Branson Tachs, electrical or mechanical?

[Ace Ford]

Anybody know off the top of your head if a Branson 2810 is electrical for the tach? I'm assuming so but don't have my manual (or tractor) handy.

I believe they are mechanical.

My 2004, 3520 is mechanical.

The Branson 2810 is a mechanical Tach. it is driven thru the camshaft, the change to digital came along with the I series
