Forage Harvester & Silage Chopper Replacement Parts

Self-propelled forage harvesters process up to 400 tons of maize or grass silage per hour, where dull knives or out-of-balance rollers immediately spike diesel burn and degrade feed digestibility. Direct Agri Parts manufactures complete cutterhead-to-spout wear packages: laser-clad tungsten carbide drum knives, carbide-inlaid stationary shearbars, rotary header gathering blades, and G2.5 balanced kernel processors.

Technical & Wholesale Procurement FAQs

Should chopper knives and the stationary shearbar be replaced together before silage season?

For optimal chop quality and fuel economy, always inspect shearbar corner radius whenever installing new chopper knives. A rounded shearbar forces knives to tear rather than shear stalks, increasing horsepower demand by 15%–25%.

Can you supply custom tungsten carbide coating widths for extremely rocky vs. sandy regions?

Yes. Our robotic laser-cladding cells can tailor carbide bead width, granule mesh size, and bevel geometry based on whether your customers harvest rocky grass windrows or fine-sand irrigated maize.
