Product Description

Werk-Brau Skeleton Rock Bucket | Width 48"–72" | 20–40+ Tons | For Excavator

DESCRIPTION

The Werk-Brau Skeleton Rock Bucket is a heavy-duty excavator attachment engineered for demanding quarry, rock, riprap, drainage, and road-base applications. Its specialized skeleton design allows operators to dig, separate, and size material simultaneously, retaining larger rocks while allowing unwanted fines and smaller debris to pass through. Built with high-strength, abrasion-resistant steel, reinforced wear straps, and tapered side plates, this bucket is designed for demanding jobsites where durability and efficient material handling are essential. Optimized tine spacing helps maintain the desired material size while improving separation performance. By separating material directly at the excavation point, the Skeleton Rock Bucket can help reduce secondary screening, rehandling, and unnecessary haul weight. Available in multiple widths, it is suitable for compatible 20–40+ ton excavators, making it a practical solution for heavy-duty material separation and rock processing.

Key Features

  • Heavy-Duty Rock Separation Designed for demanding quarry, excavation, and rock-processing applications, the Skeleton Rock Bucket efficiently separates large rocks and debris from finer material during normal excavator operation, helping operators improve material handling directly at the jobsite.
  • Optimized Tine Spacing Precision-designed tine spacing helps retain target-sized rock while allowing unwanted fines and smaller particles to pass through, providing effective material separation without requiring every load to undergo a separate screening process.
  • Dig and Size Simultaneously The bucket allows operators to dig, separate, and size material in one operation, making it useful for riprap, drainage rock, road-base preparation, quarry work, and other applications requiring controlled material separation.
  • High-Strength Steel Construction Built using high-strength, abrasion-resistant steel in critical wear areas, this excavator bucket is designed to withstand demanding rock-handling conditions and repeated contact with abrasive materials on challenging jobsites.
  • Reinforced Wear Straps Reinforced wear straps provide additional protection in high-contact areas, helping improve attachment durability during heavy excavation, rock separation, quarrying, and other intensive material-handling operations.
  • Tapered Side Plates Tapered side plates are engineered to support efficient material release during dumping while helping reduce unnecessary wear, improving bucket handling and discharge performance during repetitive excavation cycles.
  • Reduced Secondary Screening Separate material at the source to potentially reduce additional screening passes, rehandling, and material movement, helping streamline workflows where coarse rock must be separated from smaller debris.
  • Clean Rock Loads The Skeleton Rock Bucket helps produce cleaner rock loads by allowing unwanted fines to fall through the tine structure, potentially reducing unnecessary haul weight and improving the quality of material delivered to the dump point.
  • Quarry-Ready Design Purpose-built for quarry and heavy rock applications, this attachment provides a practical solution for excavators working with large rocks, coarse debris, drainage materials, riprap, and road-base material.
  • Multiple Width Configurations Available in documented 48", 54", 60", 66", and 72" widths, allowing buyers to select a compatible bucket configuration according to excavator size, application requirements, and desired material-handling capacity.
  • Heavy Excavator Compatibility Designed for compatible 20–40+ ton excavators, with documented 40MT configurations intended for approximately 82,500–105,000 lb excavators, subject to the selected bucket configuration and machine specifications.
  • Efficient Material Handling The open skeleton structure supports material screening during excavation, allowing smaller particles to fall through while retaining larger material, helping reduce unnecessary handling and improve overall jobsite efficiency.
  • Improved Dumping Efficiency Tapered side plates and open tine construction support smoother material release during dumping, helping operators efficiently discharge separated rock and debris during repetitive excavation and loading cycles.
  • Built for Abrasive Conditions Abrasion-resistant construction and reinforced wear areas make this attachment suitable for challenging environments where rock, stone, quarry material, and coarse debris can subject conventional buckets to significant wear.
  • Versatile Rock Applications Suitable for riprap, drainage rock, road base, quarry material, and coarse debris separation, providing excavator operators with a versatile attachment for material processing and heavy-duty excavation tasks.

Customer photo review of Ferntree Mini Excavator Forestry Mulcher | Model FF-L Series | 22"-30" Cutting Width | Machine Size 2.5- 6 Ton | For Mini Excavator

easy buying process and great communication. Mulcher works great, easily clears overgrown brush and even mulched a 5" thick mulberry tree fairly easily. running it off of my old 331 bobcat with no problem powering the drum at all. Only small issue which isn't a big deal is that the supplied hoses are about 16" too short to operate a full range of motion.

Ferntree Mini Excavator Forestry Mulcher | Model FF-L Series | 22"-30" Cutting Width | Machine Size 2.5- 6 Ton | For Mini Excavator

Over all built well. I like it is all cast iron and metal and not plastic. Had to modify fertilizer disc mount to fit correctly, nothing major, a little grinding. I modified the center link hitch point to accommodate my John Deere quick hitch. Have yet to plant with it but I’m sure it will work perfect. Love the grease fittings everywhere. Reminds me of the old farm equipment I grew up on, and still use periodically.

Cole 12 MX Multiflex Planter | Model B46-664A / 0120103 | Width 13" | Size: One Row | 3PT Hitch Planter Attachment | Horsepower 25–45 HP | For Tractor

My firminator RT was delivered in good condition in ND. I will be using it next week. I have a 45 HP John Deere tractor that is supposed to lift 2000 lb but really struggles to lift this 6 foot firminator RT. I will just have to use in as a two pass operation for now. I do wish there was a better operating manual for this unit. Maybe that is something you can work on. I will give you an update once I start using it in a few days.

Put this on Kubota 900 with winch hookup. This thing is a beast (within reason). I named it ‘Homie”, cause Homie don’t play. It will take care of stuff up to about 2” in diameter. You still have to remember that this is NOT like the ones on a bobcat or larger machinery. It does have its limits. But all in all I am very satisfied with it. Now on to the good part! The staff at Ripping It are outstanding! Especially Kayla in the office. She has gone above and beyond on making sure everything went right, from ordering to questions about installation. This young lady would be of great value at ANY company ! Her knowledge and personality are like over the top. This is my first experience with Ripping It Outdoors and I can only say positive things about them. With all that being said, I do fill out reviews on things I buy, AND I give a honest review. If it’s bad then you will know it. But if it’s good, well I tell the truth ! Again Kayla, from the bottom of my heart, a great big THANK YOU for all your help and just talking to you. I feel like we’ve know each other for years!

Forax Gas Powered Mulcher | Model GP40 | 40" Cutting Width | 14HP Kohler Motor | For UTV Side by Sides and Tractors

TENT is easy to put up , material is tuff as told....only complaint is that i wish the bottom had about 3 to 4 inches overlap towards the inside so i could install a 2 x4 or something to help hold the tent down in high winds we have here in virginia thanks

Hi, my name is Ken. I’ve had a great experience with Ripping It Outdoors. I purchased a Forax Hp40 Mulcher for my mini excavator. Kayla Patterson is who I dealt with from the beginning until I received it at my house. She has been wonderful to work with and looking forward to working with her with any other orders I purchase. Kayla answered any questions I had and kept me updated throughout the whole process, can’t say it enough just a wonderful person to work with!!

Forax Ultralight Mulcher | Model HP40 | Cutting Width 40" | Carrier 2-4-Ton | For Excavators

These are great feeders if you don’t have any feral hogs but if the hogs tear off the wiring harness from the timer to the feeder motor, you’re disabled. Then, if you ask for help from Outback, they refer you to the dealer but really you’re on your own for parts and repairs. I have three Outback feeders that work as designed. They’re 13 years old and have always served well but this feeder misses the mark by a very high margin. I’d NEVER buy this product again. Feeders need to be dependable and this unit is not.
