Putting the stump grinder in place 

The first step is to put it close to the stump that needs to be cut down. The operator carefully moves the machine into place, making sure it’s stable and lined up right.

Engagement of Grinder

Now that the grinder is in place, the grinding wheel needs to be engaged. When the user turns on the engine, the wheel starts to spin very quickly. When the wheel’s teeth or blades touch the stump’s surface, they start to chew away at the wood.

Gradual Grinding of Stump

The grinding wheel starts to remove layers of wood as it runs along the stump. The person controlling the grinder moves it back and forth, turning the stump into wood chips and sawdust over time. The process is slow but steady, and you need to be patient and careful.

Depth Control

The user changes the depth of the grinding wheel based on the size of the stump and the result they want. This makes it possible to carefully cut down the stump so that it is below ground level.

Turns Off the Grinder

The user turns off the grinder and checks the area once the stump has been ground down to the desired depth. After getting rid of any last bits of wood chips or trash, the surface is clean and level.
