L3940 vibration while diving

[atechbh]

My new (2013) L3940 vibrates bad over 10mph while driving even in 2wd
On any surface I have the industrial tires on it the same as on my L3240 and it had no shake. The dealer tells me it normal on the 3940 because of the camber. Definitely does not feel normal. Has anybody had anybody had this issue?

Any help here?

So, on a very soft surface it vibrates?

Only thing i can imagine is a driveshaft
That is out of phase.i dont think its possible
With these new fangled machines.

Tire pressure - lower it and see if vibration
Changes.

The kubota rep drove it and said it is normal on that model because of the front camber. But doesn't seem right. Shakes like crazy at 12mph and goes away at faster speeds.

Harmonics can do that to any vehicle. You should notice it even on cars and trucks. They have their super smooth speeds and their more rough/squirrely speeds. Modern vehicles have good enough suspensions to make this almost unnoticeable, but you'll notice your tractor suspension has more in common with a Conestoga Wagon than a modern car suspension!
