Stump grinders or stump cutters can be an asset to a tree service or landscape company. A good starting point for your purchase is to decide between a wheeled or tracked model. There are pros and cons to both models. The wheeled units are typically smaller and the operator manually controls the movement of the cutter. The smaller size affords the advantages of affordability and ease of transport. These are usually belt-driven machines while tracked units are hydraulically controlled. These offer higher horsepower and the ability to deal with large and tough stumps more quickly. It may come down to budget and the scope of the work your business performs on a daily basis.
The stump will also play a big role in purchasing a stump grinder. Several factors considering the stumps themselves should be taken into account: diameter of the stump, terrain around the stump, height of the stump and desired below ground depth of the finished stump. Quantity is also another factor. Will you be clearing a lot of stumps or just the occasional stump? Time is money and these considerations should all play into your decision.
