drn441 11 #1 Posted July 31, 2018 I just acquired a 417a.. As it sits it has 1500ish hours on it and does not run.. I haven't had a whole lot of time to mess with it yet but i would just like to get it started to see if it runs and if its worth putting more time and money into.. so far i can say it is getting fuel but no spark.. i noticed the seat safety switch has the wires cut and wire nutted together.. it has oil and cranks well with a jump pack.. Does anyone know if there are any other interlocks to prevent it from starting.. Also as far as wheel horse tractors go is this a decent model? 2 Share this post Link to post Share on other sites
pfrederi 17,203 #2 Posted July 31, 2018 Series 2 engines are good. See if you have 12 volts at the coil Share this post Link to post Share on other sites
953 nut 52,355 #3 Posted July 31, 2018 You have a series two KT-17 which is a good thing, they ate much better than the earlier ones. Have you cleaned the points or checked for spark at the plugs with a 12 volt jumper to the "+" side of the coil? Share this post Link to post Share on other sites
The Gman 476 #4 Posted August 1, 2018 Also....... check the oil pressure sensor switch. It's a normally closed switch (grounds out ignition). When pressure develops it opens. Share this post Link to post Share on other sites

When pressure develops it opens. You made me go look but I don't think this is the case. On the 417 and 420 the engine oil switch controls the oil light only. The 417 uses battery ignition and the 420 uses magneto ignition so the pto switches are wired differently but that is all I see. The twin cylinder Kohler models did not get the low oil switch that prevents the starter from working. This is from the 1986 tractor operator manual.

The Gman 476 #6 Posted August 1, 2018 Hmmmmm, Mine was modified at some point then. It was wired into the coil's circuit. Maybe because the circuit board was trashed. It took about 5 or 6 cranks to start. Since put a pressure gage into it. Share this post Link to post Share on other sites
drn441 11 #7 Posted August 2, 2018 I got it fired up. It ended up being a combination of corroded points and bad gas.. I ran it out of a bottle so I'm going to drain and clean the tank and go from there. Thanks 1 Share this post Link to post Share on other sites
