Why Choose Broken Tractor:

  • ✅ Engine-matched, not model-matched — The same backhoe model came with 3054C or C4.4 power — we list the sister alternator so you check the engine, not just the model.
  • ✅ Cross-references included — Cat, Perkins and Denso numbers listed so a core or truck-parts counter can confirm it.
  • ✅ ready to ship from our U.S. warehouses — Louisiana and Ohio.
