Amulet B.R.U.T Rigid Thumb Attachments | Model Nitro Series | Machine Size 3-50 Tons | For Excavators
DESCRIPTION
The Amulet B.R.U.T Nitro Series Rigid Thumb Collection delivers a complete range of heavy-duty mechanical excavator thumbs engineered for 3–50 ton machine classes. Designed for maximum versatility, each model in the BN and B Series lineup provides powerful material control for demolition, land clearing, scrap handling, and logging applications.
Built with high-strength alloy steel construction, these rigid thumbs feature multi-serrated tines, reinforced mounting geometry, and heat-treated pins to ensure long-lasting durability under extreme workloads. The non-hydraulic mechanical design eliminates complex systems while maintaining reliable gripping performance across all job conditions.
From compact 3–8 ton excavators (335–400 lb units) to ultra-heavy 40–50 ton class configurations, each model is optimized for its machine category with balanced strength, precise fitment, and low maintenance requirements. With multiple sizing options, contractors can match the exact thumb configuration needed for efficiency, safety, and productivity on demanding job sites.
Key Features
Full Excavator Size Coverage (3–50 Ton) Covers a complete range of machine classes from 3-ton compact excavators to 50-ton heavy-duty machines, ensuring compatibility across construction, demolition, and forestry fleets with consistent performance and strength.
BN & B Series Model Flexibility Includes multiple configurations such as BN-2, BN-3, BN-4, BN-5, BN-6, BN-7, and B-Series NT models, allowing precise matching of thumb strength and size to specific excavator requirements.
Heavy-Duty Alloy Steel Construction Each thumb is built using reinforced alloy steel structures, delivering exceptional resistance to bending, impact, and fatigue during high-intensity demolition and material handling operations.
Multi-Serrated High-Grip Tines The serrated tine design enhances grip strength for irregular materials like rock, logs, scrap metal, and debris, improving control and reducing load slippage during operation.
Heat-Treated Pin System Equipped with heat-treated steel pins for improved durability and wear resistance, ensuring long-term performance even under continuous heavy-load working environments.
Mechanical Non-Hydraulic Design A fully mechanical thumb system eliminates hydraulic dependency, reducing maintenance complexity while providing reliable and consistent operation in rugged job conditions.
Multi-Class Weight Optimization Each model is optimized within its class, ranging from 335 lb compact units to 1500 lb heavy-duty thumbs, ensuring proper balance and performance per excavator size.
Demolition & Land Clearing Ready Engineered specifically for demolition, land clearing, forestry, and scrap handling, making it a versatile attachment for multiple construction industry applications.
Compact to Heavy-Duty Length Scaling Designed with 30 in to 78+ in overall length range, ensuring proper reach and control depending on excavator size and application needs.
Low Maintenance Operation With no hydraulic components, the system offers reduced maintenance needs, fewer failure points, and lower long-term operating costs for contractors.

Overall rating: 4.6 / 5 from 94 reviews.
I've started using the mulcher I on several parcels of land 10 acres . I have grind down a couple of 14 inch stumps. Caution the mount bracket behind the mulcher motor exhaust gets extremely hot even with gloves on . But the unit so far seems to works very good it's well put together.
The Firminator G3 is s heavy duty quality machine. The discs worked extremely well and planting and culti-packing is very smooth and easy. Working with Dillon at Ripping It Outdoors was a very good experience and seamless transaction.
After spending way to much money for forest mulching services I discovered this wonderful machine. It's not a giant powerhouse forest mulcher, but it does everything a property owner needs to maintain a forested property. I wish I would have found it sooner.
The Firminator is well built and functions well. I am having some trouble while planting mixed size seeds. Next time out I’ll try setting it so only the smaller seeds drop out the open it up for the larger seeds.
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.
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.
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.
Great piece of equipment. Performs far better than I expected. One piece of advice - if property is significantly overgrown, consider the tractor attachment first to bring down the over growth and then switch to the UTV attachment to maintain property. No complaints worked perfectly.
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!
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!!
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.
This is my first experience with Ripping It Outdoors. Fortunately I got Dillion as a representative and everything from sales to shipping was spot on..
Thanks Dillion for your help!!
The only thing is when hooking up the actuator on my ATV. The wire is long going to the plug in. What has happened in the past about this. Is their video showing the usage of the control?
