Problem with a new Kubota 2370

[bandit99]

I have a new one that only has 13 hrs on it. When I start it during cold weather it races at 3000 rpm for about 30 seconds and then quits. After that it is hard to start again. Doesn't seem it would be good to have it at that RPM cold. Once I get it running again it seems to run fine. Haven't been real pleased with it so far.
Throttle position makes no difference.

Don't know how far away your dealer is but I'd take it back to have him fix the problem.

Have you treated your fuel?Powerservice or Howes?

now is the time for the dealer to get the bugs out while Warranty is still in effect.

Agree. This is precisely what a warranty is all about. You didn't say whether you've made your dealer aware of the issue. That's your first phone call. Hope it works out simply and quickly.

Plan on contacting dealer Monday, but was hoping there was something simple that could be pointed out to me. Dealer hasn't been real good so far. Delivered tractor and installed snowblower on front. Hammered the shaft on to the rear PTO. It was cold, said probably ice on it. When came time for me to remove front mount blower I couldn't get it off. They came and got it, said it was a burr. While there I had them install block heater. overcharged my credit card $44 from what they quoted me on phone to charge my credit card. I guess I better take it up (40 Miles) and have a talk with the dealership owner and let him know that so far I'm not real happy!

Have you treated your fuel with any additives for cold weather? And, have you purged the fuel line? In in extremely cold weather fuel gelling can be a real issue.

I have a new one that only has 13 hrs on it. When I start it during cold weather it races at 3000 rpm for about 30 seconds and then quits.

The only reason the rpm would go to 3,000 rpm would be excess fuel provided to the injectors even with the throttle arm in the retarded position. Take a deep breath and push the dealer to get it right.

In Maine the diesel is cold weather treated at the pump I believe. Today was nice and sunny and 27 degrees, Tractor sitting in the sun and it did the same thing. Never had this pproblem with my BX2200 in 8 yrs. We'll see what the dealer says Monday. Was hoping someone would say something like" Oh, that's easy, just turn the cuniffiler pin to the right and it will cure the problem". No such luck. Want to get it squared away before something breaks or I do damage that will show up after the warranty period. Thanks for the responses.

Are you sure the throttle is set at idle or is it set a fill throttle?

 

[bandit99]

Throttle is set at idle and does not change RPM even if you move it through the full length of travel. Just quits after racing at 3000 rpm for about 30 seconds. Can't slow it down w/o turning off key.

When you move the throttle lever,are you sure the linkage is moving on the engine?Sometimes the locknut on the throttle lever will come loose and the throttle doesn't operate correctly.Something to check for.

A great rule of thumb-
Never trust anyone else to treat your fuel, fuel station or otherwise. Hope you get the bug worked out soon and to your liking. Nothing sucks more than problems with a new machine.

I also have a Kubota BX2370 with 123 hrs. that just started to do the same thing. I do use a commercial fuel additive. Last winter I had know problems even starting at 10 below zero. I tried to shut it off when it got over 3500 rpm, and it kept running with the ignition off, for over a minute. The exhaust turned a grey color when it do this, not black or blue. I let it cool down for the day, and started it without using the glow plugs and it started with no problems at 18 degrees. It seems to do it if I use the glow plugs. Any suggestions?

Guys, this doesn't sound good. Racing a cold engine like that is BAD, as you probably know. And a dealer that abuses customers is bad, too. Sorry to hear about this, and hope you get good outcomes. I would contact Kubota, just to get on record with them in case you have engine problems later (assuming this gets fixed!) caused by high speed cold running.

I was thinking the same thing, linkage is screwed up somewhere.
You pretty well have to be a mechanic now days when you buy a tractor.
Bandit, How did this turn out for you?

This sounds like a problem in the injection pump rather than linkage,I would sure get the dealer involved right away and document everything for future protection. This is a great way to score a cylinder wall or worse.

I talked with my Kubota dealers service today, and he said he has herd of the problem, mainly in colder climates, but at the time don't know a solution. He said it might be from a ice build-up in the fuel regulator. I had it documented with my tractor serial numbers and if anything comes in from Kubota about it, he will contact me.

Last week-end I forgot to cover up my Kubota 2370, and didn't fold the set forward, and we had about 3 inches of rain that night (May 30th)
I went to use it today and the instrument cluster has about 1 inch of water in it. With the sun shinning on it, it completely fogged up unable to see anything. Question? How do you get the water out of it, and has anyone else herd of this problem before?

Try removing the wire mesh underneath the steering wheel, you will see the battery there, look up underneath where the throttle is and pull the throttle in and out to see if the linkage there is connected and operating correctly.
