Designed to move at slow speeds, but deliver a tractive
effort is the tractor. It generally describes a farm
vehicle that deals with construction or agricultural tasks.
The 2012 Tractors calendars show some of the many types that
are used on a farm. The history of the vehicle dates
back to the beginning of the 19th century. Most of
those simplistic models are not seen in the pages of these
Tractors 2012 calendars, but they are the basis for how they
look today. Tractors can also pull or push a variety
of different machinery behind them in order to plow, plant,
and till. There are even compact tractors that can
work in small spaces. |
