- This OSAT is a hand cultivator. It is used to clear land and to assist in gardening tasks. This is an appropriate tool because it assists in making a better garden that will produce more crops. According to Midwest Gardening  cultivating has many benefits. They state that cultivating allows easier penetration of air, nutrients and water into the sun and wind dried soil. Cultivating also remove weeds that steal water and nutrients from the plants. Less supplemental watering is also a benefit gained from cultivating. By using a plastic tool, there is the benefit of the tool never rusting and allows for easy cleaning.
