Have a craftsman mower just purchased riding how do I get the blades to work so can cut yard

SOURCE: replacing the blades on a craftsman dyt 4000

Not a hard job, but you will need a couple of tools. First, you will need a wrench that fits the nut that is holding the blade on. I prefer a closed end wrench, but an open end will do. Second, you will need a blade changing tool. The brand name is called a Blade Hog. It attaches to the deck and holds the blade in place so you can turn the nut. Raise the deck as high as it will go, attach the Blade Hog, and then loosen and remove the nut. Be sure and pay attention to which side is up on the old blade and put the new one on in the same manner.

hope this helps,

SOURCE: Craftsman 42 inch riding lawn mower is not cutting evenly

The first thing to check is your blades. If one is bent, it will never cut even. It happens a lot hitting roots, antbeds, etc. Mulching blades will bend easier than a straight blade. It's best to take them off and lay one on top of the other to see if they're bent.

Was it cutting uneven before you changed blades? If so, you may not have gotten the blade on the shaft correctly. There is an adjustment in the center of the deck hanger on each side. You can turn the 9/16 nut up or down on each side to level it out.

craftsman decks have a positive stop adjustment for the decks. A spring atached to the blade ingadgement arm pulls the tension pully into position if the cable is rusted inside the sleeve it wont put enough pull on the ingadgment pully and thus the blades dont spin full force the belts on the mowers have no adjustments only the pully . second thing is you may want to drop the deck and clean around that pully by scraping any rust off the surface under the pullys slide good luck
