Gear ratios in tractors are typically chosen to balance the need for slow speeds for tasks such as plowing and towing with the need for higher speeds for transportation. Modifying the gear ratio might result in reduced towing capacity, increased fuel consumption, or even damage to the tractor's drivetrain and engine.
If you require faster road speeds, it's better to consider the appropriate type of vehicle for your needs, such as a truck or pickup truck. Modifying a tractor's gear ratios should only be done by qualified professionals who understand the mechanical implications and safety concerns associated with such modifications.
