Patent ID: 8210071

Claim:
A fluid drive system for coupling an input drive shaft receiving rotational power from a power take-off (“PTO”) unit, the PTO unit operatively coupled to an engine disposed in a motor vehicle, to an output drive shaft for operating a vertical feed mixing tub, the fluid drive system comprising: a) an input gearbox having an input and an output, the input capable of operatively coupling to the input drive shaft, the input gearbox configured whereby the output rotates faster than the input, the input drive shaft configured for operatively coupling to the PTO unit; b) a fluid coupler having an input and an output, the coupler input operatively coupled to the output of the input gearbox; c) a flex coupler disposed between the output of the input gearbox and the input of the fluid coupler; and d) an output gearbox having an input and an output, the input operatively coupled to the fluid coupler output, the output gearbox configured whereby the output rotates slower than the input, the output of the output gearbox capable of operatively coupling to the output drive shaft, the output drive shaft configured for operatively coupling to the vertical feed mixing tub.
