Frequently Asked Questions
What types of crops are coarse teeth sickle sections best suited for?
Coarse teeth sections are highly recommended for thick-stalked and high-toughness crops such as corn, soybeans, wheat, sunflower, and sorghum. Their wide pitch design ensures strong cutting capability with minimal clogging.
Is this part compatible with my MacDon harvester?
Yes, this coarse teeth blade (OE 286461) is manufactured to 100% original factory specifications and standard hole spacing, allowing a direct, hassle-free replacement on compatible MacDon headers.
What is the advantage of austenitic tempering in these blades?
Austenitic tempering significantly enhances the hardness and wear resistance of the blades. It provides a self-sharpening effect that extends the operational lifespan by 40%–60% compared to standard aftermarket options.
Can these sickle sections operate under high-speed harvesting conditions?
Yes, the low-resistance tooth profile and larger cutting area make them ideal for high-speed headers running at 10–15 mph. They effectively minimize machine vibration and thermal deformation.
How are these replacement parts packaged for delivery?
They are shipped in secure, robust industrial packaging to prevent damage during transit, ensuring they arrive at your location ready for immediate installation.
