This is an Original Manufacturer Sourced replacement part used on certain Lawn Tractor/Riding Mowers. This part is made out of metal and is sold individually. Mandrel Pulley plays and important roll by transferring the energy/motion from the Motor to the Blades using belts. If the Pulley is bent or damaged it will affect engines performance and should be replaced to avoid further damage.

Amazing Service
The parts I ordered were exactly what I ordered and worked perfectly. I would prefer to review ereplacementparts.com instead since all the parts I have received over the years have been quality parts that have met my needs. ereplacementparts.com has always delivered excellent service! My orders have always been filled perfectly. And I am always amazed how quickly they are filled. Often I get a note that my order had shipped after only 24 hours or less, even when I order on a weekend. I think your service is amazing! Thank you!

Part fit the same as OEM. Shipping was longer than I have experienced in the past buying parts from E Replacement. All in all, another great part from a great company to do business with.
