Ok, so it seems I have almost 5 inches of height. Mine is adjusted so well that the auto connect feature works 99 percent of the time. The second picture shows how I can just barely fit my finger between the lift arm and fuel tank skid plate. The last picture shows where to adjust the lift arms. adjust both sides at same time. It will require you to remove and attach the deck several times till you get it right. You may have to adjust the drag on the front attaching hardware as well. If you get stuck doing this, I will have to scan my mower deck manual for you and send it to you. I can already see by your pictures where the lift arm meets the fuel tank skid plate that the delaer really screwed up the install. Freakin typical of those idiots. You have a ton of adjustment left
I have the manual too, thanks for the pics. I will have to try out what you are saying and see how well I can adjust the deck. I did not believe that JD would design a deck that would only fit on the tractor so low. Unless there is something drastically different with the mounting about the 2008 vs the 2012 3520s? I do have the front 3PT hitch installed, could that actually make a difference, as the front of the deck is pretty low as you can see from the pics. My dealership has been excellent sofar, and they were very helpful in installing the non-drive over deck that I still have.
BTW, can you take a pic of your mower mount from the front end view like I did?

no the 3pt wont make a difference buddy. You need to adjust the rear links. after you do that, check the measurements on the front and rear of the deck to make sure it is level. If the rear is good after adjust ing the rear links and the front is too low, adjust the front drag links. Your machine is just out of adjustment. once we get this fixed you will be good to go. I don't think you will have to touch the front links though. I think that only affects the auto connect adjustment but start with the rears and report back

After looking at the 1st picture I see room between the lift arm and the stop. Like Mike said, adjust those rear lift arms up. Again, there should only be 1-2mm worth of spacing at transport height.
OK, I did my first adjustment and I got almost 3" of cutting height now. I also think I know why the dealers are having so much trouble. The manual states that the that the PTO coupler should be adjusted so that it is parallel to the lower plate of the coupler. If they don't read this in the manual and allow it to dip below that lower plate lip, then it can be very hard to get the coupler to work correctly and you cannot attach the deck.
I plan to adjust the deck up higher next weekend. The cut I just finished on my lawn is way better that it was at the lower setting.
Thanks for all the assistance everyone!
Yep, you are correct.
