Skid Steer Buckets: Know Your Material Weights

Skid steers are heavy pieces of machinery built for efficiency and labor-saving in industries like construction, landscaping, farming and mining. They have lift arms which are used to attach a wide variety of skid steer attachments, including skid steer buckets. As a skid steer operator, it is important to know three different capacities before operating with a skid steer bucket attachment. These capacities include your tipping capacity, and the two types of bucket capacities, heap capacity and struck capacity.

Tipping capacity is the most important of the 3 capacities that you should be aware of. Tipping capacity refers to the amount of weight your skid steer can physically handle before it tips. This is extremely important to know not just for operating with skid steer buckets, but any skid steer attachment. Heaped capacity refers to the amount of material inside the bucket plus the amount of material stacked on top (heaped). Struck capacity refers to the amount of material on the inside physical dimensions of the bucket only. Both heaped and struck capacity are measured in cubic feet.

Knowing both heaped and struck capacity will ultimately help you determine the weight of the material in your bucket (materials are measured in lbs / cubic feet), so that you know how much you can carry without reaching your tipping capacity and putting yourself and those around you in harms way.

If you have any questions on the type of bucket you need to get the job done, or on the 3 capacities that were discussed, contact our experts at!
