Gear Shaft for John Deere 1175 CE05889 – 13 Tooth Combine Harvester Transmission Component

Product Overview

The Gear Shaft CE05889 (14D / 13-tooth gear component depending on configuration) is a critical transmission element used in the John Deere 1175 combine harvester and related models. It is designed for the internal drivetrain system of the shaker and separation mechanism, helping transfer rotational power smoothly within the harvesting system.

This gear shaft plays a vital role in ensuring stable operation of the straw walker and screening system. Under continuous harvesting conditions, the gearbox components are exposed to heavy vibration, dust, and high torque loads. Therefore, precision manufacturing and material strength are essential for reliable field performance.

Dawopu provides high-quality OEM-compatible agricultural transmission parts designed for durability, accuracy, and long service life in demanding harvesting environments.

Function of the Gear Shaft

The CE05889 gear shaft is responsible for transmitting mechanical power within the combine harvester’s internal separation system.

Its main functions include:

• Driving the shaker and straw walker mechanism
• Ensuring synchronized movement of separation components
• Transferring torque within the gearbox assembly
• Supporting smooth crop separation flow
• Reducing vibration and mechanical stress
• Maintaining stable harvesting performance

A worn or damaged gear shaft can lead to uneven shaking, poor grain separation, increased vibration, and reduced harvesting efficiency.
