The word tractor, derived from the "traction engine," indicates the importance early tractor designers place on developing traction. That importance has not diminished. Engine power can be converted to drawbar power only if the drive wheels develop traction. Factors such as tire selection, hitching, ballasting, and implement selection determine whether engine power is transferred to the drawbar efficiently or inefficiently. By learning the traction terminology and principles presented in this chapter, you will gain useful insight about how to attain high pull and tractive efficiency from a tractor. Techniques for estimating a tractor's potential pulling ability using data given in a Nebraska or OECD Tractor Test will be examined.(Download PDF) (Export to EndNotes)
