Rotary Tillers w/ Vertical Shaft Engines
Does anyone remember all of those rotary tillers (or "roto-tillers," "Roto-Spaders," etc.) which use the vertical-shaft engines? This classification of tillers seems to have died in the late 1970s, as most of the powered rotary tillers used horizontal crankshaft engines (even though there is at least one MTD tiller made in recent years that has this setup).
As a result, Tecumseh stopped making roto-tiller specification vertical-shaft engines (service numbers being 8036XX, 8046XX, 8056XX, 8066XX, etc.) except the 2-cycle minis (TC200 and TC300 with service numbers like 8006XX), although on the Briggs & Stratton side, you could still get replacement V-shaft engines provided you have all the necessary parts to add and/or remove so the newer engine meets the same requirements as the original.
What do you think of roto-tillers with the vertical shaft engines and comparing those with the tillers that bear the more common horizontal shaft engine placement?
