TRANSMISSIONS OVERVIEW
The Renault 981 tractor features a 12-speed partially synchronized transmission, providing a balance between ease of shifting and power management, alongside a 16-speed creeper option for optimal low-speed control during tasks like tilling or precision plowing. The partially synchronized design enhances operational efficiency, reducing the risk of gear grinding, while the creeper gear offers exceptional torque for heavy-duty applications. An advantage arises in scenarios requiring fine maneuvering, which can significantly improve work quality in confined spaces or uneven terrain.
