Replacing the Auger’s Rubber Paddles

The snow thrower auger’s rubber paddles are subject to wear and should be replaced if any signs of excessive wear is present.

IMPORTANT: Do NOT allow the auger’s rubber paddles to wear to the point where portions of the metal auger itself can come in contact with the pavement. Doing so can result in serious damage to your snow thrower.

NOTE: Call 1-866-840-6483 for information regarding the price and availability of Auger Kit 753-04472or contact an authorized Troy-bilt Service Dealer in your area).

To change the rubber paddles, proceed as follows:

Remove the existing rubber paddles by unthreading the self-tapping screws which secure them to the auger.

Secure the replacement rubber paddles to the auger using the hardware removed earlier.
