TheAR96872 Radial Piston Pumpis an original John Deere high-pressure hydraulic pump designed for tractors and other agricultural machinery. Featuring a radial piston structure, it provides efficient, durable, and contamination-resistant performance for core hydraulic functions such as steering, lifting, and suspension in tractors.
Key Features:
• High-Pressure Output: Up to 250–350 bar (model-dependent).
• Stable Flow: 20–100 L/min (adjustable based on RPM).
• Durability: Alloy steel pump body with hard-chrome-plated pistons for harsh agricultural environments.
• Broad Compatibility: Fits John Deere 1640–5010 series tractors and select cotton pickers (e.g., 9950–9970).
