The Stinger Attachments HDB Hydraulic Dump Bucket is built for wheel loaders that need more dump height when loading high-sided trucks, hoppers, bins, and containers. Hydraulic cylinders tip the bucket forward at the loader’s full lift height, giving you additional dumping reach without relying on the rollback and dump angle of a traditional bucket alone.
Available in 6′ through 10′ sizes with capacities from 1.1 to 2.0 cubic yards, the HDB combines a reinforced underframe, replaceable cutting edge, and greaseable pivot points for demanding material-handling work. Multiple mounting options allow the bucket to be configured for compatible wheel loaders and coupler systems.
What does a hydraulic dump bucket do?
The HDB uses hydraulic cylinders to tip the bucket forward independently of the wheel loader’s normal bucket-dump motion. This increases the effective dump height and makes it easier to clear high-sided trucks, hoppers, bins, and containers.
Is this version designed specifically for wheel loaders?
Yes. This listing is for the wheel loader version of Stinger’s Hydraulic Dump Bucket. Mounting and machine compatibility should be verified for the specific wheel loader before ordering.
What sizes are available?
The HDB is available in 6′, 7′, 8′, 9′, and 10′ sizes, with capacities ranging from 1.1 to 2.0 cubic yards.
How much does each size hold?
The 6′ bucket holds approximately 1.1 cubic yards, the 7′ holds 1.3 cubic yards, the 8′ holds 1.5 cubic yards, the 9′ holds 1.7 cubic yards, and the 10′ holds 2.0 cubic yards.
Does the Hydraulic Dump Bucket require auxiliary hydraulics?
Yes. The hydraulic cylinders that operate the dump function require an auxiliary hydraulic connection on the wheel loader.
What mount options are available?
The HDB is available with either a Universal Quick Attach mount or a Construction mount for coupler plates up to 1″ thick. Always verify your wheel loader’s coupler style before ordering.
What is the advantage over a standard wheel loader bucket?
A standard bucket relies on the loader linkage for its final dumping position. The HDB adds another hydraulic dumping motion at the bucket itself, allowing material to discharge higher when the loader is already at full lift.
What types of material can the HDB handle?
The bucket can be used for common bulk materials such as soil, gravel, feed, compost, mulch, manure, and similar materials, provided the load remains within the wheel loader’s operating limits.
Is the cutting edge replaceable?
Yes. The HDB uses a 3/4″ × 8″ bolt-on reversible cutting edge. It can be reversed to use the opposite wear surface and replaced when worn.
Are the pivot points serviceable?
Yes. The dump mechanism uses 1″ greaseable and replaceable pivot pins for easier maintenance over the life of the attachment.
How do I choose the correct size?
Choose the bucket based on your wheel loader’s lifting capacity, hydraulic capabilities, coupler, machine width, material density, and the volume you need to move. Larger buckets provide more capacity but also add attachment and payload weight.
Note: Compatibility depends on your wheel loader’s coupler style, auxiliary hydraulics, lifting capacity, machine width, ballast, and the HDB size selected. Stinger offers multiple wheel loader mounting configurations, including common Global and ISO-style agricultural and construction mounts. Always verify the exact machine, coupler, and bucket size before ordering. Not every HDB size is appropriate for every loader listed below.

Stinger Attachments provides a two-year manufacturer warranty against defects in material and workmanship from the date of delivery to the original purchaser.
Reach higher without moving to a larger loader.
The hydraulic dump action adds another dumping motion at full lift, helping the bucket clear taller truck beds, hoppers, and containers.
Move more material per cycle.
Five bucket sizes and capacities up to 2.0 cubic yards let you match the attachment to your wheel loader and the volume of material you regularly handle.
Build around your wheel loader.
Multiple mounting options allow the HDB to be configured for compatible wheel loader couplers instead of forcing the machine into a one-size-fits-all attachment setup.
Keep wear components serviceable.
Replaceable pivot pins, wear skids, and a reversible bolt-on cutting edge make common wear areas easier to maintain over the life of the bucket.
At ECHO Eqpt, we actually use and support the equipment we sell. You’re not getting generic answers, you are talking to people who understand how this equipment works in the field. That means faster answers, better recommendations, and no wasted time trying to figure things out on your own.
We’re easy to work with. If something breaks, tell us what actually happened and be honest with us (a good sense of humor doesn’t hurt either). We’re often known to help out even outside of standard warranty terms. And if it’s on us, we’ll own it and make it right. No excuses, no finger pointing - just real support when it matters.
