By the end of this article, you will have a good sense of how the machine works and why it is a fantastic investment for your garden.

How Does the Tertill Weeding Robot Work?

The Tertill weeding robot gets rid of weeds in a garden by trimming them down and preventing them from growing. It has specially designed wheels with which it stirs the top layer of soil, destroying pre-emergent weeds.

The 3-inch treaded, four-wheel-drive wheels loosen the soil and keep it well tilled, which explains the ’till’ in “Tertill.”

The robot’s trimmer trims down small weeds that escape the wheels. The machine also has a spinning whacker mechanism that uses a nylon string to cut down taller weeds.

It uses sensors to differentiate between normal plants and tall weeds.

The sensors apply capacitive sensing similar to the one used in smartphones and tablets to detect objects.

They generate a small electric field with which they measure and detect changes in the field caused by objects such as living plants, wire fences, and moist landscaping timbers.

These sensors prevent the machine from whacking plants that are taller than 4 inches. A Tertill weeding robot considers anything that is tall enough to touch its front sensors a good plant and turns away.

Plants that are less than 4 inches tall, such as seedlings, are protected from whacking by plant guards that come with the machine. Place the guards around your small plants, and the robot will turn away when it gets too close.

A Tertill weeding robot operates in intervals of two to five minutes that cumulate to a total of one to two hours per day. Also, they are built to cover up to 200 square feet of garden area. The machine produces chiming sounds a few seconds before it starts working.

Once your garden is ready for the robot, press the go button twice and watch as the Tertill weeding robot destroys the weeds therein.
