FAQ

This pulley is a direct replacement for OEM part numbers 177968, 193197, 532177968, 532193197, 21546308, 21546847, 705061, 708000, and 11634. It also cross-references with Stens 280-240 and Oregon 78-013.
This pulley fits a wide range of riding lawn mowers and tractors from Husqvarna, Poulan, Craftsman, AYP, Ariens, Dixon, Snapper, and Murray. It is commonly used on 42-inch, 46-inch, 48-inch, and 54-inch decks, including models such as the YTH series (YTH20K46, YTH21K46, YTH22V46, YTH2348, YTH2448, YTH24V48), Z248F, Z254, and various RZT series units.
Common signs include a high-pitched squealing or grinding noise coming from the mower deck while the blades are engaged, excessive vibration, or the mower belt frequently slipping or jumping off the pulley. If you notice the pulley wobbles when you move it by hand or if the bearing feels rough or seized, it should be replaced immediately to prevent belt damage.
Before installing the new part, inspect your mower belt for any signs of glazing, cracking, or fraying. If the old pulley failed due to a seized bearing, it likely caused heat damage to the belt, which can lead to a premature snap. It is also a good practice to clean the deck surface of debris and check the mounting bolt and hardware for wear.
Replacing an idler pulley is a straightforward maintenance task that typically takes 15 to 30 minutes. You will generally need a socket set and a wrench to release the tension on the mower deck belt. Ensure the mower is turned off, the spark plug wire is disconnected, and the deck is in the lowest position or removed for easier access.
