All of these models were very similar.  All were based on a chassis with a mid-mount motor, and bogie wheel suspension/solid rubber track.  The model number denoted the engine size/accessories, although the number does not match the engine size.  All models had either a Walbro or Bendix carb - this varied often.

Note: CCW and Kioritz are the same engine.  CCW (Canadian Curtis Wright) was the company that imported the engines to North America in the earlier years.  Starting in '74-'75 Deere bypassed them and used the manufacturer's name instead (Kioritz).  Kioritz is still in business making engines, and is associated with ECHO.
