Did your International Harvester muffler give up on you? We're here to help. Our replacement 530578R4 muffler is built tough and fits more than one tractor, including the International Harvester HYDRO 70, HYDRO 86, 666, 686, 706, 766, 806, and 826. We strive to keep your International Harvester running for the long term, which is why we sell quality mufflers that are built to last.
Whether you have the HYDRO 70, the HYDRO 86, or something else, International Harvester mufflers are expensive and that's why we sell mufflers direct at significantly lower prices than your International Harvester dealer. You can save up to 70% with TractorJoe.
Price is just one part of the equation though- quality matters too. We don't want you replacing your muffler more than you need to, which is why we back our parts with an industry leading warranty. Even if your HYDRO 70, HYDRO 86, 666, 686, 706, 766, or 806 is not your main tractor, TractorJoe knows that having it up and running is always important.
It doesn't matter if you're installing our muffler in your International Harvester HYDRO 70, International Harvester HYDRO 86, or something else, we'll be here for you. Our staff knows a lot about International Harvester tractors, and our Q and A community is there for any other questions you may have.
