NH Controller / Guide 48058666 for New Holland Header Mowing System

 The 48058666 NH controller is an original-style spare part for New Holland combine harvester header/mowing system assemblies. It is a small but important wear or guide component used in the cutting/header system, helping maintain correct positioning and smooth operation of related moving parts.


Key Specifications

  • Product Name: NH Controller/Guide
  • Part Number: 48058666
  • Reference: 880091836
  • Category: Combine harvester parts / Mowing system parts
  • Application: New Holland grain headers/header cutting system
  • Promotional Price: €4.50 per unit
  • Regular Price: €6.00 per unit
  • Availability: Promotion item

Build & Design

The part has a compact black molded body with two mounting holes and a raised central guide area. Its shape suggests it is designed to be bolted into place and used as a stabilizing, guiding, or control component within the header mechanism.

The design is simple but functional, with rounded edges and a sturdy structure suitable for agricultural machinery use.


Compatibility

The listing states that it fits several New Holland header models, including:

  • 3050-30FT grain combine
  • 760CG grain headers: 16 ft, 18 ft, 20 ft, 22 ft, 25 ft, 28 ft, 30 ft, 35 ft, 41 ft

Because New Holland header assemblies can vary by production year and configuration, compatibility should be confirmed using the original part number 48058666 before purchase.


Performance

This part helps support the proper operation of the header/mowing system. A worn or damaged guide/controller can contribute to:

  • Excessive play in the mechanism
  • Poor alignment
  • Increased wear on neighboring parts
  • Reduced cutting system smoothness

Replacing a small worn component like this can help prevent larger wear issues in the header assembly.


Installation

Installation should be straightforward, as the part appears to mount with two fasteners. During replacement, it is worth checking surrounding components for wear, especially if the old part failed because of misalignment, vibration, or loose hardware.


Value for Money

At the promotional price of €4.50, this is an inexpensive replacement part. Considering its role in the header system, it is a practical maintenance item and worth keeping as a spare if the machine uses this component.


Pros

  • Affordable promotional price
  • Fits multiple New Holland 760CG header sizes
  • Simple bolt-on design
  • Useful for header/mowing system maintenance
  • Helps reduce wear and improve alignment

Cons

  • The exact function should be confirmed from the parts catalogue
  • Compatibility depends on the header model and year
  • A small part, but an incorrect fitment can affect performance

Final Verdict

The NH 48058666 controller/guide is a small but useful spare part for New Holland combine header systems. Its low cost, simple design, and wide compatibility make it a practical replacement item for maintaining smooth and reliable header operation.
