How to Replace the Auger on My Craftsman Snowblower
Keep the Craftsman's auger sharp for maximum snow-clearing performance. (snow image by Marek Kosmal from

Craftsman's snow throwers allow you to clear heavy, hard-packed snow by utilising a large steel auger that is serrated and curved. This auger breaks down tightly packed snow, letting the thrower remove the snow from a path. After years of heavy use, the auger may become worn down or damaged. Replace the auger when the part no longer performs properly. Install the auger on the snow thrower, which also is called a snowblower, in a few minutes.

Skill level:


  1. 1

    Release the tractor's attachment clutch, if the snow thrower is connected to a tractor. Remove the snow thrower and lower it to the ground.

  2. 2

    Remove the snow thrower's attachment pin. Place the lift handle in the "Down" position to lock it. This action decreases the thrower's belt tension.

  3. 3

    Locate and release the auger belt idler arm's spring tension underneath the clutch and idler assembly.

  4. 4

    Lift off the auger drive belt that is on the clutch and idler assembly. Pull the belt out of the spiral auger housing.

  5. 5

    Place the new auger belt over the large auger drive pulley and underneath the two side idler pulleys. Turn the auger belt one quarter turn until the "V" notch in the belt is seated in the groove of all the idler pulleys.

  6. 6

    Set the belt on the clutch and idler assembly. Return the assembly to its original location in the snow thrower. Reattach the thrower to the tractor, if necessary.

Tips and warnings

  • Shut off the snow thrower's engine, remove the key and set the parking brake before changing the auger belt.
