A quirky, rare 3 wheeler, the “Mud Bug” was made by MTD, a company known more for producing lawn mowers. Powered by Briggs & Stratton motors varying between 5-8 horsepower, they were designed to be fun toys that could be transported in a station wagon, back when people actually bought station wagons.
Options included a luggage rack, light kit, or even a ski to replace for the front wheel. For more information on the Mud Bug (and some vintage ads), check out this write-up on 3 Wheeler World.

This example is claimed to be in very good condition with original paint, a Comet clutch, new seat, and a functioning pull start.
