We usually shred four to six inches below ground (ground level). If deeper grinding is needed, it can be ordered, although the price of stump grinding may increase. However, the depth to which a stump can be ground is subject to some limitations. While tree stump milling experts generally grind stumps to 4-6 inches below ground level, stump grinders can go deeper.
Some can grind stumps up to 13-20 inches below the ground surface. And others, such as vertical stump grinders, can reach a depth of up to 62.5 below ground level. Some machines can grind stumps up to 18 inches on the ground. That said, the industry standard is to grind the stump until there is no longer a log.
In fact, this is how we do it at Jackson Tree Service. You might be wondering, well, how deep does a tree stump go? The answer is that it depends. Some trees have shallower trunks than others. The general rule is that a white oak trunk is deeper than that of a sycamore tree, and a sycamore trunk is deeper than an aspen.
Beyond that, your local arborist can estimate the depth of the trunk when it comes out to grind it. Standard regulations state that only a stump 200 to 300 mm can be ground below the level of the surrounding ground. This has as much to do with the size of the equipment and the blade of the shredder as it does with the stump itself. Larger stumps take longer and cost more as it takes more time and labor to grind the stump.
The blade is so large, so it is necessary to remove small pieces, for the safety of the operator and maintenance of the equipment. Most people choose to grind a stump after a tree is removed because it's an eyesore, because it's a tripping or safety hazard, or because they want to plant something else in that area. If you have removed a diseased or pest-riddled tree, grinding a stump can help ensure that disease or pests do not spread. Removing the stump also prevents the tree from growing back.
Considering the rental costs and other costs that are incidental to the operation of the chopper, it is sometimes advisable to opt for a professional woodland service, as it may be cheaper than trying to grind the stump on your own. There are some things that can prevent stump grinders from reducing their maximum depth, so we'll mention some of the most common. Professional arborists and tree removal companies also have insurance against accidental property damage from tree removal and stump grinding. This is the ideal grinding depth because it offers a perfect balance between grinding costs and efficiency.
When stumps are against retaining walls, fences or buildings, it is very difficult to get the machine close enough to completely crush it. And you can also decide to simply ask the tree service company that is shredding your stump to get rid of them. Stump grinders that are available for rent by homeowners will be smaller and less powerful than those used by professionals, and you are unlikely to find a range of stump grinder models to choose from. Therefore, it is more invasive than the alternative that only refers to the use of a grinding machine to chew the stump.
Stump grinders are a fantastic kit for removing ugly or unwanted tree stumps, but they can be dangerous in the wrong hands. You need a professional; someone who knows how far to dig and how to grind to get that stump out easily, and who saves you money and precious time in the process. .
