Description
The High-Volume Heavyweight
The Stinger Series 4 (MB4) is engineered for the largest Compact Track Loaders and Utility Tractors on the market. It takes the deep-bottom design of the MB3 and adds significant height (nearly 30 inches) and durability. Whether you are loading snow, mulch, or heavy dirt, the MB4 maximizes every cycle.
1/4" Shell Standard
While most buckets use lighter 3/16" steel, the MB4 is built with a 1/4" Grade 50 Steel Shell. This heavy-duty construction prevents bowing and warping under the extreme breakout forces of 90HP+ machines. Reinforced with a top tube, side braces, and the signature Rolled Radius Insert, it is built to handle 30 cubic feet of material without flinching.
