Product Description
H142141 Straw Chopper Fixed Flail Knife is stationary cutting blade for straw chopper assembly of John Deere combine harvesters.
**Material features**: Made of high-strength alloy steel with quenching hardening treatment. The cutting edge maintains high hardness and impact toughness, resisting chipping, bending and premature dulling under continuous cutting of corn stalks, wheat straw and crop debris. Precision machined mounting holes ensure stable installation under heavy vibration.
**Product characteristics**: This fixed flail knife works with rotating chopper blades to shear and crush straw and plant residues. Properly shredded straw is evenly distributed over field surface, improving soil organic matter and simplifying subsequent tillage work. Worn, chipped or bent knife results in long uncut stalks, uneven residue spreading, increased chopper load and frequent plugging of chopper housing.
**Compatibility**: Direct aftermarket replacement matching OEM H142141, fully compatible with John Deere combine models:9400,9410,9450,9500,9510,9600,9610,9650,9660,9750STS,9760STS,9860STS,9870STS,CTS,CTS II,S550,S650,S660,S670,S680,S690,S760,S770,S780,S790.
