What the FX58 is used for
The FX58 was designed for serious silage work, especially custom operators and dairy farms harvesting grass and corn with a single self-propelled chopper. Its horsepower was substantial for its era, and it can still be productive with correctly matched headers and haulage.
Owners now tend to value well-kept examples for their established mechanical design and acquisition cost relative to newer machines. Dealer and parts support should be assessed before purchase because local familiarity with the older FX platform varies widely.
Why the New Holland FX58 stands out
The FX58 was one of New Holland's high-horsepower machines of its era, offering strong crop capacity, pickup widths up to 4.4 m, and corn-processing capability. Its importance is as a durable, capable older FX flagship rather than as a low-maintenance substitute for a newer electronically controlled harvester.
Buying a used New Holland FX58
Buy on condition, not paint or engine hours: examine cutterhead knives, shearbar, knife sharpener, feed rollers, corn-cracker rolls, ejection system, spout liner, driveline, and hydrostatic drive carefully. Check the Caterpillar engine's maintenance history and cooling system, test all header and metal-detection functions, and make sure a nearby dealer or independent specialist can support the serial-number-specific machine.
