B3200 Vibration Update

[kuboman]

This is a photo of the remote joystick on my B3030. For my use it seems better than the new style on the B3200. Mine is the remote from the cab model.

That looks like a nice unit. When you come away from the loader is the valve with the upright or is it mounted on the tractor.

The valve stays on the tractor.

It is strange that Kubota does not offer that setup on the no cab models. Looks like a far superior setup but likely more expensive.

It's an option on the non-cabbed models. You have to pay extra for it.

It is great to get some information. I wish I had found this sight before I bought mine. I asked the dealer about different control configurations on the 3030 and the info I got was there was one option and that was the control on the loader pedestal so I ended up with the 3200 for that reason and $$$$. All dealers are not created equal.

That is the correct answer as the joystick is mounted permanent to the fender. It is from the cab model. My dealer didn't really know much about this joystick but I provided pictures from this forum and paid I think less than $ 200. It was a year in Dec. from purchase so can't recall exactly. It has worked great for me and I just rolled up 70 hrs. on the B3030.

I've had Kubota tractors for over 30 years now. Vibration was never an issure on the earlier units. I just purchased a new B3200 and the vibration and noise are unacceptable.
I'm a consulting engineer for noise and vibration. I get to measure the vibration on many different engine powered machines, many of which use Kubota engines. My professional opinion is that this vibration is excessive.
I have a parts list for the so called "fix" and I don't see how it can "fix" the problem. Maybe it will reduce the vibration on the feet but that isn't the problem. It's the overall vibration on the entire machine.
Without doing an engineering study, I would have to say that the engine is not a smooth as it could be. I don't know if it has internal balance shafts or not but it's hard mounted to the frame. It does not have vibration isolators, as are the engines in the BX series.
I will be returning my B3200 to the dealer.

I read in another forum that they can adjust the timing to relieve some of the vibration. They apparently adjusted the timing for emissions which made the vibration worse. I am looking into this but have yet to get any hard info. It does make sense though.
The B3030 uses the same engine but it is tuned a little different for the lower hp, and they do not have a vibration problem.

This is a direct quote from another online forum member with the same problem and what the solution turned out to be.

"I’m a happy owner of a new B3200 with information for those with concerns over the vibration issue that some have written about. First, when I first learned about the B3200 I compared it to the 2720 and test drove both a number of times and read reviews as much as I could. I purchased the B3200 because of the slightly larger size, the 3 speed transmission, 4 cylinder engine, and because the areas Kubota dealer (Blazey’s, Palmyra NY) was service oriented and the local JD dealer was not.
When the B3200 came to my home it had a vibration that I found unbearable and I returned it to the dealer prepared to trade it in on another model. However, by installing rubber mounts on the deck and resetting the timing to the required specs for this engine, the vibration issue was solved. Apparently when these 4 cylinder engines leave the factory, the timing is set to accommodate new omission standards and not set for optimal performance or to their design specs. These two steps solved the problem and I’m very pleased with my B3200 with just 10 hours on it now.
Anyway, for those looking at the B3200 before you pass on it because of vibrations, ask the dealer to do the two things put rubber mounts on the deck and adjust the timing before you make a decision. Because these threads were of help to me during my purchase decision, I could not help but share my B3200 experience with the rest of you. "

Let us know how you make out seems like it worked for this guy

I think they are the same horsepower, just rated at different RPMs.
