FAQs

This belt is a direct replacement for OEM part numbers 405143, 532405143, 584453101, 21546607, 7133156, 575937701, and PP21008.
This is a 1/2-inch wide belt with an effective length of approximately 106 inches.
This belt is designed for 46-inch mower decks on equipment from Husqvarna, Craftsman, Poulan, and Ariens. Compatible models include, but are not limited to, Husqvarna 2246LS, 2346XLS, YTH22V46, YTH20K46, YTH21K46, YTA1946, and Poulan models such as PB19546LT, PB195H46YT, PB20H46LT, and PB22H46YT.
You should inspect your belt if you notice the mower deck failing to engage, excessive slipping or squealing during operation, or uneven cutting. Physically, look for signs of dry rot, fraying, stretching, or cracks along the inner V-groove.
Before installing the new belt, inspect your deck pulleys and spindle bearings. If a pulley is seized or a bearing is worn, it will cause the new belt to overheat and fail prematurely. Ensure all debris is cleared from the deck housing to prevent obstruction.
Replacing the deck belt is a standard maintenance task that typically takes 30 to 60 minutes. You will generally need basic hand tools, such as a socket set or wrench, to release the tensioner pulley. It is helpful to take a photo of the belt routing before removing the old one to ensure the new belt is threaded correctly through all guides and pulleys.
