gwest_ca-(File Mod) 11,393 #2 Posted May 28, 2020 Welcome to the forum. When the pto is engaged the seat switch powers the ignition. I suspect wear in the seat hardware or switch mounting is allowing the switch to open. If it is a button switch try adding a few layers of rag or something soft to tighten up the button clearance to see if it eliminates the problem. Some switches have a threaded mount that can be adjusted. Garry Share this post Link to post Share on other sites
D_Mac 9,299 #3 Posted May 28, 2020 Welcome to Red Square ! When it sputters are you traveling up hill ? If so it may be a fuel pump issue. I am not the best to ask but more qualified folks here will be able to better diagnose the problem. Share this post Link to post Share on other sites

953 nut 59,310 #5 Posted May 28, 2020 Depending on the year of your 416 the seat switch may be inside the seat foam padding (1992 and newer I think). If the seat is not in good condition the switch can become a bit touchy, had that problem but a new seat cured it. Part # 23 in this drawing. Share this post Link to post Share on other sites
Lee1977 7,144 #6 Posted May 28, 2020 My 1989 520 did that if the ground was a little rough. It still had the seat switch down on the seat pan, but the plastic button on the seat switch was almost worn down to nothing. New seat switch fix that. Share this post Link to post Share on other sites
Ike 75 #7 Posted May 28, 2020 I had the same maddening problem with my 314-h. It was the seat switch. Share this post Link to post Share on other sites
