Equipped with GPS and factory autopilot, the Valtra A84S tractor stands out in the 80 to 100 horsepower segment as a complete option that combines the power of AGCO Power mechanics with the precision of digital agriculture.
In the competitive medium-power tractor market, the Valtra A84S tractor emerges as a modern and robust solution for farmers seeking greater efficiency and technology. Part of the renewed A4S Series, this 89-horsepower model draws attention for offering, as a factory item, a technology package that was previously restricted to larger machines, including autopilot and GPS from Trimble.
This combination of strength and intelligence places the Valtra A84S tractor in a prominent position, promising not only excellent performance in the field but also a more economical and precise operation. It is proof that precision agriculture is becoming increasingly accessible, providing farmers with a machine ready to face the challenges of modern farming.
Engine and Transmission: The AGCO Power Heart

The performance of the Valtra A84S tractor is guaranteed by the reliable AGCO Power 3-cylinder engine with turbo and intercooler, delivering 89 horsepower. This engine is known for its high torque at low RPMs, which translates into power for pulling heavy implements and fuel economy.

Brazil is already the largest food supplier to China and is now advancing in the trade of corn and sorghum with the Chinese. The ambassador highlights that the two countries have strong agricultural complementarity and ample space to grow together.
The transmission is another strong point. The model comes equipped with the PowerShift 12×12 (12 forward and 12 reverse gears), which features the PowerShuttle electro-hydraulic reversal system. This allows the operator to change the tractor’s direction quickly and smoothly without having to use the clutch pedal, greatly increasing agility in maneuvers and operations that require repetitive movements.
Factory Technology: GPS and Trimble Autopilot

The biggest differential of the Valtra A84S tractor is undoubtedly the embedded technology. It can come equipped from the factory with:
- Electric Autopilot: Reduces operator fatigue and ensures that the passes in the field are perfectly straight, avoiding overlaps and gaps.
- Trimble GPS: Integrated into the tractor’s system, the GPS receiver offers high positioning accuracy, which is essential for planting, spraying, and harvesting.
This combination allows for much more efficient work, optimizing input usage, saving fuel, and enabling the operator to focus on the quality of the implement operation, not just on steering the tractor.
Cabin and Operation: Comfort and Ergonomics
Valtra is known for the comfort of its cabins, and the A84S is no different. The interior space is spacious, with excellent visibility and well-crafted finishes. Most controls are ergonomically positioned on the side console, facilitating operator access.
The instrument panel is digital and complete, providing all necessary information about the machine’s operation. The air conditioning and adjustable seat ensure comfort even after long hours of work.
Robustness and Lifting Capacity
True to the brand’s tradition, the Valtra A84S tractor is a heavy and well-ballasted machine, ensuring greater traction capacity and stability. The hydraulic system is also impressive, with a lifting capacity of 3,000 kg at the three-point hitch, allowing it to work with a wide range of implements. Additionally, it features external hydraulic lift controls on the rear fenders, a detail that greatly facilitates equipment coupling.
With a price that may vary depending on the configuration and the region, the complete version of the Valtra A84S tractor with autopilot and GPS is positioned as a high-value investment, delivering a machine ready to produce with maximum efficiency.
