Vérin hydraulique de liaison supérieure pour herses à disques Cat 3

A Cat 3 tractor top link hydraulic cylinder is an essential component used in agricultural machinery, particularly for disc harrows and other three-point hitch attachments. This hydraulic cylinder top link replaces the traditional manual top link, allowing for precise and effortless adjustment of the angle and tilt of the implement attached to the tractor. It connects the tractor's top link mounting point to the implement, enabling the operator to control its position hydraulically from the tractor's cab.

Designed for Category 3 hitch systems, which are commonly used on larger tractors, this hydraulic top link cylinder enhances efficiency in soil preparation by ensuring that the disc harrow operates at the optimal angle for cutting, leveling, and breaking up soil. Constructed from durable, heavy-duty materials, it can withstand the stresses of tough field conditions. Additionally, it features standardized fittings for compatibility with most tractors and hydraulic systems.

Features of Cat 3 Top Link Hydraulic Cylinder for Disc Harrows

• Double-Acting Hydraulic Design: The Cat 3 top link hydraulic cylinder operates as a double-acting system, allowing precise extension and retraction. This enables dynamic adjustments of the disc harrow’s angle and depth from the tractor cab, enhancing tillage efficiency across varying soil conditions.
• High-Pressure Capacity: Built to withstand up to 3,000 PSI, the hydraulic cylinder top link ensures reliable performance under heavy loads. Its robust construction supports the demanding forces of disc harrows, maintaining consistent operation during intensive tasks on large-scale agricultural fields.
• Durable Construction: Featuring a chrome-plated rod and high-quality seals, the hydraulic top link cylinder resists corrosion and wear. Its heavy-duty steel body is designed for longevity, ensuring dependable performance in harsh environments, reducing maintenance needs, and extending service life.
• Adjustable Stroke Length: With a stroke length typically ranging from 4 to 100 inches, the cylinder provides a large adjustment range. This flexibility allows precise positioning of the disc harrow, optimizing soil penetration and implement performance.
• Drift Prevention Mechanism: Equipped with double-piloted check valves, the top link hydraulic cylinder locks the hydraulic fluid to prevent implement drift. This ensures the disc harrow maintains its set position during operation, improving accuracy and reducing operator adjustments in uneven terrain.
• Category 3 Compatibility: Designed for Cat 3 three-point hitches, it suits tractors with 80-225 horsepower. The top link cylinder’s 0.5-2 inch pins ensure secure attachment to heavy implements like disc harrows, supporting efficient operation on large farms.

Proper Maintenance of Top Link Hydraulic Cylinder for Disc Harrow

1. Regular Inspection for Leaks: Check the top link hydraulic cylinder monthly for hydraulic fluid leaks around seals and fittings. Leaks can reduce performance and damage components. Wipe down the cylinder, inspect for oil residue, and replace worn seals promptly to ensure efficient operation and prevent contamination.
2. Clean the Cylinder Surface: After each use, remove dirt, debris, and crop residue from the hydraulic top link cylinder's exterior using a soft cloth or brush. This prevents corrosion and protects the chrome-plated rod, extending the cylinder’s lifespan in harsh agricultural environments.
3. Lubricate Moving Parts: Apply high-quality grease to the hydraulic cylinder top link's pivot points and fittings every 50 hours of operation. Proper lubrication reduces friction, prevents wear, and ensures smooth movement, maintaining the cylinder’s precision during disc harrow angle adjustments.
4. Check Hydraulic Fluid Levels: Monitor the tractor's hydraulic reservoir fluid level biweekly, ensuring it meets manufacturer specifications. Use only recommended hydraulic fluid types to avoid contamination, which can cause valve malfunctions or reduced hydraulic cylinder top link responsiveness during operation.
5. Inspect Hoses and Connections: Examine hydraulic hoses and couplings quarterly for cracks, abrasions, or loose connections. Replace damaged hoses immediately to prevent pressure loss or system failure, ensuring consistent performance when adjusting the disc harrow in the field.
6. Store Properly When Not in Use: During off-season storage, retract the top link hydraulic cylinder fully and store the tractor in a dry, covered area. Apply a protective coating to the rod to prevent rust, ensuring the cylinder remains functional for the next planting season.
