Lazer Z Deck Adjustment

Everything looks good to me. The remaining adjusting chain goes slack amd will not allow the deck to lower anymore.
Measure those chains. Make sure they are all the same length and that every chain is the exact same link size. Also, the same number of links in each chain. Something isn't right.

There are 5 links at all 4 adjustments and on level cement. All links are the same kind.

Have any of the tires been replaced?
Set tire pressure to 12 psi all around.
Do you have a couple of levels?
Use to check level of ground and deck.
You can also use as a straight edge to see if your deck is straight.
You said that one chain is slack. That indicates that the deck is hanging by 3 chains.
 
I’m good for all of your suggestions.

Imagine a (36” x 54”) 1/4” steel plate with hook eyes at each corner. If you lifted the plate by 3 corners it would be raised above the ground. I think this is what is hpening.

At any rate the grass cut looks excellent to me as is. I appreciate your help… Thanks.

My old Toro Titan had the same setup with the chain deck hangers. It was a lot easier to level than my Gravely Pro Turn 260.
 
Personally, I don't like the rear being 1/4" higher than the front. I don't get a good clean cut with the deck set like that. I get a cleaner cut with the rear 1/8" higher.
@Tiger Small Engine said level all around. It's worth trying.
Think of it this way. Most push mowers can only be set to mow at level all around. Some people scoff at setting zero turn decks like that. Also, take a look at lawn tractors, the decks are usually set up level all around.
Play around with it. See which setup works best for your particular mower.
I always pitch the front of deck on riding mowers 1/4” lower than the rear. This not only makes common sense, it is what every service manual states.

Not every service manual. Generally, it's anywhere from 1/8" to 1/2" depending on the manufacturer. The results must be judged by the operator and adjusted to achieve the best results.
