One of the better investments I made after purchasing my JD970 was to pick up the technical manual for the 670-1070 series CUT's on Ebay. I got the genuine JD copy and it has the fold-out's detailing the hydraulic system, electrical, etc. Very helpful as I was able to then add both front and back work light's as well as plumbed in a hydraulic cylinder into the power-beyond system to tilt the angle for my 7' backblade.
I continue to see copies every now and again offered on Ebay when I'm scanning for copies of operator/repair manuals for the other implements that came with my tractor package. Good Ebayin'. /forums/images/graemlins/smile.gif
