Quick-coupling system for a replaceable working assembly of a snow grooming vehicle

A snow grooming vehicle comprising:

• a main frame configured to laterally support a plurality of tracks and support a driver cab;
• a support frame coupled to one of a front of the main frame and a rear of the main frame;
• a working assembly configured to refine a surface as the snow grooming vehicle advances;
• a preexisting coupling interface between the support frame and the working assembly, wherein the preexisting coupling interface is formed by corresponding portions of the support frame and the working assembly and configured to enable a selective coupling of the working assembly with the support frame;
• and
• a quick-coupling assembly configured to selectively couple the working assembly to the support frame, the quick-coupling assembly being at the preexisting coupling interface between the support frame and the working assembly and comprising a first coupling body coupled to the support frame at the corresponding portion of the preexisting coupling interface, and a second coupling body coupled to the working assembly at the corresponding portion of the preexisting coupling interface such that an indirect coupling between the support frame and the working assembly is mediated by the quick-coupling assembly to form a new coupling interface.
