What is tractive?

Tractive is a word that is not commonly used in English. However, based on the context of your question, I can infer what you might be asking.

Tractive could potentially refer to something that is capable of being pulled or drawn, such as a rope or a chain. In this sense, the word might be used to describe an object that has a strong pulling force or a high degree of tractivity.

Alternatively, tractive could also refer to a quality or characteristic that allows something to be pulled or drawn, such as a surface that is smooth and slippery, making it easy to pull objects across it.

Without more context, it's difficult to provide a more specific definition of the word "tractive." If you have any additional information or examples, I would be happy to try to help further.
