Rotor tiller having counter-rotating twin shafts |
摘要 |
A rotor tiller having a counter-rotating twin shaft system and counter-rotating digging means such as tines, paddles, or blades for efficient tilling of soil. In another embodiment, the tines on the twin shafts can be replaced by counter-rotating helical auger blades for removal of loose soil or snow. Furthermore, digging bits of suitable kind and size can be affixed to the helical auger blades for simultaneous digging/tilling and removing of soil, snow. This new design eliminates many problems associated with conventional tillers and increases the utility of the subject tiller.
