abuse or just normal wear

Did you buy the B7800 tractor new, or did it have a previous owner?

Are you the sole operator of the B7800 or do employees operate the B7800 too?

I bought it new in 2007. treated it pretty good for the type of work it does. all maintenance to the book to this point as far as oil changes, filters, etc. I am 99% the sole operator.

as for rear ballast, most of the time I have had a 3ph implement on. especially as of late (last 600hrs or so) and the last 600hrs is when these axel problems have showed up.

was wondering if the rough north cen. pennsylvania ground/logging roads caused the seals to degrade/fail?

or could it be from compression by ratcheting it down on a trailer all the time?

or would a Kubota L series tractor have held up better then the B series?
