What would be the reason to deliver a new tractor with this problem

[ahr6912]

Upon delivering my L2501 HST Kubota brand new tractor, I noticed the front axle right side, those 4 bolts that secure the front gear case to the bevel gear case have all been "wrenched". If that's the correct word, meaning that the bolt head that secures the (Bevel Gear Case) brake/tire rim assembly to the axle looks like it had been removed and then replaced. The other side had no wrench marks, where the paint had been scrapped off the bolt head, only the right side.
The tractor was supposed to be brand new, was close to 0 hours on it. What's your thinking and why would they have replaced that right wheel assembly?
Pardon the photos, I copied them from the workshop manual. The red arrows are pointing to those bolts(4) on the axle.

The L2501 comes crated with the right side axle gear assembly on the shipping crate/pallet. The dealers do the final assembly , set toe in and fill with lube during dealer set up.

Perfectly normal to see the paint off the right hand side bolts holding the gear assembly on.

I did want to mention that there are lots of threads and posts about checking the fluid level in the front axle of these L2501's and similar models due to the dealer set-up and improper fluid levels.

In my case my L2501 was delivered with a tie rod end castle nut cotter key not being installed. The front tie rod ball joint fell off in a few yards of operation.

The toe in was not set and the oil level was low.

I am including a picture of the paint clearly off on the four bolts holding the gear assembly to the end of the axle.

To the dealer's credit they sent out a tech who replaced the crown nut, set toe-in and added fluid post hast after calling them.

Happy tractoring!
