[Farmall] Tachometer

[Jeff Dahlke]

I don't know if this is what you guys' are looking for or not. I bought a
digital photo tachometer this summer from harbor freight. You put a piece of
reflective tape on a rotating object and it reads the RPM off of that. It
worked real well for checking the RPM's on our Case 500 diesel. It's not as
robust as the one we use at work for checking shaft speed on our ships we
build, but I compared  the harbor freight one to the better one and it read
the same.
    I paid $59.99 for it on sale but it still lists it at 69.99. The item #
is 41727-1VGA. Hope this helps.
