760-UV Gearbox
Designed for corner systems and lateral move carts where an extended output shaft is required
Growers typically use UMC’s 760-UV gearbox for the most extreme applications where an extended output shaft is required. The gearbox is designed for higher annual hours of operation while handling the heavy loads experienced on corner systems and lateral move carts as well as the most extreme field conditions where wheel rutting is prominent, soil is heavy, and tower weights are higher.
The UMC 760-UV final drive gearbox is our largest and most durable gearbox with an extended output shaft. It features a larger-diameter bull gear than the standard 740 series to handle 20% higher torque. It also features a 2.5″ output shaft to accommodate more overhung load. It is designed for use on center pivots, corners, lateral move/ linear irrigation systems and carts where a 52:1 gear ratio and extended output shaft are standard specifications.
Features and Benefits
- 2.5″ output shaft
- 52:1 gear ratio with a 25° pressure angle
- Unique dual input and output seal design
- 20% more torque capacity than the standard 740
- Bronze gear optional
- Larger input bearings
- Input shaft guard
- External seal protectors for input and output seals
- 11-Bolt mounting pattern
- Full cycle expansion chamber with aluminum cover
- Filled with extreme pressure worm gear oil
- Steel output shaft and ductile iron input shaft
- Tapered roller bearings
- Includes carriage bolts and nuts
- Dual ended input shaft
TNT-2 Gearbox
Designed for applications where the irrigation system may need to be towed
This gearbox is the perfect solution for a towable irrigation system. Growers typically prefer this gearbox over a gearbox with a towable hub. Simply disengage the worm and tow your system to its working location, then re-engage the worm and you are ready to run. The CX coupler is the perfect compliment for the TNT-2 gearbox due to the ability to control coupler disengagement at the gearbox.
The UMC patented TNT-2 final drive gearbox is designed specifically for applications where a center CHINAMFG or lateral move/ linear irrigation system needs to be towed. The gearbox provides the ability to disengage the worm gear and allows users to move systems from 1 area to another without requiring a Towable Hub add on.
Features and Benefits
- 2.25″ output shaft
- 50:1 gear ratio
- Dual input seals with triple lip output seals
- Bronze gear optional
- Input shaft guard
- External seal protectors for input and output seals
- Top oil fill plug
- 11-Bolt mounting pattern
- Full cycle expansion chamber with stainless steel cover
- Filled with extreme pressure worm gear oil
- Steel output shaft and input shaft
- Tapered roller bearings
- Includes carriage bolts and nuts
- Dual ended input shaft
760-UV Bronze Gearbox
Designed for the most extreme conditions where an extended output shaft is required.
Growers typically use The UMC 760-UV bronze gearbox for the most extreme applications where an extended output shaft is required. The gearbox is designed for higher annual hours of operation while handling the heavy loads experienced on corner systems and lateral move carts as well as the most extreme field conditions where wheel rutting is prominent, soil is heavy, and tower weights are higher.
The UMC 760-UV Bronze final drive gearbox is our largest and most durable gearbox with an extended output shaft designed for the most extreme growing conditions. It features a high strength aluminum bronze bull gear and a heat treated steel worm gear giving it a much higher load capacity than the standard 760-UV. Additionally, this gear combination greatly reduces gear wear, extending the useful life of the gearbox. It also features a 2.5″ output shaft to accommodate more overhung load. It is designed for use on center pivots, corners, lateral move/ linear irrigation systems and carts where a 52:1 gear ratio and extended output shaft are standard specifications.
Features and Benefits
- 2.5″ output shaft
- 52:1 gear ratio with a 25° pressure angle
- Unique dual input and output seal design
- Bronze Gear
- Heat Treated Steel Worm Gear
- Larger input bearings
- Input shaft guard
- External seal protectors for input and output seals
- 11-Bolt mounting pattern
- Full cycle expansion chamber with aluminum cover
- Filled with extreme pressure worm gear oil
- Steel output shaft
- Tapered roller bearings
- Includes carriage bolts and nuts
- Dual ended input shaft
- Also Available Assembled in the USA

Is it Better to Repair or Replace a Damaged Gearbox?
Deciding whether to repair or replace a damaged gearbox depends on several factors and considerations:
- Extent of Damage: Assess the severity of the gearbox damage. Minor issues like worn bearings or seals may be repairable, while extensive damage may necessitate a replacement.
- Cost of Repair: Compare the cost of repairing the gearbox to the cost of replacing it with a new or remanufactured unit. In some cases, repairs might be more cost-effective.
- Availability of Parts: Availability of replacement parts for the gearbox can influence the repair option. If parts are hard to find, replacement might be a more viable choice.
- Age and Condition: Consider the age and overall condition of the vehicle. If the vehicle is older and nearing the end of its lifespan, a replacement gearbox might offer better long-term reliability.
- Performance and Efficiency: A new or remanufactured gearbox might offer improved performance and efficiency compared to a repaired one.
- Future Maintenance: Evaluate potential future maintenance needs of both repair and replacement options. A replacement gearbox might come with a warranty and require less frequent maintenance.
- Professional Assessment: Seek advice from a qualified mechanic or technician who can thoroughly assess the gearbox and provide recommendations based on expertise.
Ultimately, the decision to repair or replace a damaged gearbox should be based on a careful evaluation of these factors. It’s recommended to consult with professionals to make an informed choice that best suits your specific situation and budget.
