You must purchase the 4x4 Harvester ($45) and/or the 4x4 Plow ($45). Both of these may be bought with farm cash.
A tractor will plow, the harvester will...harvest. They both have different functions.
You don't have to be a level you have to have 10 neighbors on farm town.
All you have to do to hire plowers on farm town is to go to the marketplace and click on an avatar. Next just click hire to plow and if they agree to work for you then they will go to your farm. For cool farm town cheats check out http://farmtownheaven.com
Someone has to hire you to plow for them, and someone has to hire you as a harvester.

Tractors plow the soil so you don't need to manually plow it one by one. It requires gas but is very effective and fast. There's also the Seeder and Harvester who basically does almost the same thing.
