JD 990
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,

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.
