These machines were built from December 24, 1934 until March 19,
1937 and were imported by Rototiller, Inc. There were 768 units
built. The tiller had 2 speeds forward and developed 6 hp @ 2800
rpm. There is a video of it in action at my YouTube

I sold this machine toward the end of 2014 to make room for another B1-6.
