Wallace,
I know this is an old thread but I have been doing some searching in the past few months and have identified that the 3616 pictured in your post in this thread is "the" tractor I bought last year. I know this because of the narrow black fenders, red step and low flashers on the rear of the cab. These features are not the same on any other 3616 cabbed tractors that I can find. It appears that these items were changed prior to final production of this model. I'm contacting you because I'm interested in any other photos that you may have of this tractor. I noticed the image you have above is a unique photo that appers to have been taken by you. Do you have any others that you can share with me? Thanks.
I also forgot to mention that this tractor does have the front side headlights installed and functioning. Apparently this is also an option that was never installed or offered in the production models.
