Wholesale 118344 / 47687886 DEDO DUPLO MACDON Knife Guiard | Finger for CNH Combine | Aftermarket Manufacturers, Factories

This double finger knife guard is a core wear component on the cutterbar assembly. Farmers and service workshops rely on this part to support reciprocating sickle sections, hold crop material steady during cutting and avoid straw wrapping around the cutter system. The Dedo Duplo dual-tip design delivers more stable crop control compared with single finger guards, especially when harvesting heavy, tangled crops such as canola and alfalfa.
We manufacture this guard using hot forged medium alloy steel, far stronger than simple cast alternatives. Critical contact tips receive local induction hardening to extend service life in high-load field work. The base mounting holes follow original OEM dimensions precisely, allowing direct bolt-on replacement without drilling or modification during header maintenance.
