2320 Mowing Deck lift - how high should it come?

I have a question for you fellows with the 2320 and the mowing decks. I have a 54" deck but I assume the 62" would be the same.

On the right front corner of the deck there is a vertical steel plate which, if I understand the book correctly, is called the "upstop". I guess the theory is when you lift the deck if it comes too far this plate hits the bottom of the tractor frame and stops the deck before any damage occurs.

Again, if I understand the book correctly, when your deck is lifted all the way up the "upstop" plate should come to within about 1/16" of the frame. I "think" I understand that's what they are saying.

But mine does not do this - so here's the question. When you guys lift your deck right up as high as the hydraulics will take it - how much room do you see between the bottom of the frame and the top of the "upstop" plate?

I have a feeling my deck was set up way too low by the dealership, which would explain the problems I am having with setting my cutting height.

Any and all thoughts would be appreciated. I'd sure like to know how far other decks go up.

The height adjustment knob should not rotate 360; it should stop at each end of the left to right rotation. The knob can be a real PITA itself if it wasn't installed or "calibrated" correctly.
The distance between the deck and upstop plate should be no closer than 1/16"; if it's a little more that's fine.
The link pins shown in the pic are the principal way to adjust the height, but the front lift arms (the ones at the front of the deck and attach to the tractor also need to be in sync with the links. I struggled for a year with getting the balance right among the several links, rods and the knob.
Also, keep in mind, the deck wheels aren't supposed to ride on the ground. The deck literally hangs from the tractor.
The independent lift hose may have to be rerouted. Mine did. It was a stretch, but it was doable.
Last November, I traded the 2320 for what had to be one of the last new 2720's in the USA. I loved the 2320, but after 90 hours on the 2720, I love it even more. And there's no adjustment knob, which I did not like, no zerks buried in the belly and tons more power.
Best of luck getting your adjustment. Take your time, say what needs to be said :) and keep at it. It will work out.
