Tractors are mostly associated to the farming industry by most people, but they do have many other uses than just farming.
For a commercial farmer, they could not exist if they did not have a tractor to maintain their fields. Commercial farming has all kinds of different tractors, bailers, pickers .. etc to help get their product to market as quickly as possible and then turn around and replant so that that they can continue the process.
A great way to buy a tractor and keep your cost low is at an auction. Many times companies just need to liquidate their inventory to make room for new equipment and you can pick up their liquidated inventory at a fraction of the cost of new.
