Product Introduction

The 4YZ-4S series corn harvester is a modern, high-performance agricultural machine designed for efficient mechanized corn harvesting in a variety of soil and climate conditions. This machine combines a powerful powertrain, a reliable chassis, and a sophisticated process design, ensuring stable operation even under intensive use. Particular attention has been paid to ease of maintenance, repairability, and durability, maximizing the equipment's lifespan and maintaining high productivity throughout the harvesting season.

Product Description

The combine harvester is equipped with a powerful 6-cylinder diesel engine producing 220 hp, ensuring high operating speed, excellent productivity, and economical fuel consumption. The use of a closed mechanical axle with a reduction gear increases the reliability of the undercarriage, improves traction, and enhances maneuverability on inclines and uneven terrain.

The wide track, combined with larger wheels, lowers the machine's center of gravity, improving stability when working over large areas and preventing tipping. The cutting platform, equipped with a plate system, neatly separates the corn cobs, minimizing crop loss and damage, and increasing the durability of the cutting tools.

The enlarged elevator ensures a continuous and stable crop flow, eliminating clogs during high-intensity harvesting. A five-drum rubber cleaner effectively cleans cobs without mechanical damage. A large 3 m³ hopper and 2.8 m discharge height reduce the number of unloading stops and significantly increase the overall productivity of the complex.

A modern, sound-insulated, air-tight cabin with ergonomic controls creates a comfortable working environment for the operator. Depending on the crop width and field conditions, the combine harvester is equipped with 550, 580, or 620 model headers, making it versatile for a variety of farms.
