Troy-Bilt manufactures equipment for lawn and garden care. Shredders grind tree limbs and brush into small pieces for you to redistribute in flower beds and gardens. Shredded bark and limbs make an addition to a compost pile to deteriorate into fresh light loam for the addition to your garden. When your shredder blades are in need of sharpening, the blades will not cut limbs into small pieces but will tear the limbs instead.


Step 1

Turn off the shredder and remove the spark plug wire.

Step 2

Turn the two wing nuts on each side of the chute deflector counterclockwise to loosen and pull them straight off. Grasp the chute deflector and pivot it so the opening points straight up.


Step 3

Remove the hairpin clip and clevis pin from the housing and shredder screen. The pins are at the bottom of the deflector and extend through the housing and screen in the chute.

Step 4

Place an adjustable wrench on the two support brace chute mounting bolts. Turn each bolt counterclockwise to loosen and pull them straight out.


Step 5

Remove the three hex head bolts that mount the chipper chute to the impeller. Turn each bolt counterclockwise with an adjustable wrench and pull them straight out. Pull the chute off the shredder.

Step 6

Grasp the hub on the impeller while wearing work gloves and turn it until one blade is visible. Remove the screws, lock washers and nuts. Pull the blade off the hub. Repeat this procedure to remove the second blade.


Step 7

Place one blade in a vise and tighten the handle to hold it in position with the sharp side up. Turn on a hand grinder and make two passes across the blade at the same angle as the blade. Grasp the blade with a pair of pliers. Release the vise and dip the blade into a bucket of water. Secure the blade in the vise and repeat this procedure to sharpen the blade and cool it after every two passes. Repeat this to sharpen the second blade.

Step 8

Reassemble the blades on the shredder in the reverse order of removal. Press the spark plug wire onto the spark plug.


Always wear work gloves when handling or sharpening blades on any equipment.
