A wheel loader’s bucket is typically its biggest revenue generator. But with many different buckets to choose from, how do you know which type of bucket is best suited for your application?

Before performing tasks like loading, carrying and stockpiling, evaluate the bucket weight, capacity and expected material density. Also, understand the four most common bucket designs: general purpose, light material, multi-purpose and rock buckets.

In addition, consider ground-engaging tools. By specifying the right bucket, you can better meet your daily production targets and help maintain machine performance.

Determine material density

When sizing a bucket to your wheel loader, evaluate the bucket weight and capacity first. Calculate the average density of the material to be moved and compare it to the tipping load and lifting capacity of the wheel loader.

Also, consider you may be working with multiple densities – perhaps sand one day, rock the next – so spec the bucket based on the heaviest material it will handle. For instance, sand that absorbs moisture will be heavier wet than dry. Clean, washed aggregate densities can also vary from base fill densities.

Wheel loader manufacturers design machines to handle a predetermined loading cycle profile and working payload. Pushing a machine beyond these limits can accelerate wear, affect machine durability and significantly lower your return on investment.

Match bucket to application

A wheel loader’s bucket matters more than you may think. In fact, a bucket properly matched to its material could decrease the number of passes needed to fill trucks.

The most common bucket design is a general-purpose bucket for maximum filling and material retention. This design works best in day-to-day material handling or when working with a range of material densities, such as general aggregate in construction and municipal applications; cleaning feedlots in agriculture; and sorting material in recycling applications.

If you are looking to move larger loads with smaller densities, a light material bucket may be an economical solution. Light material buckets offer higher capacities than general-purpose buckets, making them ideal for lifting snow, mulch or other similar materials.

Generally, light material buckets are available with a pin-on or hydraulic quick coupler mounting. Some are available with a bolt-on cutting edge for enhanced digging capabilities.

Multi-purpose buckets can improve digging and bucket filling. They can load, carry and dump granular materials; grab irregularly shaped objects; and doze, level or spread soil and fill. Many manufacturers offer multi-purpose buckets with reinforced mounting plates for longer service life and reduced maintenance.

For more abrasive applications, consider pairing a wheel loader with a spade-nose-style rock bucket. Typically, these are designed to move higher-density materials, such as those found in quarries and mine operations and for larger road work and site development projects. Many attachment manufacturers offer this style bucket as a pin-on-only option with standard weld-on teeth to improve its durability in tough applications.

To help make the best decision when selecting a wheel loader bucket, visit your local dealer. They have formulas available to calculate size, material density and volume, and compare it to the size of the bucket to provide the best solution for your application.

Spec buckets based on the heaviest materials you expect them to handle.

Cutting through material can be made easier with ground-engaging tools, such as rugged bucket teeth. Many manufacturers offer a vast number of interchangeable bolt-on teeth options for general purpose, light material and multi-purpose buckets. Weld-on teeth are typically offered on heavier-duty buckets, such as rock buckets, to reduce wear.

Replaceable cutting edges and extra guarding can be added to buckets to protect and to promote overall productivity.

Rapidly change buckets

To help get the most productivity from your wheel loader, consider investing in a quality attachment quick-change mechanism. This is optional on most manufacturers’ machines to easily change general-purpose, light material and multi-purpose buckets.

Many more efficiencies can be gained from being able to rapidly change buckets or other attachments with a hydraulic quick coupler from the comfort and security of a cab. Additionally, some coupler systems are designed to eliminate greasing, requiring less maintenance and fewer replacement parts.

There is more to selecting the best wheel loader bucket than meets the eye. Evaluate the bucket weight and capacity first, then select the bucket design that best matches your application.
