Last updated: April 2026 dataAgricultural and roadside mowers designed for tractor mounting or towing — including rotary cutter types (8433200020), non-rotary tractor-drawn mowers (8433200040), and cutter bars (8433200060) — are the core products here, serving hay production, right-of-way maintenance, and large-acreage cutting operations. Mexico leads US imports under this heading, with Germany and Canada also significant, reflecting both North American agricultural supply chains and European precision-mowing technology. The critical classification boundary is between rotary cutter types and other tractor-drawn mowers, as the two carry separate 10-digit lines.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Rotary cutter-type mowers (8433200020) use one or more horizontally spinning blades or flails driven by the tractor's PTO to cut heavy vegetation, brush, or crop residue. Other tractor-drawn or mounted mowers (8433200040) use disc, drum, or sickle-bar cutting mechanisms. The cutting mechanism — not the mounting method — determines which line applies.
Yes. Cutter bars for tractor mounting are explicitly named in heading 843320 and are classified under 8433200060 when imported as standalone components. If imported as part of a complete mower assembly, the complete machine governs classification.
