Products Introduction
Irrigation Pivot Gearbox is the core driving transmission component for center pivot irrigation systems. Mounted on tower drive wheels, it works with drive motors to move the irrigation spans in circular operation. Developed for harsh outdoor farm conditions, it serves as a direct aftermarket replacement for original Valley, Zimmatic gearboxes. Standard ratios 50:1 & 52:1 with unified 2.25" output shaft, maximum rated torque up to 10170 Nm. Shock-resistant and heavy-duty, suitable for long-span irrigation equipment running non-stop on farmland.
Product Characteristics
Heavy-Duty Hardened Gear Assembly
Carburized & reinforced thick gear sets resist sudden impact loads. Less prone to gear breakage when starting on muddy ground or slopes, delivering stable performance under sustained heavy loads.
Multi-Layer Sealing for All Weather
Combined multi-lip oil seals and precision housing sealing block silt, rain and dew from the field. Greatly reduce oil leakage risks and withstand wide temperature fluctuations outdoors.
Complete Model Range for Direct Replacement
Full lineup of W series and TNT2 series with various weights. Standardized shaft size simplifies maintenance and bulk spare parts procurement.
Product advantages
High Compatibility & Low Replacement Cost
Mounting flange, shaft dimension and ratio match original European & American gearboxes. Direct on-site fitting without frame modification, minimizing field downtime.
Optimized Heat Dissipation for Continuous Operation
Extended cooling cavity on housing controls temperature rise during long-hour running. Prevent lubricant degradation from overheating, ideal for overnight irrigation on large farms.
Low Maintenance to Cut Operating Expense
Well-designed internal oil circulation extends service intervals of gear oil. Less frequent maintenance and oil changes save farm labor cost.

FAQ
Q:Can I keep operating the gearbox if abnormal noise occurs?
A: Continuous operation is not recommended. Abnormal noise is mostly caused by worn gears or damaged bearings. Further running will lead to severe damage of transmission components. Shut down the machine immediately for inspection and replacement.
Q: What makes model W8760 different?
A:W8760 offers higher torque capacity (10170 Nm), designed for extra-long span, heavily loaded pivots or farms with many slopes. Other models deliver standard 7909 Nm for regular machines.
Q:Is gear oil pre-filled before delivery?
A:Standard products are shipped without lubricant. Fill dedicated gear oil following guidelines after installation before startup.
