Hi Eddie,
I don't know but I'd guess someone has had some kind of axle failure before ... I dunno?
Your question about the same axle as last year ... it was not the axle itself last year. If you remember, it was the the small bevel gears on the axle and front drive that stripped. I replaced them. This failure was a cracked casting. The gears I replaced are inside it. The casting cracked where a sleeve on one fits into a bearing on the other casting.
I might off base, but I think I know what you're getting at though.
And that's OK with me if that's the case ... (correct me if I'm wrong).
I know you're not a fan of Chinese tractors and question their reliability. I seem to have bad luck breaking things that most others don't.

I'm pretty sure I use mine the same as other brands and perhaps shouldn't have some of these failures. Maybe it's because it's an inferior machine? But then again, maybe I use mine a little differently too exactly for the same reason? It's not like I'm worried about breaking an expensive tractor. There are a lot of things I do with mine that I should really have a bulldozer for, but I don't, so I'm a little hard on the machine. I think though, that if I crashed into a boulder with any brand machine (same size) there is a good possibility that their casting would break too.
I just bought a brand new 2008 Silverado 2500HD earlier this year. Guess what, Loretta accidentally backed up into a huge Oak and we had to replace the bumper and rear quarter panel because they were crushed. I paid over $40,000 bucks for that truck. I think a Ford, Dodge or a cheap Chinese truck would do the same, don't you?
Sorry in advance if I'm off base Eddie. LOL ... Maybe I read too much in your reply and perhaps you were suggesting I'm just a crummy tractor operator.
