  • Poly Midroller Wheel Case IH Quadtrac STX 2006+  (OEM: 84162383, 4w-5064)

    Poly Midroller Wheel Case IH Quadtrac STX 2006+ (OEM: 84162383, 4w-5064)

    $525.00

    These are the highest quality midroller available for all Case Quadtrac STX machines made from 2006 through 2022.  These are a single piece original equipment hub-style wheel with encased bearings, and you will need a seal and two bearings per wheel.  These wheels cost $525 if you have a core to exchange, or there is a core fee of $400 per wheel making the net cost $925.00 ea.  These are the OE wheel used on all STX Quadtrac machines made from 2006-2022.  Before then they used a midroller with smaller seals, and after 2022 the STX machines started coming with a 2-piece wheel.  The Steiger Quadtrac and Rowtrac machines use different wheels.

    We can also have your midrollers retreaded with rubber(lower quality) for $360 ea which would take about 2-4 weeks.

    Trackfarmer stocks these OE wheels, as well as a new 2-piece midroller that you can upgrade to which allows you to remove the poly wheel from the hub and leave the bearings and seal in tact to reuse on the next poly wheel.  We also sell a superior seal which will stop leaks if you have them, as well as a spindle extension tool which makes midroller installation easy(Case mechanics use them)

  • Poly Midroller Wheel Quadtrac 9370/9380(OEM: 251343A3, 4w-5102)

    Poly Midroller Wheel Quadtrac 9370/9380(OEM: 251343A3, 4w-5102)

    $525.00

    Case IH has chosen to stop selling these midrollers for the original Quadtrac 9370 and 9380 machines and that makes the core value go way up.  We can sell a poly midroller for $525 if we get a core back, but the core fee is $1000, making the net cost $1525.00 ea. if you do not have a good core.  A good core is a wheel that simply has worn down the rubber without any cracks or fatigue damage in the steel.

    We can also retread your midrollers with rubber for about $360 per wheel.  We do not stock this type because they are low quality.   We can have your wheels retreaded with rubber for $360 per wheel and the process takes about 2-3 weeks once you get them to the factory.  Just call, text, or email for info on how to do that.

    Please contact us directly if you wish to trade in an old core. We will make arrangements for an exchange.
