How to level a murry 46 cut mower deck?

first check all your tires pressure. then park the mower on a level concrete surface and drop the deck to the ground. then reach up under the frame but above the deck in front of each back tire and loosen the big wing nut. do this on both sides. then go to the deck height adjuster and pull the plastic cover off the lower end slots and lower the handle all the way down and lock it in. now all you have to do is tighten the wing nuts under the frame and then pull up the height adjuster handle and you have leveled the deck. one more thing if your deck has gage wheels on it you really need to take them off for this leveling job
