Thank you Chris for all the nice words. I know it is kind of difficult to understand what it is, also because I'm building it without plans, what is on my mind goes to this build. The stock tractor has a straight frame, mine is all curved, because the idea is to have the tractor do a wheelie, I think it will help to give to the final scene a "movement".
I like tractors, above all those old American tractor with the two wheels almost attached in the front, in Europe, or at least in Italy they never made them so. Only tractor with wide front axle. Plus I think a narrow front axle I think it looks more cartoonish.
Here a picture with the tractor that inspired me and I'm trying to build.
