How do tractors help people?

Answer 1

A tractor is essentially a mobile power source, so where every where power is required you'll find a tractor.

In acient times field work was done entirely by hand, even though the invention of agriculture had freed up some people to start building civilisations it still took a whole village of labourers using basic hand tools such as Hoes and Scythes to feed that village.

The next step was the use of animals and heavier duty tools such as a plow. This had the effect of allowing one man to do the work that it took twenty to do in the past. This had the dual effect of freeing up people to do other jobs that were previously less important than growing food and also allowing more ground to be worked.

The original steam "Traction Engines" were just as big a step as using animals even if they were a large stationary engine on wheels. This new machine could, with help from a winch, pull a plow. It could also do jobs that animals couldn't really do well such as powering saws or mills. Best of all it would stay where you left it, it didn't tireat the end of the day and didn't require two paddocks of feed for every one that it worked.

A single modern tractor can work more ground than an acient villager would have seen in their entire life and works an area the size they did in a few seconds. The powerful diesel engines they run combined with their hydraulic systems allow them to lift very large loads. One single tractor can feed hundreds of people and that's how they help. One man with one tractor can feed many many others allowing for people to all sorts of useless jobs like Planner, Knowledge Consultant or anything in Finance without needing to worry where their next meal is coming from.
