#2574 Bicidesgranadora (Mill/Corn Thresher)


This bicycle machine is adapted to fit a hand-powered grinding mill or a corn thresher. The mill function has the capacity to mill pounds per minute of any type of grain. The most common use is for milling yellow maize, soya beans, and coffee.

The thresher is used post-harvest and easily degrains 12 to 15 quintals (1 quintal = 100lbs.) per day and requires only one person to operate the machine.
