Once, Willie and his tractor were late to deliver a load of wool, and he did not secure the bales properly. Unfortunately, due to Willie's carelessness and an overloaded trailer, the load slipped onto the line, causing Rex to crash into it and derail.
Willie's tractor is based on a Ford 50000 tractor. Several other tractors share the same basis.
The tractor had headlights, resembling eyes.
Willie's tractor was painted purple.
