Blade Set New

6-piece piston knife blade set, great quality, specially designed for Massey Ferguson MF1839 and MF1840 series square hay balers. Made of high-grade wear-resistant alloy steel with precision sharpened edges, delivers clean and uniform cutting performance for hay and straw during bale compression. Installed on the baler plunger, works with the fixed cutting edge to shear forage materials and ensure neat bale end face and consistent bale forming quality. The blade edges are severely worn, chipped or rolled, causing uneven cutting, ragged bale ends and increased compression resistance. Individual blades are deformed, cracked or have damaged mounting holes, leading to unstable installation and risk of falling off during high-speed operation. Cutting height inconsistency occurs after partial blade replacement, resulting in poor shearing effect and accelerated wear of the whole piston mechanism. Restores clean and efficient shearing performance, ensures neat and uniform bale end face, and stabilizes overall bale forming quality. Full set replacement guarantees consistent blade height and cutting clearance, reduces abnormal wear and extends the service life of the piston assembly. Original Shenfa quality provides excellent wear resistance, reduces frequent replacement frequency and lowers equipment downtime during harvest season.
