Tractors are like horses. That's basically why they were invented.
In the not-so-distant past, horses were in charge of the job that tractors now handle. Kids would ride tiny toy horses all around their field. The idea of a toy machine was odd, because machines were so new nobody had even considered they they could be toys! Today, of course, we're surrounded by machines. Kids love to play at work and, after a long day of play work, pass out in front of the TV while yelling "I'M NOT TIRED!" just like a real farmer does each night.
