Kioti Dk50se hst
Here I am operating My new Dk 50 with 30 hrs and yesterday it started blowing a little blue smoke. Today it blows smoke like a chimney, especially at 2500 rpms. It got worse and I am so far very disappointed with this tractor. I know blue smoke is oil. This is not a good sign. I am going to call the dealer first thing tomorrow. Any ideas on this one?

Yes that is not good BUT, this could happen w/ any brand no matter what color. It's a machine, anything can happen no matter the brand. I understand your disappointment but things happen, don't blame the tractor. That's what warranties are for. Hopefully it will be something minimal. Be nice to the dealer when you call him.

Check your engine oil to see if it is over full. if so, check the hydraulic fluid to see if it is low. If so, and you have rear remote on this tractor, see if the lever is locked in either A or B position. If it was, gear pump at back of the injection pump has blown the seal and pumping hydraulic fluid into engine.

Lever is in the neutral position. I just got the tractor back on Fri for a warranty replacement on the hyd pump (it was dripping). Not sure if this is related to the blue smoke. Oil levels check good.

This could be an expensive repair. The good news is this happened while you are still under warranty. The bad news is your machine will be unavailable for a time plus all the hassle. I urge you to start maintaining records on the issue because several initial "fixes" may not get the real problem. Take photos and/or videos. Keep copies of all paperwork. Write and keep memos to yourself documenting all oral communications with your dealer and/or Kioti US. Put the date on everything.

It's possible that this problem is something as simple as bad fuel, a plugged filter, or a dirty fuel injector. On the other hand, it could require a complete engine rebuild or replacement; that's pretty major.

It stinks that you apparently got a bad machine but (as was mentioned above) this can and does happen with all brands to some degree. The measure of a quality operation is how they deal with the problem. For your part, try to remain professional (but persistent and determined) in all your dealings with dealers and/or Kioti.

Don't let all the Kioti "problems" on TBN convince you that Kioti tractors are crap. In general, Kioti owners have less access to dealers (compared to Deere, Kubota, Mahindra, etc.) so they are more likely to use Google, and find TBN, and discuss their problems here.

I dropped it off at 10 am. Emailed a video initially. The mechanic came out and said it smells like fuel. He said it could be bad fuel or maybe an injector problem. The fuel I have been using has come from the same 55 gal drum. I also use PRI D in all my diesel. Fuel should not be it but you never know. He is going to sample the fuel and then go further if need be.

Ritcheyvs said it correctly. And it could very well be a fuel issue.

Hopefully you were using some type of diesel fuel additives in that 55 gallon drum?If not and it,s a contaminated fuel issue it could get costly on your part.Good luck hope it works out well for you.
