Kubota L3301 won't throttle down

[Mr Natural]

The tractor has about 375 hours on it and never had a problem till this. It will throttle up, so I don't think it's the cable, but won't idle down past about 2000 rpm. No regen icon flashing.

What do you suppose is up with that ?

Are you getting any error messages?

If it's a manual cable vs electronic, even at those hours it can be a gummed up cable. Mine had many more hours, but it happened once.

If it ends up not being the cable or linkage, perhaps it's related to the higher rpms required for regeneration. I know the Regen lights are not on, but perhaps the computer is calling for 2000 rpm for a Regen? After ruling out cables, I think I would disconnect the battery for 5 minutes or so and see what happens.
Some Kubota dashes also report error codes after pressing a sequence of buttons.

good idea. I will try that.

Sounds like a call to the dealer to diagnose and fix the issue. Again, every time I read these posts, I'm sure glad neith of mine have any emissions junk on them.

You coudn't give me any T4 tractor.

Yeah. My old early 60's MF was sometimes a pita but I could always get it running.

It may not be that but I was wary of the regeneration process when I bought it. Just another something to go wrong. And computers too. There is a lot to be said for keeping it simple.

Sadly, not the way it plays today and why the tractors I have will never be replaced in my lifetime. My forever tractors.

What year is it? If I recall correctly they have a 5 year warranty.

Anything emissions related by law has to be warranted for 5 years, no exceptions. The problem will be getting a dealer to fix it promptly.
