The easiest way that I have found is to remove the deck from under the tractor and turn it over where you can see the blades.
Get a short piece of 2 x 4 to keep the blade from turning and put it inside the edge of the deck where the blade will contact it and unscrew the bolt that holds the blade on. You can also use a C-Clamp if you have one available or just about anything else that will prevent the blade from turning while you are loosening or tightening it.
Put the new blade back on the same way, making sure that you have it lined up on the "star" (Most blades are stamped "grass side" so you should be able to read this when putting the blade on since the deck is upside down)
You can replace them without removing the deck using the same basic procedure but you have to raise the tractor up high enough to get to the bolts and be able to see to get the blades properly aligned when installing them.
I have personally found that the extra few minutes removing the deck is well worth the effort as it gives you the opportunity to inspect it for any other problems and to clean any built up grass clippings if necessary

How do you adjust the pulleys on a 42" 20 HP craftsman tractor mower. The belt burned off and when I replaced it with a new one the new one began to shred


There is no adjustment on these pulleys. Sounds like the belt was over the blade pulley brake arms or idler pulley guide. They will shred a belt in nothing flat.

WHEN YOU TURN THE KEY NOTHING HAPPENS


Hi Tim,

When you turn the key,
  • is the brake pedal fully depressed?
  • Is your full weight on the seat?
  • Are the blades disengaged?
  • Are you sure the battery is charged
Try these out..

Best regards

Mike

Blades do not spin fast enough to cut grass


If you got the right oem belt,ta\han you can look at the end where the cable attachs to spring and you should see a double nut adjustment loosen nuts and adjust to put more tension on the belt when you put lever into gear for blades to turn then retighten them .
