Description

HLA Attachments MB78HDBO500 78-Inch Heavy Duty Standard Front-End Loader Bucket combines durable construction, practical capacity, and a universal skid-steer-style quick-attach interface for demanding material-handling work. This MB78HD bucket is built with 1/4-inch bucket material, 1/4-inch end plates, a reinforced top lip, and a substantial 3/4 x 6-inch beveled cutting edge. Its reinforced round back supports strength while promoting easy filling and cleanout, making the bucket well suited to routine loading and material movement. The 78-inch inside width provides an approximately 80-inch outside width, while the BO500 mounting configuration allows use with compatible universal skid-steer-style quick-attach carriers.

Heavy-Duty Bucket Construction

The MB78HDBO500 is designed around a strong, reinforced bucket structure. Both the main bucket material and the end plates are 1/4 inch thick. Reinforcement across the top lip, round back, and end plates helps the bucket withstand demanding work while maintaining a practical shape for loading and unloading.

A reinforced round back allows material to flow into the bucket more easily and supports cleaner discharge during unloading. Tapered, self-cleaning end plates further reduce material buildup. These design details help improve filling and cleanout without adding unnecessary complexity.

Capacity and Working Dimensions

This model has a 78-inch inside width and an approximately 80-inch calculated outside width. Its 30-inch depth and 25-inch height provide an 18.3-cubic-foot struck capacity and a 23.1-cubic-foot SAE heaped capacity. The bucket weighs approximately 670 lb.

The flat top of the bucket also serves as a convenient level indicator. This gives the operator a clear visual reference for bucket angle when approaching, collecting, carrying, or discharging material.

Cutting Edge and Accessory Options

A 3/4 x 6-inch beveled cutting edge provides a durable working edge for loading applications. The bucket is also drilled to accept a standard bolt-on cutting edge, allowing the working edge to be equipped with one of the available optional edge configurations. Optional knock-on ripper teeth are available for applications requiring a more aggressive material-engagement setup.
