Tractor Material Bucket Attachment – Maximum Capacity for Heavy Material Handling

When you're tackling the biggest material handling jobs on your property or job site, you need a bucket that won't quit. The Tractor Material Bucket – Series 4 (MB4) from Stinger Attachments is built specifically for operators who demand maximum capacity, serious durability, and all-day reliability. This is the largest-capacity material bucket in the Stinger lineup, and it's engineered from the ground up to handle heavy loads, aggressive use, and the kind of punishment that comes with moving dirt, gravel, mulch, and debris day in and day out.

Forge Claw is proud to distribute this heavy-duty attachment nationwide, offering free shipping to contractors, landscapers, farm owners, and land managers who need equipment they can count on. The MB4 isn't just another bucket. It's a purpose-built workhorse designed to match the power of larger tractors and loaders without compromising visibility, control, or structural integrity.

What sets the Series 4 apart is its construction. Stinger builds this bucket with a quarter-inch premium grade 50 steel shell, which delivers exceptional strength without adding unnecessary weight. Grade 50 steel offers a higher yield strength than standard mild steel, meaning it resists bending and deformation even under serious stress. Whether you're scooping compacted fill, loading wet gravel, or moving bulk landscape materials, the MB4 holds its shape and keeps working.

The bucket measures 40 inches deep, which does two important things. First, it increases struck and heaped capacity so you can move more material per cycle. That means fewer passes, less fuel burned, and jobs that get done faster. Second, that extra depth improves your line of sight to the cutting edge, so you can see exactly where you're digging and avoid obstacles, buried utilities, or uneven terrain. Visibility matters when you're working around structures, along fence lines, or in tight spaces.

Stinger gives you flexibility with cutting edge options. The MB4 is available with either a weld-on or bolt-on cutting edge, depending on how you prefer to maintain your equipment. Bolt-on edges make replacement fast and easy without needing to break out the welder. Weld-on edges offer a low-profile design and a clean look. Either way, you're getting a bucket that's ready to dig into hard-packed soil, gravel, and aggregate without hesitation.

The sides of this bucket are built to last. Stinger uses quarter-inch side plates reinforced with half-inch thick side braces for added rigidity and impact resistance. These braces prevent the sides from flexing or bowing out when you're carrying heavy, uneven loads. It's a small detail that makes a big difference in long-term durability, especially if you're regularly loading rock, debris, or other abrasive materials.

Across the bottom of the bucket, you'll find four or five wear bars depending on width. Each bar measures 4 inches wide by half an inch thick, and they're positioned to take the brunt of ground contact and abrasion. These bars protect the bucket floor and extend the life of the attachment significantly. When they eventually wear down, they're replaceable, which means your investment keeps paying off year after year.

At the top of the bucket, Stinger includes a reinforcement tube that spans the full width. This tube adds torsional strength and prevents the bucket from twisting under load. It also improves visibility when you're dumping or grading because it creates a consistent reference line. The result is better control and more confidence when you're operating in challenging conditions or tight quarters.

Inside the bucket, there's a quarter-inch rolled insert that strengthens the back wall and improves cleanout. Material flows more smoothly when you dump, and sticky or wet loads release easier. That rolled edge also protects the bucket from impact damage when you're loading from piles or scooping against hard surfaces.

Stinger includes a step on the bucket for easier access to your tractor or loader. It's a thoughtful touch that makes daily operation safer and more convenient, especially when you're climbing in and out multiple times throughout the day.

The MB4 is available in five widths: 60, 66, 72, 78, and 84 inches. That range gives you the flexibility to match your tractor's lifting capacity, your loader arms, and the type of work you do most often. Struck capacities range from 17.2 to 24.2 cubic feet, with heaped capacities reaching up to 30.3 cubic feet in the 84-inch model. These are serious numbers that translate directly into fewer trips, faster cycle times, and more productivity per hour.

Weights range from 690 pounds for the 60-inch model up to 950 pounds for the 84-inch version. These figures are based on the bolt-on cutting edge configuration. The bucket is heavy enough to provide good ground penetration and stability, but not so heavy that it overloads smaller tractors. Stinger engineered the MB4 to balance capacity, strength, and usability across a wide range of machines.

The Tractor Material Bucket – Series 4 saves time on every job by allowing you to move more material per cycle. With struck capacities ranging up to 24.2 cubic feet and heaped capacities reaching 30.3 cubic feet, you'll complete loading, grading, and site prep tasks in fewer passes. That means less time spent on repetitive scooping and more time moving on to the next project. Whether you're spreading gravel for a driveway, loading compost for a landscaping job, or moving dirt for a drainage project, the MB4 keeps you moving.

Durability is built into every aspect of this bucket, which translates directly into lower operating costs and better return on investment. The grade 50 steel shell resists bending and cracking, the replaceable wear bars protect high-wear areas, and the reinforced sides prevent damage from heavy or uneven loads. You won't be dealing with constant repairs, premature wear, or unexpected downtime. The MB4 is designed to work season after season without losing performance or structural integrity.

Productivity improvements come from more than just capacity. The 40-inch depth gives you better visibility, so you can work faster and more accurately without second-guessing your bucket position. The rolled insert improves material flow, so you spend less time shaking out sticky loads or scraping debris. The reinforcement tube keeps the bucket stable and true, even when you're pushing hard into piles or dumping at awkward angles. All of these details add up to smoother, faster, more confident operation.

On the job site, reliability matters as much as performance. The MB4 is built to handle the kind of abuse that comes with commercial work, from rocky soil and compacted fill to wet clay and mixed debris. The heavy-duty construction means you can push harder, load fuller, and work longer without worrying about equipment failure. That peace of mind lets you focus on the work instead of babysitting your attachments.

Cost savings extend beyond the initial purchase. Because the wear bars, cutting edge, and critical stress points are replaceable, you can maintain this bucket for years without major expense. The rugged construction reduces the frequency of repairs, and the thoughtful design minimizes wear on your tractor's hydraulics and loader arms. Over the life of the attachment, those savings add up significantly compared to cheaper, poorly built alternatives.

Real-world job site value comes from equipment that adapts to your needs. Whether you're a contractor working on multiple sites, a landscaper managing seasonal projects, or a farm owner handling year-round material movement, the MB4 delivers the capacity, strength, and versatility you need. It's equally at home loading mulch, moving gravel, cleaning up construction debris, or grading driveways. One attachment handles a wide range of tasks, which means fewer attachments to buy, store, and maintain.

The Tractor Material Bucket – Series 4 is ideal for contractors, landscapers, farm owners, ranch managers, and land clearing professionals who operate larger tractors and need maximum material handling capacity. It's particularly well-suited for high-volume work like site preparation, large-scale grading, bulk material loading, and seasonal cleanup. If you're moving significant amounts of dirt, gravel, mulch, or aggregate on a regular basis, this bucket will quickly become your most-used attachment.

This bucket is designed to work with tractors and wheel loaders that have the lifting capacity to handle both the bucket weight and full material loads. Make sure to match the bucket width to your machine's hydraulic capacity and loader arm strength. Stinger builds this attachment to fit most standard quick attach mounting systems, but it's always smart to confirm compatibility with your specific machine before ordering. Lead times may vary depending on size and configuration, so contact Forge Claw for current availability if you're working on a tight timeline.

For best results, operate the MB4 with smooth, controlled movements. Let the cutting edge do the work when digging into piles, and avoid jerky motions that can stress the loader arms or hydraulic system. When dumping, tilt the bucket fully to take advantage of the rolled insert and let gravity help with cleanout. Periodically inspect the wear bars, cutting edge, and side braces for signs of excessive wear or damage, and replace components as needed to maintain peak performance.

Routine maintenance is straightforward. Keep the bucket clean to prevent buildup that can add weight and reduce capacity. Check bolts and fasteners regularly, especially after the first few hours of use, and re-torque as needed. Inspect welds and structural components for cracks or stress, particularly if you're working in rocky or highly abrasive conditions. With basic care and attention, the MB4 will deliver years of dependable service.
