That model has a very complicated and elaborate 4x4 system.
It is hydraulically engaged and lockable, dual speed setup.
There will be several controls (most likely via push button) that control the system.
The next questions are not to insult your intelligence just information.
Why do you feel it's not working, does it spin the rear tires without any front spin on either wheel or both with the diff lock engaged?
If this is the case then yes it needs work done on it, could be something simple, or complicated, but this is why you have a warranty.
Do you notice any change when you engage the bi speed turn option (which on this model doubles the the front wheel speed on tight turns)?
Note: I did not find any 4WD on or off switch or lever so I assume that it's possibly full time 4wd, confirm this with the dealer.
Also if you want to help yourself troubleshoot this or future issues get the WSM for the tractor.

Hey, the guy who leases my land had the same problem. What happened to his MX135 was a roll pin where the front drive shaft goes into the front end broke and allowed the spline to back out. I don't know if I am ,or can explain it very well. Just follow the front dirve shaft forward. It is housed in a hollow tube. And just before it goes into the front axle there should be a little panel or cover to remove. Inside there was the broken roll pin. He said it was pretty easy to fix once he fount the problem. Hopefull it's that simple.
I'm glad it was just the roll pin. As far as the service recall goes, I would just call your dealer's service manager and inquire about it. Good luck.
had this happen to my 135 gx the square part with the four holes holds the u-joint that feeds the mfwd wore loose witch in turn caused the knuckle to hit on the bottom of the oil pan a lot on noise and vibration this was the only issue I have had in 3900 hours of use it has front suspension thus the need for u-joints on the shaft great tractor use it every day
