To prevent damage to the low-hanging branches in citrus orchards, tractor manufacturers made “orchard” versions. The large rear fenders kept the tractors from damaging the trees. The McCormick-Deering shown above was only made in 1938 and 1939.
“March 1939. Two ‘Caterpillar’ Diesel D2 Tractors disking in 5000-acre vineyard at Guasti, California. Working 9 hours a day, each D2 uses 1-1/4 gallons of fuel per hour.”

“Burpee’s ‘Hall of Fame’ was enhanced by… Red and Gold Marigold (1939)…Marigolds were… Burpee’s most popular flower seeds so it is not surprising that a great many of the world’s most outstanding marigold varieties have been developed at Burpee.”
“W. Atlee Burpee had established Floradale Farms at Lompoc, California, in 1909 [in addition to the original farm in Pennsylvania]…The Floradale site was chosen because it was situated in an ideal valley, protected by a mountain range that runs from east to west (rather than the more usual north-to-south orientation). It has what might be called a “European climate,” cool but without great temperature fluctuations, and constantly humid rather than subject to heavy sporadic rains. Indeed, Lompoc remains one of the rare spots for outdoor flower seed production in the world…”
