A realistic conversation with a Reg. Patent Agent or Patent Attorney is 
what you need. You no doubt have a fund of ideas, many of which you 
haven't described here; and that contact will be necessary. Don't plan 
on selling any inventions without a patent; businessmen can only buy 
what has a legal instrument of property. The patent identifies and 
creates objective intellectual property out of the inventive concept. 
Also, join an inventors club for information and networking. Don't go to 
any organization which receives its sales revenues from the inventors.

Regarding the electric motor on a tractor . . . .  .  . . ....  .. 
That was the topic of a hilariously funny cartoon in the automotive 
press during the 1950s - possibly, Hot Rod Magazine. A dragster was 
shown at the starting line of a drag race with speed and wheels 
spinning, only it had a big electric motor instead of a gasoline engine, 
and it had a power cord and a big electrical plug.

Maximum torque and horsepower at low RPMs are just what are needed for 
maximum acceleration. The electric motor is perfect for farm tractors. 
Higher voltages and alternating current may, on advice of an electrical 
engineer, provide less power transmission losses.

The notion of auto engines being called 'motors' by the racers seemed to 
stick, and NASCAR racers today mostly call their car engines 'motors'. 
Its a fa****onable joke. The term seems to be more popular in the US 
South. Weirdly, however, NASA bucks the trend and incorrectly calls 
rocket motors 'engines.' 'Engines' is the proper term for both confined 
expanding steam and  [Otto Cycle] internal combustion mechanical or 
reciprocating engines and jet engines, however. 'Motors' is proper for 
rocket motors and electric motors, which have no machinery.

Good luck with your inventing.
