I bought the JD kit for my 1025 when I bought the tractor new. I installed the kit. Ultimately, I was mostly happy, though JD did a few things wrong: There were nearly twice as many lines, and some mounting plates as I needed. Okay, so different versions of the tractor may require different lines, but for an expensive kit, I have nearly as much left over as I installed - and I can't return the unused new parts. The major parts (lines & mounting plates) came loose in a large box, with no caps on the lines. So I blew them all out with care. The small parts, including the control stickers were all poured into on plastic bag - the stickers were munched.
I'm happy with the fit and function of the kit, but there were some customer satisfaction misses. I'm kinda thinking that maybe JD parts sales do not intend that the tractor owner do the installation. If done at a JD dealer, the tractor owner would not see the wasted excess parts!
