HLA Attachments - 78" Regular Duty High Volume Front-End Loader Bucket - High Volume Loader Bucket [LA-MBHV78BO500]

The HLA Attachments MBHV78BO500 78-inch Regular-Duty High-Volume Front-End Loader Bucket combines generous material capacity with a reinforced, self-cleaning bucket profile. Configured with HLA’s BO500 quick-attach mounting package, this high-volume material bucket has a 78-inch inside width, a 29.5-cubic-foot struck capacity, and a 35.7-cubic-foot SAE heaped capacity. Its reinforced round back and tapered end plates are designed to promote easy filling, efficient cleanout, and reduced material buildup, while the flat top provides a convenient visual level indicator during loader operation.

Regular-Duty High-Volume Design

The MBHV78 is constructed from 3/16-inch bucket material with 1/4-inch end plates. A reinforced top lip, reinforced round back, and reinforced end plates add strength throughout the bucket structure. The round-back profile supports smooth filling and cleanout, making the bucket well suited to high-volume material-handling applications.

At the working edge, the bucket uses a heavy 3/4 x 4-inch bevelled cutting edge. It is also factory-drilled to accept a standard bolt-on cutting edge, allowing the wear surface to be equipped with one of HLA’s compatible optional cutting-edge accessories when required.

Designed for Filling and Cleanout

Tapered, self-cleaning end plates help reduce material accumulation inside the bucket. Together with the reinforced round back, this shape encourages material to enter and leave the bucket cleanly. The flat upper surface also acts as a level indicator, giving the operator a straightforward visual reference for bucket position.

The bucket measures 34 inches deep and 30 inches high. HLA lists the inside width at 78 inches and calculates outside width by adding 2 inches, resulting in an approximately 80-inch overall outside width. The base bucket has an approximate weight of 635 lb; the weight of the BO500 mounting package is not published.
