Sent the wrong belt and took almost 3 weeks to show up disappointed in the kit for being a deck rebuild kit it’s missing 3 pulleys
We're sorry to hear about your experience. Receiving the wrong belt is certainly frustrating, and we apologize for the shipping delay as well. Regarding the deck rebuild kit, the listing includes photos and a complete list of everything that's included, so while it isn't intended to contain every pulley on the mower deck, we understand how that could have been unexpected. If you haven't already, please reach out to our Customer Service team—we'd be happy to make sure you have the correct belt and help identify any additional pulleys you may need. Thank you for your feedback.
The parts came on time and they fit perfectly.
Working great, worth the money
The deck rebuild kit I purchased was money well spent. Would highly recommend it.
This kit made spindle replacement fast and easy. The new belt runs smoothly and is quiet. Kit would be better with out the blades as I have 2 sets of mulchers on hand.
