Proudly Presents:

What model is that "Johnny Popper"?

    The secret of telling the Two-Cylinder tractors apart is to sneak up on them and read what it says on the serial number plate! The plate is usually aluminum or brass, and is located in different places on different models.
   Seriously, if you can't get close enough to do that, let me point out some of the major differences. I have prepared some pages with pictures of each model. I can't show every variety of each model, but perhaps I can show you enough examples to help you identify which model you are looking at. If you click on the links below, and then click back and forth on the models that are being compared, some of the similarities and differences will be pointed out for you.
    Since the purpose of these pages is to help you IDENTIFY the tractors, we will concentrate on the visual details and only point out the technical differences if they help with the identification.
    If the tractor still has its original "Model Designation Decal" on it, your job is DONE. If not, read on...

    Okay, So...... What Models are we talking about?
