Here's what I could find.Have a Zipper STS with a couple bad spindles. At least one certainly needs replaced. Curious where to go for aftermarket spindles? I will probably have to resort to fitment based on dimensions.
Mowingman gave a really good answer, google it....I should be more descriptive. I am looking for an aftermarket supplier that makes replacement spindles for many different mowers, where I can obtain dimensions and specifications so I can so I can use my industrial background to select spindles the the application.
Really ? How did you determine that ? Most aftermarket spindles are cast chinesium units. Made in china. Have you tried Stens ? Oregon ? etc. ?but appear to be extremely common cast iron units.
