A little plastic toy tractor I've had for years, probably originally part of a miniature farm set. Unfortunately, no maker's name is to be found. Anyway, it's a nicely detailed little four-cylinder row-cropper, showing the exhaust manifold, carb and air cleaner on one side and the plug wires, distributor and generator on this side.
I especially like the posture of the operator with his peaked cap, holding onto the metal seat with his right hand and gazing off to the right as he presumably begins to make a turn. Note the selector levers below the steering column. There was a lot of accuracy put into the mold for this cheap little toy.
And, unlike Mister G's example, he's managed to keep his head!
