May 1, 2012 / JD 5420 tachometer issue #1 S sndy New member Joined May 1, 2012 Messages 1 Location Canton, Oh Tractor JD 5420 I have a JD 5420 and the tachometer isn't working right. Sometimes it won't work at all and other times it will bounce up and down. Is this just a loose wire? a sensor? There is no cable.

It may be the speed sensor, part no. RE519144 But then it may be a loose wire going to that sensor. jdparts will show you where that sensor is located, if you can't find it.
