Combine harvesters operate under some of the most demanding conditions in agricultural machinery. Continuous operation during harvest season, heavy vibration, dust exposure, impact loads, and high precision requirements all place strict demands on hydraulic components.
Our Custom Combine Harvester Hydraulic Cylinders are engineered specifically for header control, lifting systems, auger positioning, and leveling mechanisms, ensuring stable performance and accurate motion control in the field.
Typical Applications
Header Lift Cylinder
Used to control the cutting height of the header.
This is one of the most critical cylinders in a combine harvester because cutting accuracy directly affects harvesting efficiency.
Key Features:
Smooth and stable extension/retraction
High positioning accuracy
Low internal leakage
Cushioning design to reduce impact during lowering
Strong resistance to vibration and shock
Reel Adjustment Cylinder
Controls reel height and angle to adapt to different crop conditions.
Key Features:
Fast response
Stable motion control
High sealing reliability in dusty environments
Optimized structure for frequent operation
Unloading Auger Cylinder
Responsible for folding and positioning the unloading system.
Key Features:
High structural strength
Strong anti-bending performance
Reliable operation under heavy loads
Corrosion-resistant surface treatment
Leveling and Chassis Adjustment Cylinder
Used in advanced combine models for slope compensation and chassis balance.
Key Features:
High-pressure design
Reinforced piston and rod structure
Stable performance under continuous load changes
Long service life in complex terrain
Technical Requirements for Combine Harvester Cylinders
Compared with standard agricultural cylinders, combine harvester cylinders require:
Higher machining precision
Better sealing performance against dust and crop residue
Stronger rod and piston design for dynamic loads
Superior anti-corrosion treatment
Stable operation during long working hours
Precision and durability are essential to ensure consistent header control and reduce mechanical wear.
