"Power tiller of a hundred uses"

FM Type J Engine

20" tires

"Use the same power tiller that prepares seed beds in one operation, for cultivating. It pays off in time and work saved and more efficient results. For you can adjust tilling depth just as shallow as you like, even a fraction of an inch. The high speed rotary action works every inch of cultivating width. Weed and moisture control are so effective that cultivation is required far less frequently than usual."    A Rototiller ad
