At first glance, I was inclined to agree with George. I too had a yellow one. But after further investigation, I would have to agree with THawley. I knew Sears to make this type unit in yellow, blue, and orange. (i know, it could've been painted red) but even moreso, I never knew the Suburban to NOT have the high/low transmission in it. I could be wrong, but several of our neighbors had the Suburbans, different colors, but all had the granny gear (high/low range) transmission that I do not see on this one. If there are any numbers on it anywhere, that may give a better clue, especially if the model number begins with a 917. XXXXX. This would indicate a Roper-made Sears unit.
