    what to make of an oil sample ?

    I dont know the owners, it is an online auction, i am guessing this must be a municipality selling them since there are about 8 of them, all roughly the same year and all d7s. I would agree with you on the hours thing. I think i would prefer to purchase from a municipality than a private owner i...

    d7e question

    i owned it for about 2 years and cleared about 20 acres with it then sold it, only thing i had to fix was a busted tranny hydraulic hose and the track tensioner.
