Craftsman 42" riding mower deck height

i have a Craftsman 42" riding mower and i recently had an issue where i hit something and the deck was uneven and the blades busted. I put new blades on and had the deck adjusted to become level again. The problem is i think now the mowing deck is too low and even on level 6 the grass is short and i didn't notice at first and now most of my grass is burnt from being too short.

anyway my question is there manufacture instructions or specs that tell how high in inches off the ground the mowing deck when it is at each level 1 to 6. I want to adjust it but i want to know exactly how high each level should be off the ground.

thanks in advance
