What does “slip” mean in the context of tractor operation?

In the context of tractor operation, "slip" refers to the situation where the tires lose traction with the ground, leading to a loss of control over the vehicle. This can occur in various conditions, such as wet or muddy surfaces where grip is compromised, or on steep inclines. When a tractor experiences slip, the driver may find it difficult to maintain direction or speed, which can lead to accidents or unintended movement. Understanding and recognizing slip allows operators to take corrective actions, such as adjusting speed, changing surface conditions, or using equipment designed to improve traction, ultimately ensuring safer operation of the tractor.
