Ag Growth International (AGI) has introduced two new diesel-powered grain handling tools. The STX3 auger and UCX4 conveyor are additions to the company’s portable grain handling lineup and are available in limited release now with full production anticipated for 2026.
“AGI is excited to bring these diesel-driven products to market,” said Paul Brisebois, AGI senior vice president, North American farm and global portables. “The STX3 and UCX4 are power-pair innovations, engineered to meet the demanding requirements of grain farmers in Canada and the United States with a focus on uptime, fuel savings, and performance.”
STX3 Auger
The STX3 is the first diesel-powered direct-drive portable truck loading auger on the market, replacing traditional belt drives. The auger features a 56-hp Kohler diesel engine for better torque and a belt-free direct drive system for consistent mechanical PTO performance.
Key features include:
- Open discharge spout
- Manual clutch engagement
- Heavy-duty gearboxes and solid drive shaft
- High-clearance intake hopper with triple flighting
- All-wheel-drive hydraulic mover kit
- Wear Edge technology, sealed top end, and LED work lights
“This auger isn’t just diesel-powered — it’s farmer-driven,” said Kent Woods, AGI director of global product management. “The STX3 is great for farms with multiple bins and trucks. It gives farmers what they are looking for in an auger: high capacity, enhanced durability, and diesel efficiency.”
The STX3 diesel auger is available under the following brands: AGI Westfield (STX3), AGI (XTA3), and GrainMaxx (GTX3).
UCX4 Conveyor
The UCX4 conveyor delivers up to 10,500 bushels per hour with a 24-hp Kohler diesel engine. In AGI field tests, the UCX4 can use up to 48% less fuel than comparable gas-powered models.
Key features include:
- Bell housing electric clutch
- Direct mount hydraulic pump
- Heads-up digital display
- 1500W block heater and 1000CCA battery
- Overhauled engine mount
- Lower profile collapsible hopper
AGI
“We’ve engineered the UCX4 from the ground up to meet the real-world needs of large farm operations,” Woods said. “This conveyor moves large volumes of commodities that require gentler handling, like seed grain, canola, and other pulses. Every detail is designed to maximize uptime and simplify operation in harsh conditions.”
The UCX4 diesel conveyor is available under the following brands: AGI Batco, AGI Westfield, and AGI GrainMaxx.
