Garden Tractor Buzz Saw
Don Hermanson would rather take the saw to the woods than carry the wood to the saw. That's why he converted his stationary buzz saw to a portable one that fits on the front end of his 10-hp Case garden tractor.
The Yorkton, Saskatchewan man used the mounting bracket from a snowblower as a base for his saw. He welded two 1 1/2 by 6-in. channel irons to the bracket as upright supports to hold the saw at a comfortable working height. A third piece of 6-in. channel iron was welded to the top of the uprights to support the saw mandrel/drive shaft. The only change he made to the mandrel was to replace a flat pulley with a V pulley.
At the base of the unit, he mounted a jack shaft made by cutting down a drive shaft from a self propelled swather header. A belt with a spring loaded tightener brings power from the engine to the jack shaft and then to the saw mandrel.
"The jack shaft reduces the speed from 3,500 rpm's at the tractor to about 1,800 at the saw," says Hermanson.
An angle iron brace runs from the outside pulley on the jack shaft to one of the upright channel irons. It serves to support the shaft and allows for quick adjustment in tension or for belt replacement.
The saw table itself consists of two 2 by 3-in. angle irons welded together with spacers to form a slot for the circle saw blade and support for wood being sawn. The table is welded to the mandrel support. An angle iron welded to the snow blower framework extends forward and up to support the front end of the saw table.
Hermanson normally cuts up 3-4 cords of wood each winter with his portable saw. "Last year, I was able to take this saw out into the bush to cut the wood up," he says. "It is so maneuverable. Just back it on the truck and away you go."
When he isn't sawing wood, Hermanson uses the garden tractor to grade his driveway. His mini-grader attaches to a mower frame that mounts on the belly of the tractor.
