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.

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

Precise Control of Irrigation Equipment with Gearboxes
Irrigation gearboxes play a crucial role in ensuring precise control of irrigation equipment, especially in pivot and linear irrigation systems. Here's how they achieve this:
- Ratio and Speed Control: Gearboxes are designed to provide precise control over the rotational speed and direction of motion. This allows farmers to adjust the speed at which the irrigation equipment moves along the designated path.
- Adjustability: Gearboxes often come with adjustable settings that enable farmers to customize the angle and radius of coverage. In pivot irrigation, for instance, gearboxes control the pivot point, allowing for varying degrees of rotation and precise positioning of sprinklers.
- Positional Accuracy: Gearboxes ensure accurate positioning of irrigation equipment by translating the rotational motion of the motor into linear movement along a specific path. This accuracy is essential to evenly distribute water across the field and avoid over-watering or under-watering.
- Repeatability: Gearboxes provide consistent and repeatable movement, ensuring that irrigation equipment follows the same path with each cycle. This repeatability is vital for maintaining uniform water distribution and optimizing crop growth.
- Integration with Control Systems: Many modern irrigation systems incorporate advanced control systems that can precisely adjust the gearbox's settings based on factors such as soil moisture levels, weather conditions, and specific crop requirements.
- Automation: Gearboxes can be integrated into automated irrigation systems that can be programmed to start, stop, and adjust movement patterns automatically. This level of automation ensures precise and efficient water distribution without the need for constant manual intervention.
By providing the means to control speed, angle, and direction, irrigation gearboxes enable farmers to achieve accurate and efficient water distribution, resulting in healthier crops and optimized water usage.
Disadvantages and Limitations of Using Irrigation Gear Systems
While irrigation gear systems offer numerous benefits, they also come with some disadvantages and limitations:
- Cost: Irrigation gear systems can be relatively expensive to install and maintain, especially when compared to manual irrigation methods. The initial investment includes the cost of gearboxes, motors, pumps, and other associated components.
- Maintenance: Regular maintenance is essential to keep irrigation gear systems functioning properly. Gearboxes and other mechanical components require periodic checks, lubrication, and potential repairs, which can add to maintenance costs and downtime.
- Complexity: The complexity of irrigation gear systems can pose challenges for farmers who are not familiar with mechanical systems. Troubleshooting issues or making adjustments might require technical expertise.
- Dependence on Power: Many irrigation gear systems rely on electricity to operate, which can be a limitation in areas with unreliable power sources or during power outages.
- Environmental Impact: Depending on the energy source used, irrigation gear systems can have an environmental impact, especially if they are powered by non-renewable resources.
- Site Limitations: The suitability of irrigation gear systems depends on the layout and terrain of the field. Steep slopes, rocky terrain, or irregular field shapes might limit the effectiveness of these systems.
Despite these limitations, proper planning, maintenance, and operational considerations can help mitigate these challenges, allowing farmers to harness the benefits of irrigation gear systems while addressing their drawbacks.
Variations in Irrigation Gearbox Designs for Specific Irrigation Methods
Irrigation gearbox designs can vary based on the specific irrigation methods they are intended to be used with. Different irrigation techniques require different gearboxes to optimize water distribution. Here are some examples of variations in irrigation gearbox designs:
- Pivot Irrigation: Pivot irrigation systems use linear move or center pivot systems to distribute water in a circular pattern. Gearboxes for pivot irrigation often have a high degree of angular adjustability to accommodate the circular motion. They may also feature specialized seals and coatings to withstand exposure to water and environmental factors.
- Linear Irrigation: Linear irrigation involves moving the water distribution equipment along a straight line. Gearboxes for linear irrigation systems need to provide smooth and precise linear motion. They may incorporate linear actuators or guides to ensure accurate movement.
- Drip Irrigation: Drip irrigation delivers water directly to the plant root zone. Gearboxes for drip irrigation may be part of valve control systems that regulate the water flow to individual drip lines. These gearboxes need to be compact and efficient in controlling the flow rate.
- Sprinkler Irrigation: Sprinkler systems disperse water over the cultivated area in a spray pattern. Gearboxes for sprinkler irrigation may be used in the rotating heads of sprinklers. They need to provide reliable rotation and positioning for even water coverage.
- Subsurface Irrigation: Subsurface irrigation delivers water below the soil surface. Gearboxes for subsurface irrigation may be used in valve systems controlling the water release from underground pipes. They require durability and resistance to soil and moisture.
These variations in irrigation gearbox designs reflect the diverse needs of different irrigation methods. Customized gearbox designs help ensure efficient and effective water distribution for various agricultural and landscaping applications.
