  Power takeoff adapter for drive shaft - Patent 5247845
The power takeoff adapter includes a male pin adapted to be received in a complementary female receptacle in the crankshaft, wherein torque applied during operation initially tightens the coupling between the adapter and the crankshaft.
The power takeoff adapter includes a pin having a tapered portion complementary with the taper in the receptacle and a male threaded portion adapted to be received by the tapped socket of the receptacle.
The power takeoff adapter and crankshaft are designed such that the tapers on the receptacle and the pin absorb all operating loads during use, making the assembly inseparable without distortion such as by heating or the like and rendering the threads unnecessary and nonfunctional during use.

 EH.Net Encyclopedia: Economic History of Tractors in the United States
In the provision of motive power, tractors were a replacement for human effort and that of draft animals, both of which are still used extensively in other parts of the world.
The greatest amount of power was needed for plowing, often forcing farmers to keep one or two extra horses above the number needed for the remainder of the year.
A new source of power, then, would be valuable to the farmer if it could replace the horsepower requirements of plowing, as long as the cost was less than that of maintaining one to two extra horses.

 Page b1 Takeoffs
The rotation used for crosswind takeoffs is somewhat different in that the aircraft is lightly held on the runway with yoke held fully into the wind.
At the moment the aircraft reaches a safe takeoff speed for the existing ground effect the yoke is leveled and the yoke is used to 'hop' the aircraft off the ground while the rudder is used to crab the nose into the wind.
The situation is a takeoff area of unlimited length but having a soft surface the nature of which would prevent acceleration of an aircraft to takeoff speed without the application of special techniques.

PiAC argues that this could be addressed by replacing the aircraft's auxiliary power unit with a supplementary power unit and channeling some of the power generated by the SPU into an upgraded main drive train on an "as-needed" basis in high-demand situations.
The engine powered a 41 foot fully articulated three-bladed rotor and a 5.5 ft three-bladed ducted propeller in the tail (called a "ring-tail") to provide forward thrust and directional and anti-torque control with four vertical vanes in the duct.
After takeoff, power was applied to the pusher propeller for forward propulsion, and in cruising flight the craft's small wings helped off-load the rotor and increase forward speeds.
