby rotatably mounting said lift arm link to said lift frame, and means on said blade-carrying frame for removably mounting said lift arm link to serve as a stand for holding said mounting ear above a ground surface at a level substantially similar to the level of said mounting rod to facilitate interengagement therebetween.
