English: John Deere model LA tractor mowing a Windham, Maine pasture. Tractor was built in 1942 to replace a team of horses. The two-cylinder engine was originally crank started, but has been fitted with an electric starter with the battery box visible under the exhaust. The sickle bar is mounted forward of the rear wheels, and equipped with a covering shield to prevent damage by the over-riding wheel if the bar transitions to a trailing configuration upon encountering unsafe resistance to forward motion. The tractor came equipped with a single 14-inch steel plow blade.
