    Default JD 990 with a 8a Backhoe

    JD tech says that this JD 8a backhoe can not be attached to a JD 990 with a 430 Loader !

    I have the JD 8a with a 4" channel subframe but I do not see any attachment points on the rear of the tractor .

    Anybody have this combination installed ?

    Or do you have a JD 8b Backhoe installed and can show me the attachment points to make a DIY attachment.

    Thanks,
    Al in Dundas, ON

    Thanks Sal64 for the reply. Pics are worth a thousand words !
    So the tractor reinforcing frame is a 5" x 1 3/4" boxed channel ? Which is the backhoe support channel size.
    And the forward attachment point is the lower loader pivot at the brake pedal ?
    And the rear attachment is bolted to the ROPS supports ?
    Thanks,

    Okay, now it makes the parts list sensible.
    Just looked under my 990 and see what goes where.
    Thanks again,

    Hi Sal,

    I bit the bullet and ordered JD Kit BM17019 on Dec. 21, 2012 and picked it up today; makes much more sense than chasing down and McGyvering the ? 790 ? sub-frame that came with the JD 8A Backhoe, bolt ur on and extend the hydraulics to the mid-point.

    Thanks again,

    Hi Al, congrats on the purchase.

    Curious as to why you mentioned the 790 ?, also curious as to how much the kit cost you ?

    I've got a 790 w/ 3pt hoe and at times have thought of a sub-frame upgrade.

    Should have said the JD 8A Backhoe came with a frame which fits a JD 50 or JD 70 series tractor.
    The kit cost $ 1800.00 CDN with tax.
