BX2660 Idle Speed

BX2660 Idle Speed??

My recently delivered BX2660 has an idle speed of 1450 RPM which seems a bit fast when I turn the key off. The dealer told me that Kubota does not specify a min/max idle speed and the BXs they have sold have idle speeds ranging from 1000 to 1450.

For all you BX2660 owners out there-What does your BX2660 idle at and have you had it changed since you took delivery?

Mine is around 1380. I thought it was a little high but have not changed it. I'm curious to know what others are too.

 

[robertm]

Mine's around 1400, too.

 

[dodge man]

Mine flops around between 1250-1350.

I would have to check as I never "idle" except to bring it down and immediatelty shut it down; too much shaking at idle for me. I run it just fast enough to smooth out.

The higher idle speeds may have more to do with tier 3 compliance then anything else, low idle engines run colder and do not burn as clean.

Finally checked as I got a little tractor time today, looks like mine is at the low side per responses, at 1250 +/-

Mine is about 1400 give or take a few, i too was curious when i first saw it but i looked in the kubota manual and it emphasizes a target rpm, i do not remember what that is but i do know that my rpm is normal for the 2660 so it shouldnt be anything to worry about

My BX24 is right at 1450 since new. Seemed high to me at first is also, but nice and smooth at that rpm; the only shaking is right as it starts and when I shut it off. Since the tach is electronic, variations seen might but in the method of getting the reading rather than the true engine rpm. It is most important to pay attention to the RPM required for proper PTO speed (it's in your manual).

My 2008 BX2350 since new is 1150rpm.

 

[RMatty]

My 2350 is also 1150-1200 rpm

 

[JOHNTHOMAS]

My BX2660 1400-1500.

Darn, I only remember to check my BX2660 idle when I'm online. I guess I need wifi on my Bota.

 

[Barnone]

My new BX2660 idles at 1400+ RPM which seems high to me as my eight year old BX2200 idles way down.

Should I adjust the idle down on my 2660 or leave it alone? I'm guessing that the high idle RPM doesn't hurt anything.

If I should slow it down, where is the adjustment?

EDIT: Found this other thread so maybe I "should not broke it if it ain't fixed" :laughing:

This makes total sense to me. My guess is that emissions are the reason we see the increases in rpm for rated hp and the 540 PTO output. I think some of the new smaller engines are rated at 3000 rpm or higher?

 

[leonz]

Dont forget the timing has been advanced to reduce the emmisions
and that has huge part in the shake rattle and roll as well as the high and low idles.

Our '09 BX2660 idles at 800-900 RPMs, but shakes the whole tractor doing it.
You don't get any aux (3 point, loader, etc) hydraulics until ~1350 RPMs.

The BX's shake the hood quite a bit at idle. I wouldn't be surprised if the dealers turn them up just enough to alleviate the rattling.

 

[oldballs]

Since new (now at 250 hrs) it idles cold or hot @ about 1400 rpm (+/- 50), and shudders rather violently when turned off:confused3:.

 

[JMace]

New BX2660 (15 hours) idles between 1350 - 1400 (based on the little digital tach).
