This Holt Caterpillar tractor engine with dynamo was made by Ron Schindele, of AZ, in 2011. This is Ron’s extraordinary rendition of the well-known Holt Caterpillar engine sold by Cole’s Power Models. Ron designs and fabricates his own propane carburetors, and this example runs extremely clean, smooth, and manages workloads quite easily.

His custom wound dynamo puts out about 40 volts and is mechanically coupled to a miniature generator for effect. The engine itself is 7″-long, 5″-wide, and 7″-high. The full display measures 23″-long, 10″-wide, 15″-high, and weighs 35 lbs.
