I needed a forklift part and wasn’t sure which one fit. They asked for the model and serial number, got back to me quickly, and made sure I ordered the right one. Really helpful.

Frequently Asked Questions
Q: Will this idler kit fit a 48-inch Husqvarna deck? A: No, this kit is sized specifically for 46-inch cutting decks found on RZ4623, RZ46i, and Z246 models. Using it on a different deck size may cause improper belt alignment.
Q: Do I need to replace the belt at the same time? A: While not strictly required, it’s highly recommended to inspect the deck belt and replace it if worn to ensure optimal tension and performance with the new idler kit.
Product appearance and specifications may vary slightly by batch. Compatibility may vary by serial number. Verify fitment before purchase.
