Did your John Deere pencil injector give up on you? We're here to help. Our replacement HR50781 pencil injector is built tough and fits industrial/construction machines, tractors and combines, including the 500, 500A, 500B, 600, 500C, 510, 3010, 3020, 4000, 4010, 4020, 4040, 4230, and 4520. We strive to keep your John Deere running for the long term, which is why we sell quality pencil injectors that are built to last.
Whether you have the 500, or something else, John Deere pencil injectors are expensive and thats why we sell pencil injectors direct at significantly lower prices than your John Deere 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 pencil injector more than you need to, which is why we back our parts with an industry leading warranty. Even if your 500, 500A, or 500B is not your main piece of equipment, TractorJoe knows that having it up and running is always important.
It doesn't matter if you're installing our pencil injector in your John Deere industrial/construction machine, John Deere tractor, or something else, we'll be here for you. Our staff knows a lot about John Deere equipment, and our Q and A community is there for any other questions you may have.
