BX Hood Shake

[JOHNTHOMAS]

I have owned a BX since 2003 and if you don't loan it to a drunk uncle or someone who knows or cares nothing about equipment, the only work that needs to be done will be regular service such as oil changes etc.

I've owned 15 different models of Kubotas in almost 10 years with most of them being BXs and Bs and I agree with TripleR. Very rare to hear of any problems with the Kubota subcompact and compact tractors from the original purchasers no matter the total hours. I agree 100% with TripleR. My brother can tear up a steel ball and I even loan them to him with no worse for wear.

The shake thing is alarming and somewhat annoying until you get used to it.

The biggest problem is what the vibration does to engine components and mounts. The air cleaner bracket has broken at least 4 times on my BX. Each time it is welded back together with a little more support and bracing. Might have it right now - it has gone 100 hours without snapping.

Most people rev the engine a bit until the shakes smooth out. It sounds a little high but at least the hood and whatever is loose is not clanging. I used 1/2" weatherstripping around the hood closure area and that seemed to help.

There are several threads about the shake and the air cleaner bracket with some unique solution. Here is one example:

It does not change what the engine does but these little bumper can be used to keep the hood from shaking.


4shorts may have first mentioned it in is mod thread.

Nope. Can't take credit for that one BUT I think there's a fix for the dreaded shake. IF I were to take two small double acting shocks and go from the motor to the frame on each side of the block I'm thinking it would solve that issue. That being said there's nothing going to happen with the way it is now BUT I just got to try that mod

As a BX owner since 2004...Normal and no damage will be done.

I've personally have seen and dealt with that issue. Cracks off the bracket like a match stick. :shocked:

It's not only the 3 cylinder engines that shake when idling slowly or when you shut them down, the 2 cylinder BX 1500 does the same thing.

So it seems like everyone with a BX has the hood shake on shut off.I was hoping there was a solution,like maybe adjusting the timing,but apparently not.It is probably the only thing about the tractor that I find annoying.

It is not just limited to the Kubota's, my Massey GC 2610 does it too. I think it has to do with such a small framed tractor, not much weight to counter power ratio of the engine that lends to the shake.

Just like what everyone says,bx does shake at shutoff.nothing we can do to make engine smoother, as far I know.

Maybe the nature of 3 cylinder engines.
