Tractor
Kioti NX5510
Hello, we have a 2021 NX5510 with 50 hours on it, I used it 2 days ago, everything was fine, started right up, etc.
I go to use it yesterday, and it will not start. Its in neutral, brake is fully depressed, PTO is off, Im sitting in the seat, Battery is not dead, I hook it up to some jumper cables to our running truck just in case, no change. I can hear something click under the hood when we turn the key to start, it sounds like one of the relays up top near the front of the hood. I tap on the starter with a hammer while my wife tries to start it, that doesnt help. We give up for the day and decide to call the place where we bought it from to see if the warranty covers what ever is going on.

We call the dealer, they say its not covered, it would be $140 a hour to check it out, $75 service fee, etc.. that sucks...

So I go out today to check the fuses after reading on here a bit, figure why not try to start it again. And it starts right up. No changes from yesterday at all.

Anyone know what part this would be then? I really want to not have this happen again when I need the tractor the most.

I've had loose battery cables act that way in the past. One of them was the connection at the starter. I didn't even feel the nut get tighter when I tried it but it made all the difference.

Thanks, I'll try that!

If you keep clicking does it eventually start? If it does it might be the click-click-start problem that plagues several different brands.


If that is the problem it can be easily fixed by adding a relay.

Hope this helps.

I must have tried about 30-40 times yesterday and it never started, so I would guess probably not? But thanks for mentioning!

More than likely battery cable issues. If you can grip the connection on the battery and twist it…its too loose.

I agree with the battery cable connection recommendations, but will add that you should remove / clean / reconnect all high amperage cables including the starter connections and chassis ground.
If the problem continues, consider the starter relay modification that was mentioned in a post above. There's no downside to adding a starter relay, and really all starting systems should be designed that way. I have them on both of my diesel zero turns.

I cannot believe that a 2021 tractor with only 50 hours isn’t under warranty.

It has the powertrain warranty but bumper to bumper was out in november. I personally dont see how this is not powertrain related since it wouldn't start, but apparently it is not.

Well it happened again today, would not start. So I cleaned up all the connections at the battery and the starter, and tightened everything really good. Tractor still would not start. I tried another 10x, nothing, I can still hear a relay click from under the hood when I turn the key to start it.
Im not sure why I tried this but I decided to hold the key in the start position one time, and after about 5 seconds the tractor started right up.
I go to move it, turn it off, about 10 minutes later I go to start it again, will not start! I tried holding the key again like last time, nothing! I try for even longer, multiple times, Refuses to start!
This is pissing me off as the tractor is literally like new, what part could this be?

Just to rule out a failing relay, find the one clicking and swap it with another. I know it clicks, but doesn't mean its actually good.

Also, trace the wires out. 50hrs in 3yrs is not a lot of time and maybe a rodent or 2 had fun in there.

If this is an open station machine, perhaps the key switch has gone bad. i remember lost of issues on open station key switches over the years. Rain and such take their toll

Squirt some wd40 in the key slot and work it back a forth worked for me once, worth a try .

I found a old post from someone else that had the same problem and they mentioned running a ground from the starter relay on a different model kioti that fixed the problem. I was able to find which relay was the starter one, ran a wire from the battery neg. terminal to one of the ground terminals on the relay and it started right up. Tried it about 5x, starts right up everytime. Alright! At least I can use my tractor now!
But, Im still wondering what part does that mean is bad then?

Safety switch in the seat. Unplug it and put a jumper across the wire connection on the harness.

That was my first thoughts too, first thing I tried when this started, but didnt do anything

Check all of the switches. I had an issue with my tractor when it was not on level ground. My neutral safety switch would keep the tractor from running/starting when I was on a hill. The position of the switch would allow the weight of the lever push against the switch and close it the same way it would if I was in gear. I needed to adjust the position of the switch.
