As long as the wheels aren't riding the ground while your deck is at the height you mow at you will be fine.
To level the deck, Cub sells this gauge. It is part # 490-900-0041. You will need to check each blade for the best cut.

When you have the blades parallel with the frame rail you want the front tip about 1/8" lower than the rear of the blade.
