How to Determine Your Class

To find the correct freight class for your shipment:

  1. Match packaging to class: fully crated or boxed units typically rate lower than loose or pallet-only pieces. Use the higher class if the attachment ships exposed.
  2. Protect hydraulics on grapples and auger drives—cap quick couplers, secure hoses, and lock cylinders to prevent drips and transit damage.
  3. Palletize heavy steel implements with blocking and edge guards. Example: a 72-in box blade on 4x6 runners, two cross-deck boards, and at least two 2-inch straps.
  4. Mark center of gravity and no-fork zones on wide blades or rakes. Add lift points if needed to keep forks off cutting edges and tines.

Note: All classifications are subject to Item 170. Verify with official NMFC publications for the most current requirements.

Business Value

  • Packaging for the lower class (70) can trim LTL spend by 5–12% versus shipping loose at the higher class.
  • Crated or well-blocked attachments load faster on docks, reducing handling time and the chance of OS&D claims.
  • Clear NMFC alignment lowers reclass risk, minimizing inspection fees and invoice disputes.
  • One listing covers varied implements—auger drives, bale spears, grapples—streamlining quotes and routing for dealers and rental fleets.
