Garden Tractor Info

This is a recent dialog we had with a John Deere 317 garden tractor owner about starting problems he was having. We like working on the 317’s here at our shop, they are a nice sturdy older ” vintage” tractor.

Q: I have a question about my John Deere 317.

I replaced the ignition switch as it was getting harder to turn to the “start” position. I used an authentic JD part, so I know the new switch is fine, but now I don’t get any click (or start) when I turn the new ignition switch to start. The battery is fully charged and the PTO switch relay clicks when I turn it on. I have looked and can’t find that I pulled a wire loose when I traded ignition switches. There is also no draw on the battery when I turn the ignition.

Is there any troubleshooting steps I could take to figure this out?

A: When you go to start mode the electricity has to go through your neutral safety switch, check that switch and wiring. Then from there it goes to your PTO switch where the problem could be loose connections, corrosion at the connectors, or a bad PTO switch and yes, I realize you said it goes click when you move the PTO switch up and down. The PTO switch is actually two switches in one so, in other words, the PTO switch can still be bad.

Q: Jim, when you say Neutral safety switch, you mean the one for the hydrostatic transmission?

A: Yes, that neutral safety switch is located below the neutral groove in the dash.

Q: Jim, that did the trick. I took the plugs off each switch, wire brushed them and I’m back in business.

One more question about the starter on the JD 317. With more and more frequency, my starter sounds like it doesn’t engage. When I turn to the start position on the ignition, I get what sounds like a low growl (and it sucks the battery juice down). After several tries, it will usually kick in. Would you guess the starter needs rebuilt, or just lubricated? I have an old enginefrom this tractor. I looked at the starter and see that the gear slides out on the starter motor shaft to lock into the flywheel. It was rusty of course, but thought I might try just lubricating the shaft on the tractor before replacing it. I am considering getting the other starter rebuilt and switching them.

A: Yes, it sounds like the Bendix drive is sticking on the spiral spline on the shaft of your starter. Spray carburetor cleaner and rinse it out. You can do this without pulling the engine.

Q: Jim,I think I told you that following your directions, everything worked out well. What I did notice though, is that it looks like I need to pull the engine if I were to replace the starter. Is that correct? I looked all around and under the tractor, but doesn’t look like there’s any way to get the starter out without at least loosening the motor mounts on the one side and tilting the engine. Is that so? I just want to prepare myself for that day.

A: You are correct, you have to pull the engine in order to get to the starter. You can just lift the engine up a ways, not remove it, but it is nice to take it out and pressure wash everything.

I think everyone knows I really like John Deere lawn and garden equipment. If you have a good quality machine it’s worth fixing her up! Yes, I know there are other brands that are good quality, but these questions are just about John Deere’s.

Q: I was wondering how I would know if I have a bad cam or bad intake valves on a John Deere 445 garden with a 22HP Kawasaki engine.

A: We do not get bad camshafts on the 425-445 garden tractors but what happens on the camshafts is that the cam gear is made from nylon and typically at about 800 hours the gear teeth will break of. When that happens the engine will shut down and will not start again until a new camshaft is installed as the gear is casted to the camshaft. The replacement camshaft is all iron, therefore no more problems.

Q: I have a John Deere 111 Lawn Tractor which won’t start. I suspect a fuel problem. When I take the hose off the fuel pump (Autopulse) and crank the engine, I don’t get any fuel but if I take the feedline off and lower it towards the ground it drips gas.

My questions are:

Does this suggest the fuel pump (or does the hose have to be connected to the carb to
pump)?

If so, are there any other options for a replacement given that we don’t have a John Deere dealer at the moment?

A: It does sound like you have a bad fuel pump. When you lowered the hose coming from the tank, the gas should have been coming out at a slow flo. If it was just dripping you might have a partly plugged gas line or gas tank problem. If you want to buy a fuel pump I have them in stock.

Q: I have a John Deere 318 garden tractor and I believe the starter went out of it. How do I remove the Starter, as it appears that there is no room or easy access to do it. I enjoy your site as you explain it in layman terms.

A: You have to remove the engine before you can take the starter out. On some of those Onan engines you will also have to remove the engine fan shroud to get at one of the starter bolts. It gets to be a fair sized job to get it all done. Glad you like our site, thanks.
