This model came just at the time when contractors, municipalities, and fleet managers were insisting on cleaner engines, smarter controls, and better operator comfort without losing the rugged reliability that the 140 series was known to possess. The M3, in most respects, did not abandon the tradition of the previous 140 models; it perfected it.
