Skid-steer loaders are versatile machines that are easy to operate and ideal for confined spaces. Bucket teeth are indicative of the type of work the equipment can do. Different teeth options offer enhanced penetration and breaking capabilities. Bucket payload can be measured by volume or weight.

Skid-Steer Loaders Skid steer loaders are one of the most versatile machines available in the construction industry. This equipment, really simple to operate, can turn within their own footprint, just like a tank, so it is ideal in confined spaces or in areas where construction activity has been finalized. Skid steer loaders have wheels and they can offer increased traction, ideal in snow or mud, reduces soil compaction and their tread system prevents damage to finished areas.
Bucket Teeth Along with the bucket, the bucket teeth or tips are very indicative of the type of work that the equipment is set up to do. Teeth might be permanently part of the bucket, attached by bolts, welded or some other means. These teeth might actually have added tips. If teeth are temporarily connected, as their edges wear out they can be replaced easily. Like the bucket, teeth selection is greatly influenced by the density of the material to be excavated or moved.
The penetration of the bucket into the digging surface is easier using sharper, longer, and narrower teeth. Figure shows teeth or tip options that are offered on Caterpillar excavating equipment. Short teeth are used for regular penetrating and breaking apart material. Long teeth are used for chiseling into and breaking apart a packed surface. Heavy-duty long teeth are wider like a chisel and used for breaking apart a packed surface. Heavy-duty abrasion teeth cover more surface area and are used for fitting under a load or breaking apart a larger area. Penetration teeth are used for heavy duty penetrating and breaking apart dense material.
Bucket payload can be measured by volume or weight. Volume is typically stated as struck measure of loose volume meaning that the material excess is scraped off flush with the top of the bucket (excavator) or the bowl (scraper or dump truck) or heaped at a specific angle of repose meaning that the soil will support or cling together when piled and maintain this configuration.
