Problem with 4 wheel drive Kubota L4200

[Dwilson540]

Nice video! The tractor does look experienced, like it has seen a lot of pavement.

Assuming the 4wd lever was engaged during the test, if the shifter inside the trans has jumped out of its groove the turning resistance using a foot on the tire would not be very much - problem could still be be back there. Another possibility is the outside 4wd shifter lever is bent or its roll pin is sheared off.

Before splitting the tractor, I'd unbolt the housing under the seat and have a look down inside. Not unheard of for a shifter to need to be pried back into its groove. (I always hope for the easiest fix )

Thanks, I will check it out. I can see the shift lever causing if the part 010 to rotate. But I , like you, go for the low hanging fruit if available.

If it's front axle, have fun. If it was me, I'd have it fixed at a Kubota dealer. Takes quite a few specialized tools to take it apart and put it back together and there are a lot of critical clearances involved too. You ever set drive pinion lash and used paint marker to determine tooth contact and set the pre load on a vehicle. If not, you'd be better taking it so a dealer where the mechanics have done it before.

It's just like the differential in a car plus the outboards and they have to be set as well.

Thanks, I thinkI’ll take your advice.

As others have said check the linkage for the lever that engages the front axle for any missing or loose bolts. A bolt loosened on my BX and it would not engage the front axle because of the slop in the linkage the loose bolt created.
