Does anyone remember the Growing O dealer demonstrations? They were company sponsered dealer get-togethers designed to show off Oliver products to the dealers and assit them in ways to promote the line. I think they were going on about 1970 or so. My father and I attended one in the Harrisburg, PA. area if memory serves me correctly. Oliver had just come out with the 1950T  and the brass was pulling out all the stops promoting the 1950T. For the fuel efficency demo, they had a dual wheeled T teamed with a 6X18 speedex bottomed plow compared with a 1256 IH and an 1130 Massy. They were plowing sod, if memory serves me. The T was the most efficent, the 1130 was next and the 1256 used a good 33% more fuel than the Oliver. Massy had some load and draft affair that was supposed to dramaticaly increase traction on their 2WD's. Oliver countered it with their own version. I remember that somebody screwed up on that demo because the Massy unit demonstrated far less wheel slippage than the Oilver version. Didn't take long to truck us to the next demo <!-- s:lol: --><img src="{SMILIES_PATH}/icon_lol.gif" alt=":lol:" title="Laughing" /><!-- s:lol: --> Any of you fellows remember those promo's?
