John Deere 40

The John Deere 40 was produced from 1953 to 1955 as a utility tractor built in Dubuque, Iowa, USA. It replaced the John Deere M model. The 40 series included several variants such as the 40S standard, utility, high-crop, 2-row utility, and a crawler model (40C). The 40C and utility variants were also used as industrial models though there was no official industrial designation. The tractor featured a 1.6L 2-cylinder engine available in gasoline and all-fuel versions, a 4-speed gear transmission, and two-wheel drive with manual steering. It had an open operator station and a rear type I hitch. The PTO was transmission-driven with a 540 rpm rear PTO type. The tractor weighed between 2900 and 3220 pounds depending on the variant and had various tire options for front and rear. Attachments included loaders such as the John Deere 30 and 40 loaders with specified lift and breakout capacities.
