Additional Information

Did you know the 521017M91 muffler fits more than one lawn mower/garden tractor? TractorJoe does, which is why we strive to verify our parts, ensuring they fit your Massey Ferguson properly. This muffler is not only made for the Massey Ferguson 10 lawn mower/garden tractor, but fits the Massey Ferguson 12 as well.

It can be pricey to replace a muffler on the Massey Ferguson 10, 12, or really any lawn mower/garden tractor. That's why we sell new high quality mufflers direct at often lower prices than even a used Massey Ferguson muffler!

We back our parts with an industry leading warranty. Whether you have the 10, 12, it's important to keep your muffler running smoothly. So when something breaks in your Massey Ferguson, TractorJoe can help.

It doesn't matter if you're installing our muffler in your Massey Ferguson 10, Massey Ferguson 12, or something else, we'll be here for you. Our staff knows a lot about Massey Ferguson lawn mower/garden tractors, and our Q and A community is there for any other questions you may have.

Frequently Asked Questions
When will I get my items?
Once your items have shipped it takes around 2 to 4 days to arrive at your location. You can track the shipment to find the expected delivery date or if there are any issues that have caused a shipping delay. Destinations outside the continental US will take additional time for delivery.
What if I will not be available to receive my shipment?
We've got you covered! Delivery carriers will generally let you leave a signed note on your door with instructions. UPS will generally leave a ground shipment at the door in rural and suburban locations without a note. You can also instruct the UPS driver to take it back to the customer service center for pickup if you do not want it left. For detailed information please contact the delivery carrier.
Can you ship to an APO/FPO address?
We unfortunately are no longer able to ship to AFO/FPO addresses.
How much is shipping?
Shipping costs vary based on product weights and where you're sending it to. You can calculate shipping costs in the shopping cart or checkout page.
