Standard ratios 50:1 & 52:1 with unified 2.25" output shaft, rated torque ranges from 7909 Nm to 10170 Nm. Optimized for North American farm conditions including muddy terrain, slopes and wide temperature fluctuation, it fits renovation and new assembly of short and long-span Valley irrigation systems.
Product Characteristics
OEM Standard Mounting for Modification-Free Replacement
Flange hole layout, output shaft dimension and input interface fully match Valley center pivot equipment. Direct on-site fitting without frame cutting or reaming, minimizing field downtime.
High-Strength Ductile Iron Housing
Integrally cast housing delivers outstanding rigidity, resisting deformation under heavy shock loads and maintaining stable gear meshing accuracy to prevent housing crack during long bumpy operation.

FAQ
Q:Is this gearbox only compatible with Valley pivots?
A:It is primarily designed as replacement for Valley center pivot systems. It also fits several other irrigation brands with identical mounting standards. Confirm flange dimension and ratio before ordering.
Q:Can I keep operating the gearbox if abnormal noise occurs?
A:Continuous operation is not advised. Abnormal noise indicates worn gears or damaged bearings. Further operation will lead to catastrophic failure; shut down immediately for inspection.
Q:How frequently should gear oil be replaced?
A:Replace oil after each irrigation season. For year-round continuous heavy operation, change oil every 6 months to avoid deterioration and internal abrasion.
