Front Differential on Kubota 135x

[Goat08]

a few days ago we put a reman engine in the M135 kubota went relatively simple except for having to tear virtually half the tractor apart. Long story short we reinstalled the front end under the tractor drove it around the shop a few times good as new we thought. Went to drive the tractor home got about 5 miles down the road and the front end locked up. Lifted the front end with loader tires spin freely but output shaft going to tranny will not budge. Talked to a local hobby mechanic said there is a mechanism that will lock the front end in case of a low oil in differential. Has anyone heard of this?????? Or have an expertise on larger kubota's?????

There is no such mechanism. If you check your front axle oil level, it probably is very low and the pinion bearings seized from lack of lubrication.

I assume he's bailed. Probably figured out by now what and where his problem is and now he's working on what to do about it.
