The other part of the diet is daily drops or injections of the pregnancy hormone hCG, which supposedly accelerates weight loss by suppressing appetite and blasting fat.
Power take-off. A power take-off or power takeoff (PTO) is any of several methods for taking power from a power source, such as a running engine, and transmitting it to an application such as an attached implement or separate machines.
I still use 3 elevators to get hay to various places. 2 are PTO driven and I have a short (14' or so) one that is electric. The electric one is driven by a 1 hoss-pressure 1750 RPM 120V electric motor. The reduction is via sprockets, chains, and jack-shafts. I speculate that the speed of each elevator is @ 20 FPM.
