New here, That picture reminds me of the "Tree saws" my Dad used in the 1950's and 60's on the farm outside Joplin,Mo.The saws he used were built in Joplin by the Hampton Machine Works.They too had cast iron Clinton engines,about 4 to 5 hp.The front mandrel swiveled from horizontal to vertical.The blades were 20" to 24".He would cut all day Saturday and lay down enough trees(red oak,black oak and blackjack oak) to keep the two hired men trimming them into poles busy all week.They trimmed with axes,they were afraid of power equipment.They did that all year round,trimming and piling poles.In the fall and winter he would put the "Buzz Saw" on the Ford 9N and buzz them up into stove wood.The wood was hauled down to the house in a 1936 International dump truck.I was a passenger in the truck while my mother drove and dumped,about 6 or 7 years old then.Over the years,they cleaned up 103 acres of brush and turned it into pasture land.I got to participate around 1965 when my Dad bought a McCulloch 1-43 for me to run while the guys trimmed.Nice saw to start out with at 15yrs. old.(I was 6'3" 175 at the time)I also had a new truck to haul wood in,a 1941 GMC dually,no dump bed.
I enjoy reading about your projects,much prefer to read about the older saws.
