Abstract
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 t…
