AH227588 Steering Cylinder Rod for John Deere STS 9470 Combine Harvester

OEM Replacement Steering Cylinder Rod Assembly for Combine Steering Systems

Product Overview

The AH227588 Steering Cylinder Rod is a critical component of the hydraulic steering system used on the John Deere STS 9470 combine harvester. The rod transfers hydraulic force from the steering cylinder to the steering linkage, enabling precise wheel movement and reliable steering control during harvesting operations. According to replacement-part references, the rod is approximately 40 mm in diameter and 878 mm in overall length, designed specifically for the STS 9470 steering system.

Because combine harvesters operate in demanding field environments, steering cylinder rods must withstand heavy loads, vibration, shock, mud, dust, and continuous steering cycles. Precision machining, high-strength materials, and durable surface finishes are essential for ensuring long service life and dependable performance.

At Dawopu, we manufacture OEM-quality replacement steering cylinder rods engineered to meet or exceed original equipment specifications for agricultural machinery applications.
