Never heard of such a thing. Have a picture or part number? Doesn't it have a proof meter (combo tach, speed and hours)?

Appears there is a part no. RE17515 called a vacuum sensor noted in jdparts for the 2840.

I believe that the 2840 had a cable driven tachometer, and was driven by the camshaft (ref p/n T20071 for a pc pic)

Could be wrong... but I believe the sensor you are referring to is for the air filter.
thanks everybody ...
the local JD dealer said that is what it is (vacuum hour gauge) ...
it does have a mech tach which is connected and it does turn from the cam but the hour gauge is not working ...
i did find the vacuum port and it is now connected but a flat tire is keeping me from driving it at the moment ...

oops, your first post said hour meter... and for some reason my brain turned that into tachometer.

It's an easy fix, get a simple electrical hour meter from any parts house and wire it in to the keyed side of switch or any area you like that has juice when running.
