Which Version of the MF 187 Manual Do You Need?

Massey Ferguson produced the MF 187 over several years, from the late 1970s through the mid-1980s. There are minor revisions. You must identify your baler’s serial number, typically found on a metal tag attached to the main frame near the flywheel.

  • Early models (SN below 12345): Used a different twine tensioner assembly. Ensure your manual covers early knotter designs.
  • Late models (SN 12346 and above): Feature an improved feed fork timing mechanism and heavier-duty pickup tine retention.

If you purchase a manual labeled "MF 187 Baler (SN 10001 to 20000)," it is likely the comprehensive version covering both eras. Avoid generic "mini-manuals" or "operator cheat sheets"—they lack the critical timing and parts diagrams. Scenario 3: The Needle Frame Hits the Packer

What’s Inside the Massey Ferguson MF 187 Baler Manual?

A genuine factory manual is not a simple pamphlet. It is typically divided into two main sections: the Operator’s Manual and the Service / Repair Manual. Some versions combine both.

Here is a chapter-by-chapter breakdown of what you will find:

The Illustrated Parts Manual (IPB): A Treasure Map

Many owners mistakenly think the parts manual is just for ordering. In reality, the Massey Ferguson MF 187 Baler Parts Manual (often part number 690740M1) is essential for disassembly and reassembly. Each exploded view shows:

  • Exact orientation of bushings, seals, and bearings
  • Order of assembly of the knotter stack
  • Spring locations in the needle yoke mechanism
  • Chain routing for the pickup reel and stuffer

Without these diagrams, a simple knotter rebuild can turn into a puzzle with missing pieces.

Chapter 4 – Field Operation

  • Recommended PTO speed (540 RPM max, never 1000 RPM)
  • Ground speed versus crop condition
  • Windrow placement relative to pickup
  • Starting and stopping techniques to avoid plugging

2. Correct Shear Bolt and Slip Clutch Specs

Using the wrong grade shear bolt on the flywheel or driveline can snap a $10 bolt—or worse, shatter a $800 flywheel. The manual specifies the exact metric or inch-grade bolt hardness, torque values, and slip clutch adjustment (friction disc pressure).

2. Jensales (Aftermarket Reproductions)

Jensales has been reproducing agricultural manuals for decades. They offer clear, bound reproductions of both operator and parts manuals for the MF 187. Their versions often include added troubleshooting indexes.
