Tracked vehicle for finishing the ground, in particular a snow grooming vehicle, with a replaceable working assembly

A tracked vehicle comprising:

• a main frame configured to support a plurality tracks laterally and a cabin above;
• a supporting frame coupled to at least one of a front of the main frame and a rear of the main frame;
• a working assembly selectively releasably couplable to the supporting frame and configured to finish a ground during advancement of the tracked vehicle;
• a coupling assembly configured to selectively couple the working assembly to the supporting frame, wherein the coupling assembly is switchable between:
• a first configuration in which the coupling assembly enables the supporting frame to reach a coupling position with respect to the working assembly to be mounted, and
• a second configuration in which, from the coupling position, the coupling assembly constrains the working assembly to the supporting frame;
• and
• a monitoring device configured to:
• monitor, at least in a final stage of the supporting frame approaching the working assembly to be mounted, a reciprocal position of the supporting frame with respect to the working assembly and
• during at least the final stage, generate a signal representative of the relative position of the supporting frame with respect to the working assembly.
