Follow up on my 870 not running.

About a week ago I posted that I was taking a wagon from one farm to another farm & with my 870 gas and it just quit like I turned the key off. Several of you gave me suggestions & what to look for. What I found was a bad rotor. All though it was a little over a year old I put the old one on and its fixed. Thanks to everyone that offered suggestions so I could get it going. Thanks again. Gerald

Glad it was a simple fix

that's an odd thing to happen. i have never heard of a rotor giving up in a tractor. and have seen some pretty worn out ones. G.M. had rotor problems with them black rotors burning through in the 80's with electronic ignition , they then came out with the white rotors.

Glad to hear it was an easy fix. I had a similar problem with my 71 Dodge Charger. One morning it just wouldn't start and when I opened up the distributor cap the new rotor had fallen apart. Can't even trust new parts these days.

If the rotor failed by shorting to ground internally (vs. physically breaking) that can be a sign of a ''bad'' (high internal resistance) sparkplug wire.

Does it have a good set of ''wire core'' wires?

If one or more carbon filament/suppression wires have somehow found their way to your tractor and one has failed internally the ''new'' rotor will also fail, eventually.

The 870 here had a bad rotor. The metal insert that acts as a stiffner where the rotor fits the shaft, shorted thru the bakelite material to the rotor tip to ground it.
