## Product's reviews:
- Excellent - We recently purchased a 30-year old hydroseeder and have no manuals or parts diagrams for it. The manufacturer is since out of business and there is very limited information on line. The most critical part we needed was a Dodge part. The original part was clearly marked with the Dodge name and part number. MRO was quickly able to identify the replacement part and we had in hand in two days. Perfect fit. Thank you MRO Supply for helping make our machine functional.
- Bearings - Order arrived on time, could have been packed a little tighter as the boxes the bearings came in were tore up. All is good as i used all of them instead of leaving them set in inventory.
- Bearings - Correct bearings, came the first time!
- Great! - Cheapest price I've found on the web.




## FAQ:

- How does Dodge warranty evaluation work if a product fails?: Failed units go to Dodge's US plants for evaluation — about a week in transit plus one to two weeks of analysis, and you get the findings either way. Warranty covers workmanship and material defects; failures caused by the application (lubrication, installation) fall to the customer, but the failure analysis tells you the root cause so it doesn't repeat.
