What is a PTO generator?
Farm tractors and some trucks and industrial engines can have a
PTO or Power-Take-Off shaft that is used to power attachments such
as sprayers, hydraulic pumps and, well, generators. The PTO is low
speed, so a PTO generator usually has a gearbox to step the speed
up to the RPM needed to turn a generator. PTO's are pretty
standardized and use a short driveshaft to couple the tractors PTO
to the attachment. PTO generators are used where remote power is
needed and a PTO-equipped vehicle is available. It saves having to
buy and maintain another engine.
