Draft arms the same for a 54d and 60D for a 1 series?Check that the front draft arm adjuster bolt is still in your draft arms. #3 in the picture, held in with 2 nuts (#2 in the picture). It may have fallen out, or is out of adjustment.
Without it, the front will drop when lifting, and/or the front drafts arms may not/won't engage when attaching the deck.

First, a belated thank you for the response. Unfortunately I did not fully explain my problem. The deck hooks up OK. The problem is when I raise it the front of the deck is lower than the rear.have 1025r three years old with hydraulic lift for 60" mower deck. The deck no longer comes up to where mower is level when in lift position. Rear of deck always higher than front.
