Never experienced what you're saying. We did hundreds of "seeding/aeration" jobs this fall. On a county highway where they dug the ditches "deeper, the XT5 was the only aerator that would "climb" the slopes and go around culverts. Difficult situation.
Regarding breakdowns - Never seen one on XT5 or T3000.
