They represent a triple gearbox (a connection of three gearboxes) and are primarily designed for use in fertilizer spreaders—disc, horizontal, and vertical models, including Jiaolong equipment.
They are classified by power output (from 30 to 160 hp) and can be selected according to the required gear ratio (most common ratios: 1.38, 2.36, 2.47, 2.3, and others).
The cast iron casing ensures resistance to wear, impacts, and high loads, as well as ease of maintenance and a long service life. Thanks to the variety of sizes and parameters, these gearboxes are easily adapted to various types of agricultural machinery.
