This is roughly a 1950 early American potato tractor. The wheel track is 4 and a half foot wide, same distance as the spacing between rows of potato's. This is 1/87 scale and ONLY going to be opened in FUD material only.
This turns out to be one of the few farm tractor designs that went to Europe under The Marshall Plan which started in 1948. Here is a link to a Youtube page showing this.
Note please, you have to gently detach the wheels from the tractor. We put a bar to hold the wheels for production. 1 end of the bar connects to the front axle, so be very careful removing it.
To make this under the French design, simply cut the exhaust off the top of the engine cover, and attach it to the bottom left side, near the rear of the engine. Then just make an exhaust pipe to come down to it.
