The Cockshutt 550 row-crop tractor was built by the Cockshutt Plow Company, from 1958 to 1961. It succeeded the Cockshutt 35 Golden Arrow in the Cockshutt product line, and was capable of pulling two or three plows. The new tractor was restyled in accordance with the trend toward squared-off lines, compared to earlier Cockshutt offerings. Confusingly, the 550 was replaced in 1962 by a different Oliver-built tractor, also branded as the Cockshutt 550.
Description and production
The Cockshutt 550 succeeded the Cockshutt 35 Golden Arrow as a medium-sized row-crop tractor. In accordance with industry trends of the early 1960s, the 550 was styled with squared-off lines by industrial designer Raymond Loewy. The 550 was powered by a Hercules Engine Company {{convert|198|cuin|cc|adj=on}} four-cylinder gasoline engine with a six-speed transmission. A Hercules diesel engine was optional. The three-point hitch incorporated hydraulic depth and draft control that had been introduced in the Golden Arrow demonstrators. The 550 could be ordered with adjustable wide front wheels, narrow wheels and fixed wide front wheels{{cite book |editor1-last=Miller |editor1-first=Melissa Carpenter |title=Cockshutt: The Complete Story |date=1999 |publisher=American Society of Agricultural Engineers |isbn=1-892769-07-7 |pages=65-66}}{{cite web |title=Cockshutt 550 |url=https://www.tractordata.com/farm-tractors/000/6/6/660-cockshutt-550.html |website=TractorData |access-date=20 March 2022}}{{cite book |last1=Pripps |first1=Robert N. |title=The Field Guide to Classic Farm Tractors |date=2020 |publisher=Motor Books |isbn=978-0-7603-6844-2|page= 192}}{{cite book |last1=Swinford |first1=Norm |title=The Proud Heritage of AGCO Tractors |date=1999 |publisher=American Society of Agricultural Engineers |isbn=1-892769-08-5 |page=134}}
