Kioti Tractor stalling

[Roger2561]

Hi there. My older brother has a Kioti tractor with FEL, 4X4 that he purchased a little over 2 years ago. It has 74 hours on it. I think he said it has 30hp. He emailed me this morning stating that while operating this past Saturday the tractor simply stalled; he reached down and started it again only for it to stall again a very short time later. He nursed back to the garage where he parked it until he had time to look it over. His F-I-L used the tractor on Monday not knowing of the stalling issue. He used it for a short time (he did not quantify) when it suddenly stalled on him. He was able to nurse it back to the driveway but he was unable to get it into the garage because it would stall everytime he tried to move it. When my brother got home he was able to get it in the garage from the driveway but not until it stalled 3 more times in the 30 feet of travel distance. Any ideas what may be causing the problem? Thanks, Roger

Check and make sure it's not the kill switch. The linkage might be catching.
And of course, try some differant gas.

Sounds like fue delivery.Check/change/clean the fuel filter first. I would also add some Power Svc to the tank.
Btw, see "cracked fuel bowl" post below.......

Not to be a smart *****, but make sure it is diesel fuel not gas. My neighbor's son fueled up his Kubota BX23 and filled it with gas not diesel, he had nothing but problems until he drained the whole thing and cleaned out the filters and lines, but I believe his tractor would not even run to be able to stall.

Gravel13: Believe me, that was my first question to my brother. He laughed at first, then got a little serious and then checked the fuel tank - it's diesel. My brother is going to check all the electrical connections when he gets home from work this evening. It's probably the easiest and most definitely the cheapest thing to do.

Thanks everyone for the suggestions. I hope to keep you posted on the outcome. Roger

Just one more idea ! If for some reason the tank vent is pluged that would also cause stalling . An easy test is to see if it runs with the cap loose !

That's where I put my money ------

Only electrical that would matter on a diesel with regards to stalling would be a fuel solenoid. Gotta be air or fuel, with 74 hours would be shocked if compression unless of course there's a decompression knob pulled open.

Maybe fuel solenoid, if it's got one (my 3054xs does not).

Or could be fuel pump, not sure on that motor if there is an electric fuel pump prior to the high pressure injector or a mechanical pump, either way, that could cause what you're seeing.

Would be surprised to see a filter go clogged so quickly, unless someone put in junk diesel.

My two cents.

Okay - Heard from bro this morning - His Kioti is a CK30 Manual Transmission. Last evening he cleaned the battery posts nice and shiny. After he finished doing that he attempted to start the tractor, it started but stalled as soon as he pressed on the fuel pedal. He said he waited a couple of minutes before trying to start it but this time when he started it, it started but the engine rpm's kept increasing although he was not touching anything. He immediately shut it off to protect it from an over rev condition. He has no clue what to do now other than calling the dealer asking what the heck the problem is. The closest dealer is approx. 60 miles away. If anyone has any other suggestions, we are open to trying them. In the mean time, I'll keep everyone posted when the problem is resolved. Roger

Injector pump?

 

[MotorSeven]

Hmm, over rev-ing. I wonder if the FIL was grubbing. I would check the under carriage closely to see if anything is un-plugged, or that a stick is not jammed against some linkage or wiring.
I was hoping Wallace would jump in here, he is darned good at internet trouble shooting..........

It sounds like a fuel issue....
CK fuel filter first as that is the cheapest thing to do.
Also check fuel for water, dirt, etc....

The engine reving high..... could mean a injector is giving problems.

NY_Kioti_sales: Heard from older bro a few minutes ago and he said the dealer from whom he purchased the tractor believes its the injector pump giving problems. The dealer said he'd do everything he can in his power to get it covered under warranty. Bro asked what may have caused the problem with the injector pump and his answer was moisture in the fuel may have caused pitting causing it to stick closed and then stick open. Does this make sense to you? Do you know of an additive that he can put in the fuel tank once it's running again to prevent future happenings again? Thanks for the help. Roger

Has he pulled the fuel filter yet? Before i started messing with the IP i would definatly check the filter first. A red bottle of Power Service 911 will take care of any water in the tank.

Again, please do things in order. Start with the simple things then progress. Injectors or injection pump should be the last thing to check.

Check your fuel filter! Why would you want to possibly damage a new part if you have bad fuel with water in it?

What you said makes some sense, but I would want to actually check it over before just saying thats the problem on the phone. This can take time and still not solve your issue if you have fuel with water in it.

Whoa... Go easy on him.

I would agree to start slow however he is getting a lot of idea's thown at him and may not know where to start...

Someone want to start a list in order such as (don't use this, it's only an example)

Look in tank (with flashlight) to search for dirt or other items
Check for cracked fuel bowl
Add A red bottle of Power Service 911
Check Fuel Filter
Drain fuel and add new
and on and on...

remember, they are under stress right now.

sorry had to play the other side.

I hate to state the obvious, but I'm thinking 74 hours = dealer fix for free under warranty, otherwise why buy new?

Maybe I'm missing something but I've seen a number of posts with guys trying to fix new machines on their own and I don't understand why?

Lots of smart people on this forum so there must be something I'm missing?

I think the reason some are trying to fix on their own is that is most cases, having warranty work performed by the dealer will take their tractor out of service for days (depending on shop) and most owners will have to provide their own transport (of which some may not have, only adding to the cost).

Now add in the wealth of information from the best tractor troubleshooters on the net, and I have a feeling that some are driven with the thought that if they can fix in a few hours with help from those here, they will be back in the seat much quicker and for much cheaper. IMO

For me, no brainer and I am with you, I would call my dealer and let him know. He will come pick up my tractor and return it at no cost to me. I don't suspect all dealers do this and I am sure it helps only being 4 miles from the shop also.

I am not trying to brag or add insult, and hopefully the experts here will have him back up and running soon. I agree with Joel and would further add that you want to make sure you don't void your warranty by doing something that your not supposed to.

sounds like my tractor with air in the system.

 

[NY_kioti_sales]

Good point rob.
Have you changed your fuel filter already and then this problem started?
If so, you didn't bleed the air correctly.
