Farm Center Gear Box Pivot Sprinkler Irrigation Greenhouse System Special Gearbox for Valley Pivots
Product Description
Input and output bearings: American made and case hardened; Industrys highest load rating for longer life
Gearbox housing: More material in high-stress areas to handle extreme operating conditions
Bronze bull gear option: Provides additional load capabilities with hardened steel worm for extreme operating conditions or extended life under less severe conditions
Large-capacity rubber diaphragm: Expands with heat and pressure to minimize water condensation.
Input and output bearings: American made and 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: For 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.
50:1 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.

Gearboxes in Agricultural Machinery
Tillage and Soil Preparation:
Rotary Tillers/Rotary Tillers: The gearbox drives the rotating teeth that break up and aerate the soil.
Tillage Machines: In some active tillage machines, the gearbox powers the soil gripping components.
Seeding Equipment:
Drills and Planters: The gearbox precisely controls the metering mechanisms for seed and fertilizer, ensuring accurate spacing and application rates.
Fertilizer Spreaders: Drive the rotating discs or augers for even distribution.
Harvesting Equipment:
Combine Harvesters: Drive the cutting knives, threshing drums, cleaning fans, and the delivery system for grain, corn, or soybeans.
Hay Balers: Power the pick-up mechanism, compression chamber, and knotting system.
Forage Harvesters: Drive the cutting, chopping, and blowing units for silage production.
Root Crop Harvesters: Used to dig, separate and convey crops such as potatoes.
Mowing and Vegetation Management:
Rotary Cutter/Brush Sweeper: The transmission drives the vertical shaft that rotates the cutting blades for clearing dense brush.
Flail Mower/Stalk Chopper: Transmits power to the horizontal rotor that shreds crop residue.
Precision Mower: Drives blades for precision mowing lawns and fields.
Material Handling:
Grain Augers and Conveyors: Used to move grain from the harvester to storage or transportation sites.
Feed Mixers/Feed Wagons: Drive mixing augers or spreading devices for livestock feed.
Manure Spreaders: Power manure distribution systems.
Specialty Farm Equipment:
Diggers: The transmission connects the power take-off (PTO) to the vertical auger.
Sprayers: Power pumps or boom folding mechanisms.
Snowblower: drives the auger and impeller to remove snow.
