    Sounds like there is an easy answer so this is probably more than you want to do. But FWIW you might be able to add a factory mechanical tach. The 755 also uses the 3TNA72 engine. The drawings show the 455 has a cover plate where the tach gearbox attaches on the 755. The gearbox along with the cable and tach could probably be added to the 455. This would be more expensive than the Tiny-Tach. Those three parts add up to about $175. The tach alone is $100 dollars of that total.

    HI....Yes that looks like a possibility. The tiny tach is a nice tidy package for about $100 and I'd guess 1-2 hours labor. (I'm a slow worker). Thanks for the info. I'm also investigating a heater for the cab.
    Thanks.....Casey

    On the JD 455 Yanmar diesel, would the transducer be mounted to one of the three fuel lines after the injector pump?
