WHERE CAN IGET SOMETHING TO CHECK THE SPEED OF THE PTO ON AN H FARMALL? THANKS DON

Andy Motteberg · Aug 8, 2008

An H PTO should run about 540 RPM.

Something like what's below?

I didn't nned a costly one. This one has held up and worked fine for my purposes -- pto speed, small engine RPMs . . .
Inexpensve laser tachometer

You can get a hand held tachometer with drive end that is held to end of pto shaft. Sold at some tool and industrial supply places.

like dave says. get a hand held tachometer. check your local flea markets for a used one. high idle pto speed for a h is 595.

laser tachs are cheap on ebay

Though you can check it, I do not see why if you are just using it. If the tractor goes at the rated speed in gears, Like 16 in fifth at full throttle, it will be fine. The rated speed is just a design idea and equipment spec, not reality. They work in a range from about 600 to 500 RPM all the time. It cannot be higher than that fine range unless the governor has been messed with and it goes faster than 20MPH in High gear. It is not a precision requirement. They did not make 1000RPM shafts in those years, so no risk of that. JimN

Stewart Warner makes a hand held RPM instrument that measures RPM by holding it to the end of a shaft. It shows left or right movement.
