Newbie-Thought Id share my 770 Ochard

Heres a video of my 1958 770 diesel Orchard. We were in the citrus business growing 120 acres of hamlin and Valencia oranges. My grandfather bought this tractor new from Hutchinson tractor and Equip. in Eustis FL. I started disking and spraying in my early teens and have logged many hours riding this old girl. Olivers were used by many of the grove managment outfits in central Florida and was only challanged by Case which was distributed locally by Pounds Motor Co. of Winter Garden FL. I can truthfully attest that Oliver tractors were easier to handle and not as tiring to opperate as were the DO and 430 Case grove tractors we had also. We sold the grove in the early 1990's after the freezes of the 80's took their toll. Notice the 550 in the video as well. It too was purchased in 1958. Also notice the bracket on the rear of the right fender as the 770 goes by. Can anyone guess what this bracket was used for?
