Let's be positive now, it took me a while to find this little rascal.
Besides, it will look so much better on your instrument panel than a drawing of a Tach. LOL
I have a Sears DGT 6000 w/Kohler 27hp Command and it has a little electric Tach, but I haven't quite been able to figure out how it works unless it picks up off of the magnito/flywheel.
Anyway, since this one says Diesel on the face it looks a little more official.
But, OUCH, the $114.95 and then there's shipping.
However, what I would suggest before making a purchase is to print out the .pdf file

(or perhaps Sears) and see if they have the electronics to set the calibration .
I remember the salesman telling me to push the throttle forward as far as it would go then bump it back just a bit and that should put you right in the RPM range you should be for the hydraulics and PTO to work right. he he he.
