TRANSMISSIONS OVERVIEW
The Ursus 3512 tractor features an 8-speed transmission coupled with an optional 12-speed creeper gear, enhancing its versatility for varying field conditions. The 12-speed creeper gear allows for precise low-speed operations, making it ideal for tasks such as tilling or planting in tight spaces. However, operators may experience a steeper learning curve managing the transition between gears due to the increased complexity of the transmission system.

TRANSMISSION 1
The Ursus 3512 tractor features an 8-speed forward and 2-speed reverse gearbox, allowing for enhanced versatility and better torque management across varying field conditions. The 8 forward gears facilitate optimized speed and power delivery for both heavy-duty and light tasks, while the 2 reverse gears provide efficient maneuverability in confined spaces. However, the limited reverse gearing may pose challenges in operations requiring frequent directional changes in tight environments.

| Description | With 14.9-28 rear tires |
TRANSMISSION 2
The Ursus 3512 tractor features a creeper gear system, allowing for enhanced torque and control at very low speeds, ideal for precise operations such as plowing or planting. With 12 forward and 3 reverse gears, it offers significant flexibility in different work scenarios, providing operators with the ability to adapt to varied field conditions. However, the complexity of the gear system may require more maintenance and operator training to fully optimize performance.

| Gears | 12 forward and 3 reverse |
MECHANICAL
The Ursus 3512 tractor features a 4x2 2WD chassis, offering simplicity and lower maintenance compared to 4WD models, but may struggle in off-field conditions or on steep terrains. Its power steering enhances maneuverability, while the mechanical wet disc brakes provide consistent braking performance, albeit with potentially higher maintenance compared to hydraulic systems. The optional cab and 8-speed/12-speed creeper transmission increase operator comfort and allow for precise speed control, ideal for tasks requiring fine adjustments such as plowing or planting.
