There might be a steering or low hyd fluid issue here but set that aside for a moment. Also, check your front 4WD axle since they all need SUDT added.
Now, even if the dealer did everything right by farmer terms, I think they fail to understand the Kubota buyer. They are smarter, better heeled, more demanding, less forgiving and often know more about the product than the dealer. They don't want second best and don't mind spending for what they want but want quality above all else.
So, the dealer that delivers a tractor with a broken jerk and no extra grease might be OK for a farmer buyer since they know the drill. But the Kubota buyer didn't really sign up for that and doesn't like it. A saw a dealer years back smirk and chuckle in front of a $40,000 upscale Kubota buyer because they asked a newbie question. I recall thinking how disrespectful that was and was embarrassed for the man.
Well, that dealer is out of business and the people that bought it jump through hoops for buyers, especially Kubota people. I ordered a $6 part that I kind of needed soon but was a week away. Without me asking, the dealer got it somehow and called the next day to say it was in. That's understanding Kubota people.
My new things come through with visible grease on the fittings and I know they left it that way on purpose.
