Cultivator

A rototiller-cultivator apparatus comprising a body portion, an engine mounted in said body portion, a transmission housing mounted on a bottom of said engine and extending vertically downward from said engine, a transmission shaft extending vertically downward from said engine through said transmission housing, said transmission shaft being coupled at its upper end to a crankshaft of said engine and mounted adjacent its lower end for rotation about a substantially vertical axis in said transmission housing, a cultivator tine shaft extending horizontally and laterally through the lower portion of said transmission housing, intermeshing gear means mounted on the lower end of said transmission shaft and on said cultivator tine shaft for driving said cultivator tine shaft when said transmission shaft is driven by said engine, cultivator tines mounted on opposite ends of said cultivator tine shaft for rotation with said cultivator tine shaft when said cultivator tine shaft is driven by said transmission shaft, a power take-off shaft mounted in the lower portion of said transmission housing transversely to said cultivator tine shaft and extending forwardly of said transmission housing with an output end of the power take-off shaft being protruded out of the housing, gear means mounted on said power take-off shaft and intermeshing with said gear means mounted on the lower end of said transmission shaft for driving said power take-off shaft when said transmission shaft is driven by said engine, and a wheel unit for mounting on said lower portion of said transmission housing for direct interconnection with the output end of said power take-off shaft when said apparatus is used as a cultivator, said wheel unit including a casing mounted on said lower portion of said transmission housing over the output end of said power take-off shaft and extending forwardly therefrom transversely to said cultivator tine shaft, a wheel drive transmission shaft having an input end and an output end and coupled at the input end to said power take-off shaft and extending forwardly through said casing, a wheel axle extending horizontally and laterally through a forward portion of said casing adjacent the output end of said wheel drive transmission shaft, running wheels mounted on opposite ends of said axle for rotation therewith and intermeshing gear means mounted on the output end of said wheel drive transmission shaft and said axle for driving said axle and said wheels when said transmission shaft is driven by said engine and drives said cultivator tine shaft and tines, said power take-off shaft and said wheel drive transmission shaft, wherein when said wheel unit is detached from the transmission housing, said apparatus is used as a rototiller.
