The Stinger Attachments Series 4 material bucket is a step up from our series 3 in capacity. The Series 4 comes standard with a ¼” Grade 50 Shell. These buckets are engineered to hold up to the largest machines on the market day after day. Available in 5 different sizes from 60 to 84" inches in width. This material bucket attachment comes standard with a universal skid steer mount plate. We can also custom fit other mounting options or leave plain so you have the option to custom fit your own. Our top channel brace and bottom radius support add the strength needed to handle the biggest machines. The bottom-radius support also adds better clean out. Our standard back degree angle is 68 degrees. We have found this to be a very good fit for most machines in the roll-back and dump positions. The bucket is available with two cutting edge options. Option 1 (Weld on Edge), we weld on a large 3/4x8 Edge to the bucket shell. Option 2 (Bolt on Edge), we weld a 1/2x6" edge with holes to bucket shell, then bolt on a 3/4x6 edge to the bottom.
