UMC TNT-2 Gearbox is 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.

Engineer Overseeing Pivot Installation on a Large Farm
As the irrigation systems engineer for a commercial maize farm in Kansas, I selected the TNT Gearbox to integrate with the main tower of our newly-installed centre-pivot unit. The mechanism’s 50:1 gear-ratio and dedicated seal-protector design ensure that during long daily runs under high loads the drive remains reliable. With its 2.25-inch output shaft, the gearbox fits seamlessly with our standard wheel hub hardware and supports efficient installation and service maintenance. The gearbox allowed us to standardise across multiple towers, minimise downtime and ensure the system’s operational integrity across the full cropping season.

Field Service Technician Maintaining Towable Irrigation Carts
In a remote irrigation project in South Australia, my role as field service technician required me to maintain towable lateral-move systems. We opted for the TNT Gearbox because it offers a disengage-able worm gear function specifically designed for towable applications — enabling the cart to be moved without disengaging the drive manually each time. This capability significantly reduced labour and machine wear during repositioning phases. The robust cast-iron construction and protective seals meant system downtime was minimised even under dusty, high-load conditions.

Agricultural Consultant Advising on Heavy-Duty Corner Systems
As an agricultural systems consultant working with large-scale cotton operations in Brazil, I recommended deploying the TNT Gearbox in their corner-arm rigs and large-span pivots because the gearbox is purpose-built for heavy-load towers and large-diameter wheels. Its universal mount pattern and dual-ended input shaft simplify retrofits of existing machines. From my perspective, the gearbox’s capacity to handle higher torque and extended service intervals makes it an excellent fit when advising clients on long-term investment in irrigation infrastructure; the upfront cost is balanced by fewer service calls and reliable performance.


FAQ

What is the typical installation process for the TNT Gearbox?
Installation involves mounting the unit using the universal bolt pattern, aligning the output shaft with the wheel hub, filling with the recommended extreme-pressure gear oil, and verifying seal integrity before commissioning.

What warranty or technical support is offered?
Irritech partners with the gearbox manufacturer’s global network to provide technical support. The gearbox comes with the manufacturer’s standard warranty for workmanship and materials; for specific conditions consult your local distributor.

Does the TNT Gearbox work with all brands of centre-pivot systems?
Yes — the gearbox is designed with a universal mounting pattern and dual-ended input shaft to fit a wide range of pivot and lateral-move systems across major irrigation brands.

What is the lead-time for supply of the TNT Gearbox?
Typical lead-times depend on the region and distributor inventory levels but are generally aligned with standard heavy-equipment supply chains — please contact your local Irritech authorised dealer for current availability.

How is data or operational feedback handled with the gearbox?
While the gearbox itself is purely mechanical, Irritech systems integrate with control panels equipped for monitoring tower operation. For gearbox-specific service data, periodic inspections and oil-analysis are recommended to ensure reliable performance.
