IH had considered the concept of electric PTO from the '20s. In 1930 they built a prototytpe 10-20 with a front mounted generator. It was coupled to the front of the crankshaft. It was located ahead of the radiator. The capacity was around 10-15 KW. There is a photo in "150 years of IH" written by C.H. Wendel.

The concept became a reality in 1954 when IH built tractors with IPTO. The Electrall appeared during the summer on a few of the last SMTAs. Power is derived from the IPTO gear and runs through a special Electrall gearbox and v-belt to a General Electric 13KW generator. The availability of the Electrall continued until the end of 560 models. There are several pictures in the Photo Section of this site. Search for Wardner or Electrall.

Switchable PTO seems to be redundant after IPTO was offered. IH only sold 103 of these mounted generators. The company eventually got rid of their stock by selling them as rear driven PTO generators. They were mounted on Fast Hitches or trailers. Some were sent to the Truck Division and driven off the transmission PTO.

I have one that was sold with F400 #519. It works fine and I occasionally use it. I prefer to disconnect the belt when it is not being run. Only takes a minute to reconnect. I suspect the original owner left it connected full time.
