Kubota b6000 Rotovator broken

[Jesús]

Hello, the rotavator on my original Kubota B6000 has broken. The bearings on the blade shaft split, and the tractor suddenly stopped, stuck. Has anyone repaired this accessory? Is it very difficult to remove the bearings and replace them with new ones? If anyone has the part number for these and their seals, I would appreciate it. They seem quite difficult to remove. Let's see if we're lucky and someone has performed this maintenance. Thanks, best regards.

I have not, but here is the manual for it.
It lists part numbers and it appears the last 4 digits is the standard bearing number.
