Key Features
Heavy-Duty AR400 Steel Tines Construction ensures unmatched durability and wear resistance in harsh job site conditions. The 1-inch thick tines and reinforced ladder-frame design provide exceptional gripping strength for handling heavy, irregular materials with confidence.
Optimized Hydraulic Cylinder Performance System features a double-sealed welded cylinder with spherical bushings, reducing side-load stress and increasing longevity. This design ensures consistent operation, even under demanding excavation and demolition workloads.
Wide 18" x 50" Thumb Coverage Area delivers superior material handling efficiency by increasing contact and grip range. Ideal for large debris, logs, and rocks, improving productivity and reducing repositioning time on site.
115-Degree Maximum Extension Angle Capability allows extended reach and flexibility for grabbing and positioning materials. This enhanced articulation improves operational control and efficiency across a wide range of excavation tasks.
Compact Stowed Design for Better Digging Clearance keeps the thumb tucked close to the stick when not in use. This minimizes interference, allowing uninterrupted trenching, grading, and digging performance.
Top-Mounted Hydraulic Ports for Hose Protection keeps hydraulic lines safely routed away from debris and pinch points. This reduces wear, damage risk, and costly downtime due to hose failures.
Hydraulic Cushion System for Cylinder Protection absorbs shock at the end of the stroke, preventing internal damage. This feature significantly extends cylinder life and ensures smoother retraction cycles.
Reinforced Gusseted Frame Structure Design enhances overall rigidity and strength, allowing the thumb to withstand heavy loads and repeated stress without compromising structural integrity.
Greaseable Pins for Easy Maintenance Access simplify routine servicing and extend component lifespan. This reduces maintenance downtime and keeps your equipment operating at peak efficiency.
Hardened Main Pin and Bushings Durability improves wear resistance and ensures long-term reliability under continuous heavy-duty use. Ideal for contractors requiring dependable performance over time.
Fast Cycling with Large Hydraulic Port Size enables quicker thumb movement and improved workflow efficiency. This helps operators complete tasks faster and increase overall job site productivity.
Compatibility with 12–19.5 Ton Excavators makes it a versatile solution for mid-to-large machines, providing a perfect balance of strength and operational efficiency for demanding applications.
Weld-On Mounting for Secure Attachment Fit ensures a stable and customized installation tailored to your excavator. This enhances safety, performance, and overall attachment reliability.
Backplate Engineered for Structural Stability provides a solid mounting foundation that distributes stress evenly, reducing wear and improving attachment longevity during heavy operations.

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?
