Case IH 87726623 Straw Spreader Blade Curved LH
OEM Left-Hand Curved Straw Spreader Blade for Case IH Combines
Product Overview
The Case IH 87726623 Straw Spreader Blade Curved LH is a high-performance replacement blade designed for the straw spreading system of Case IH combine harvesters. The left-hand (LH) curved design ensures even distribution of straw and crop residue across the full cutting width of the header, helping improve residue management and field conditions after harvest.
Straw spreader blades operate at high rotational speeds and are exposed to constant impact from straw, chaff, dust, and debris. Therefore, they require excellent wear resistance, impact strength, and fatigue performance.
At Dawopu, we manufacture OEM-quality straw spreader blades using premium wear-resistant alloy steel and advanced heat-treatment processes to ensure maximum durability and consistent spreading performance.
