Isn't this a sweet little tug you would like to see out on your tarmak? Museum member Scott Stetlze brought this little baby to the museum completely restored.

This tug is an exceptional example of a four cylinder Clark CK-20 tug. This tug has been completely dis-assembled and made fully operational. It is a four cylinder gas powered tug and weighs approximately 3800 pounds. The running gear is a four cylinder flat head, liquid cooled Continental engine.

The tug was completely overhauled and improved. It has a stereo system. retractable antenna, diamond tuck seat, spin off oil filter, new electrics, headlight, tail-light, front and rear pintle hitch. Tow capacity is 20,000 pounds according to Clark literature and this is best used for a single point tow bar.

You would be hard pressed to find too many other existing examples of these tugs. For their lightweight, and the advent of commercial air travel, these tugs would likely be found living out their life towing baggage around a terminal and long since retired.
