Information

Every combine harvester contains two vertical conveying lines that almost no one notices until they clog: one is the grain elevator that lifts clean grain into the grain tank, and the other is the tailings elevator that returns unthreshed heads back to the threshing unit for a second pass. Dealers and repair shops often confuse

In the undercarriage travel system of a tracked combine harvester, the Tensioner Arm and the Tensioner Wheel Assembly are two components that are often confused with each other. They are mounted side by side on the track frame, are usually replaced at the same time, and many dealers list them together in the same RFQ

When combine harvesters operate in the field, their core components endure continuous high loads, impact, and wear, making them one of the most intensively worked machines in agriculture. The service life of these components determines the harvester’s working window, and high-quality parts can last through an entire harvest season. This is why we recommend choosing

The idler wheel of a combine harvester is installed at the front end of the track running system (opposite the drive sprocket). By guiding the track chain, maintaining track tension, controlling deviation, and bearing a considerable portion of the machine’s weight, it is one of the important harvester undercarriage parts and also a common wear

The drive sprocket of a combine harvester is installed at the output end of the gearbox. Through its tooth profile, it engages with the track and converts engine power into tractive force for travel. Whether the harvester can move forward, turn, and climb slopes in muddy paddy fields depends entirely on the drive sprocket. Why

In the heat treatment process for agricultural machinery undercarriage parts such as drive sprockets, track rollers, and gears, quenching is the critical step that determines wear resistance and service life. Different quenching methods vary in heating depth, hardened layer distribution, and applicable scenarios – which is why we often see harvester parts that look identical

A combine harvester auger (Auger / Conveyor Auger) is a spiral conveying device consisting of a shaft with spiral flights. When the harvester is operating, the shaft rotates → the spiral flights push grain, crop material, or other materials → the material moves in a transverse or longitudinal direction to different working stages. Because augers

Combine harvesters consist not only of metal parts. Rubber parts, plastic parts, seals, flexible components, and other non-metallic parts play a vital role in dust protection, sealing, vibration damping, crop and material conveying, machine protection, friction reduction, and operator comfort. Maikeyier supplies premium Combine Harvester Rubber Plastic Parts to agricultural machinery importers, dealers, wholesalers, and

A combine harvester is assembled from thousands of individual components. Beyond the core assemblies such as the engine, hydraulic system, header, and threshing system, a large number of hardware connectors, fasteners, supports, and mounting parts are required to maintain stable machine operation. The choice of harvester hardware parts affects assembly quality, machine stability, vibration resistance,

A combine harvester is a complex agricultural machine composed of hundreds of individual components – a considerable portion of which are sheet metal parts. From engine hoods and side panels to protective guards and access doors, sheet metal components serve as the “first line of defense” that protects internal precision systems, ensures operator safety, and
