[AT] Small Farm Tractors vs Garden Tractors

[Robinson]

	Actually two types of HP were measured at Nebraska.
One is "belt or PTO" (usually listed first) and the
other is "drawbar". The drawbar HP is seldom mentioned
in tractor HP discussions or advertising. If it is it
is usually mentioned as being drawbar HP. If no
reference is made it is usually assumed to be Belt/PTO
HP.
