Seeding Equipment:

Drills and Seeders: 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 conveying systems 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 the blades for precision mowing lawns and fields.

Material Handling:

Grain Augers and Conveyors: Used to move grain from the harvester to the warehouse or shipping site.

Feed Mixers/Feed Wagons: Drive the mixing auger or spreading device for livestock feed.

Manure Spreaders: Power the manure distribution system.
