The industry-leading Valley gearbox is life-tested and quality checked throughout the process to ensure we are constructing the most reliable and structurally sound gearbox available.

Valley Gearbox Features

Superior design: Three times the life of competitive gearboxes, based on independent tests.
Greater torque capacity: Bull gear delivers 20% higher torque capacity, based on independent tests.
Built-to-last: Longer output shaft increases mud and crop clearance, reducing chance of seal damage.
Minimizes bearing loads: Special offset rims position tire close to the gearbox to minimize bearing loads for longer life.
Highest load rating: Input and output bearings are American made and case hardened, resulting in the industry's highest load rating.
Handles extreme conditions: Gearbox housing made to handle high-stress areas and extreme operating conditions.
Additional load capabilities: Bronze bull gear option provides additional load capabilities with hardened steel worm for extreme operating conditions or extended life under less-severe conditions.

Valley Gearbox Specifications

Large-capacity rubber diaphragm: Expands with heat and pressure to minimize water condensation.
Input and output bearings: Case hardened to provide the highest quality and highest load rating available in the industry.
Worm gear: High-strength ductile iron provides significantly longer wear life than steel when combined with a cast iron bull gear.
Tooth design: Industry exclusive 25° tooth angle provides 40% longer life and better reliability in tough conditions compared to normal 14 1/2° tooth designs.
Largest bull gear neck and keyway: Provides strength in critical load-bearing area.
Expansion chamber: Cap made of corrosion-resistant cast aluminum; rubber diaphragm allows oil to expand and contract during operation. Vented cap prevents pressure buildup and prevents seals from leaking.
Threaded endcap: Allows accurate bearing preload to increase bearing life.
52:1 gear ratio: Fully recessed tooth design keeps oil between engaged gears.
Bull gear: High-strength cast iron provides the highest load capacity and longest life in the industry. Optional bronze gear is available for extreme conditions.
Multi-viscosity gearbox oil: Exceeds 85w140 GL5 oil for long gear wear under extreme load conditions.
