8-Notch Disc Harrow Blade 4 Hole Heavy Duty Round Notched Plow Disc Agricultural Machinery Spare Parts
This product is a heavy-duty eight notch four hole circular disc harrow blade, which is a core wear-resistant and vulnerable accessory for agricultural farmland, land preparation, and soil crushing operations. It is widely compatible with various agricultural machinery equipment such as flipping plows, combined land preparation machines, and circular disc harrows. The product strictly follows the original factory standard size and is precision stamped and formed. The center four hole installation position is accurately aligned, and the hole diameter and spacing completely match the original assembly specifications. No additional drilling or polishing is required, and the old parts can be disassembled and directly bolted for installation. It is easy to replace and has strong universality.
This product is made of high-strength and high-quality wear-resistant alloy steel plate forged in one piece, and treated with professional quenching and tempering heat treatment process. The internal structure of the steel is dense and tough, with both high hardness and excellent impact resistance. The edge eight notch arc-shaped blade design provides stronger penetration into the soil, and the crushing, stubble breaking, and weeding effects far exceed those of smooth circular disc harrows. It can efficiently crush hard soil blocks, cut off straw and weeds, loosen deep soil, and greatly improve the quality and efficiency of land preparation operations.
When working in the field, it can effectively resist the friction of sand and gravel, the squeezing and impact of soil layers, the cutting edge is long-lasting and sharp, not easy to passivate, the disc surface is not easy to warp or deform, and not easy to crack or collapse. Its service life is much longer than that of ordinary cold-rolled steel plate harrows.
The surface of the product is treated with a black anti-corrosion and anti rust coating, which has strong adhesion, moisture resistance, and salt alkali corrosion resistance. It is not easy to peel off paint, rust, or oxidize and age after long-term operation in muddy farmland and straw fields outdoors. The smooth surface, combined with the notch cutting edge, reduces the resistance to entering the soil, effectively reduces the load on agricultural machinery, reduces fuel consumption, and stabilizes the overall operating posture, making the plowing of farmland even and smooth.
