This is one of a pair of
John Deere Sulky Plows out front of the museum. Both two bottom plows, the major difference between the two is that this plow is a real two bottom plow, allowing plowing in only one direction. As well, it has coulters for each share whereas the other doesn't.
The museum is on Round Butte Road at the corner of 6th Avenue NW. on the west edge of the town of Ronan, MT.
