ashtonosborne2019 18 #1 Posted April 13, 2021 today my wh 520-h would drive up the drive way like 20 ft and just shut off and not start it will idle but when i drive it for a bit it shuts off maybe spark plug coil or starter solenoid or ignition switch.

lynnmor 6,780 #3 Posted April 13, 2021 Bad fuel pump or the screen in the tank outlet is clogged. Just a guess, give additional performance history and maybe we can narrow it down. Share this post Link to post Share on other sites

Just a guess, give additional performance history and maybe we can narrow it down. i switched the pump yesterday and the tank outlet might be clogged. the tractor has great performance history and it will only get 1 spark every half a minute and that is what leads me to think why the spark plug coil or the stator.

I had a similar issue with my 520, mine turned out to be a corroded fuse block. The fuse for the ignition would loose contact momentarily. Diagnosed this when I noticed some of the gauges cutting out at the same time I lost spark. Share this post Link to post Share on other sites
