Buyer and Sourcing Guides
OEM vs Aftermarket Agricultural Machinery Parts
Understand the difference between genuine OEM parts, OEM-reference replacements, and aftermarket replacements.
A genuine OEM part is supplied by or through the original equipment manufacturer. An aftermarket replacement is made by another supplier and may be selected by OEM reference, dimensions, material, or function.
Brand names and OEM numbers on ARGODAYA pages are used for identification and application reference. They do not imply official authorization unless explicitly stated.
