I didn't notice at first that your front eyelets are adjusted all the way. That's odd. Maybe where your eyelets ride on the lift arms, it's really worn there. You may need to weld up that area and then grind it down to specs. You could add some shims or washers between the rear hangers and the deck. That would drop the rear of the deck. I'd also check to see if anything is bent or damaged. Just remember when you have your deck at the desired cutting height, the gauge wheels should be set to about 1/2" off the ground. I think the manual calls for the rear tires to be at 10 psi. That would lower the rear of the deck a little bit but I think that's probably not the source of the problem.
