After felling a tree, there are a few reasons you should consider removing the remaining stump: it is an eyesore, it makes mowing and lawn care difficult, and tree stumps are notorious for sprouting shoots in an attempt to regrow the tree. The decomposing stump is also prone to fungus and pests, which have the potential to infest nearby healthy plants.
Follow these steps for safe and efficient stump removal
Prepare the Stump
Before digging into the stump, you will need to prepare the stump and surrounding area. Clear a wide area around the stump, particularly of anything you wouldn’t want covered in mulch. You don’t want to lose your chainsaw under a pile of chips! Remove any large rocks from the base of the stump as these will cause unnecessary wear and damage to the cutter teeth. Optionally, you may use a chainsaw to trim the stump closer to the ground, though this step is not necessary providing your stump falls under the maximum operating height of your selected machine.
Follow Safety Procedures
Read and understand all operator and safety instructions before operating your equipment. Call 811 to locate any underground utility lines before operating. Stump grinders are loud, powerful machines and the cutting wheel rotates quickly and throws debris clear of the cutting head. Consider the proximity of any buildings, windows, and vehicles to avoid any damage from flying debris. Ensure all bystanders are wearing eye and ear protection and are well away from the machine to avoid injury. Anyone operating the machine, or assisting the operator, should wear adequate PPE (personal protective equipment).
Read the manual and understand the operating instructions for your selected stump grinder. Whether you are operating the cutter head via handlebars or controls, the procedure for approaching and grinding the stump will be identical for each type of machine.
Position the machine so that the cutter wheel is over the edge of the stump. Move the engine to full throttle and engage the cutter wheel. Slowly swing the cutter head in a sweeping motion across the edge of the stump. Lower the cutter wheel and repeat the swing in the opposite direction. To avoid bogging the engine or stalling the cutter wheel, listen to the engine and pay attention to the cutter wheel speed, adjust cutting depth and swing speed accordingly. Continue until the stump is cut at least four inches below ground level.
Cleanup and Fill
Rake and remove all chips from the area. You may be surprised at the amount of mulch you’ve created with this project. The good news is you don’t have to throw it all away. Consider using those chips in your garden.
If you have removed your stump from a landscaped area, the following steps illustrate how to restore the area.
Remove as many remaining tree roots and as much debris as possible. This will prevent fungal disease as the remaining pieces may continue to decay underground. Rake the remaining soil and gently pack the hole with fill dirt, ideally a topsoil similar to the surrounding area. Lightly water the soil to settle the dirt. Fill again if needed to level the area. You are now ready to spread grass seed or plant ornamental flowers in the fresh soil.
Remember that tree roots will grow around and through all obstacles in their path. Always Call 811 and identify any utilities before you dig. Happy Grinding!
