Dirtwisperer, glancing through my manual, which covers the Kubota Grand L Series models 3130 thru 5030, it states:
Two wheel drive models - you can adjust the front axle out about 12".
Four wheel drive models - the front wheels/axle cannot be adjusted.
The rear wheels - on the two and four wheel drive models - can be adjusted by changing the position of the rim and/or disk (about 12") also.
As you can see, Bird again has the correct information.
This forum keeps my manual from gathering dust and I learn a lot also. /forums/images/graemlins/smile.gif
