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.

Impact of Gear Ratios on Machinery Performance in Agricultural Gearboxes
The gear ratio in agricultural gearboxes plays a crucial role in determining the performance of machinery. It directly affects the relationship between the input and output speeds and torques. Here’s how gear ratios influence machinery performance:
- Speed and Torque Conversion: Gear ratios allow for the conversion of speed and torque between the input and output shafts. Higher gear ratios can reduce output speed while increasing output torque, making it suitable for tasks requiring high power.
- Power and Efficiency: Gear ratios affect the efficiency of power transmission. While reducing the speed through higher gear ratios can increase torque, it’s essential to strike a balance to maintain efficiency. Lower efficiency can lead to energy loss and increased heat generation.
- Task Adaptability: Different agricultural tasks require varying levels of torque and speed. Gear ratios enable machinery to be adaptable to different tasks by providing the necessary torque for heavy-duty activities like plowing or tilling and higher speeds for tasks like transport.
- Optimal Performance: Selecting the appropriate gear ratio ensures that machinery operates within its optimal performance range. It prevents overloading the engine or the gearbox, contributing to smoother operation and reduced wear and tear.
- Productivity and Fuel Efficiency: Proper gear ratios can enhance the overall productivity of agricultural machinery. By optimizing torque and speed, tasks can be completed efficiently, reducing the time and fuel consumption required for operations.
- Consideration of Terrain: Different terrains and field conditions require adjustments in gear ratios. Steep slopes or heavy soil may necessitate lower gear ratios for increased torque, while flat terrain could benefit from higher ratios for faster operation.
- Impact on Components: Gear ratios can influence the load distribution on gearbox components. Higher gear ratios might subject components to increased forces and stresses, potentially affecting their lifespan.
- Operator Comfort: Proper gear ratios contribute to operator comfort by providing the necessary power for smooth operation without straining the machinery. This can lead to reduced operator fatigue and improved safety.
- Personnalisation : Some modern agricultural equipment offers adjustable or variable gear ratios, allowing operators to fine-tune machinery performance based on specific tasks and conditions.
Choosing the right gear ratio for agricultural gearboxes involves considering factors such as the intended task, soil conditions, and equipment specifications. It’s essential to strike a balance between torque and speed to achieve optimal machinery performance and maximize productivity.

Common Signs of Gearbox Wear and Their Solutions
Gearboxes, like any mechanical components, can experience wear over time due to factors such as friction, load, and operating conditions. Recognizing the common signs of gearbox wear is essential for timely maintenance and avoiding potential breakdowns. Here are some signs to watch out for and the solutions to address them:
- Unusual Noises: Grinding, clicking, or whining noises during operation can indicate worn gears or bearings. Inspect the gearbox for damaged teeth or inadequate lubrication. Replace damaged components and ensure proper lubrication.
- Increased Vibration: Excessive vibration suggests misalignment or imbalance within the gearbox. Check for proper alignment and balance the components if necessary. Also, inspect for worn or damaged shafts or bearings.
- Leakage: Oil or lubricant leaks may indicate worn seals or gaskets. Replace seals and gaskets to prevent leakage and ensure adequate lubrication.
- Slipping Gears: Gears slipping out of engagement or difficulty shifting can point to worn or damaged gear teeth. Inspect gears for signs of wear or chipping, and replace as needed.
- Temperature Increase: Abnormal heat generation can result from increased friction due to worn parts. Check lubrication levels and quality, and replace worn bearings or gears causing excess friction.
- Decreased Performance: Reduced power transmission or output efficiency can indicate wear in the gearbox. Inspect gears, bearings, and other components for signs of wear and replace as necessary.
- Excessive Play: Excessive play or backlash in gears can indicate worn gear teeth or bearings. Inspect components for wear, adjust backlash, and replace worn parts.
Addressing gearbox wear requires routine maintenance, including proper lubrication, alignment checks, and regular inspections. Timely replacement of worn or damaged components can extend the gearbox’s lifespan and maintain optimal performance in various applications.
