Key Features
Precision Grading Performance Designed for accurate finish grading and material control across construction, agricultural, landscaping, and land-maintenance applications. Machine-control compatibility helps operators achieve consistent grades while reducing unnecessary material movement and rework.
108-Inch Working Width The wide 108" grading blade covers substantial ground with every pass, improving productivity on large jobsites while maintaining the maneuverability needed for tighter work areas and detailed grading applications.
8-Way Blade Adjustment Multiple blade adjustment functions provide exceptional versatility for grading, contouring, crowning, ditching, side-shifting, and windrowing. Operators can quickly adapt blade positioning to changing terrain and material-handling requirements.
8–30+ GPM Hydraulic Flow Engineered for skid steer and compact track loader hydraulic systems with 8–30+ GPM flow capability. The hydraulic system supports responsive attachment operation and precise blade control for demanding grading applications.
Laser & GPS Ready Supports advanced laser, GPS, 2D, and 3D machine-control systems for automated grading and precision elevation control. Compatible guidance solutions can help operators maintain accurate grades and reduce material overages.
3D Grading Capability Built for advanced 3D contour grading, allowing contractors to tackle complex surfaces, slopes, and elevation changes with greater consistency. Ideal for professional earthwork where precision and repeatability are critical.
Stable Grading Platform A stable attachment design helps maintain consistent blade engagement across the working surface. This supports smoother finish grading, improved operator control, and dependable results across demanding jobsite conditions.
Oscillating Front Axle The oscillating front axle helps stabilize operation over uneven terrain by allowing the grader to better follow ground conditions. This improves blade contact and contributes to smoother, more controlled grading performance.
Windrow Left or Right Flexible material management lets operators windrow material left or right, making it easier to move soil, aggregate, and other materials efficiently while adapting to site layout and project requirements.
Side-Shift Functionality Side-shift capability expands the blade's working versatility, helping operators position the cutting edge where material needs to be moved. It is useful for grading near edges, slopes, roads, and other challenging areas.
Reversible Cutting Edge The reversible cutting edge provides extended usability and helps maximize component life. Reversible design allows the cutting edge to be repositioned when needed, supporting dependable performance during repeated grading operations.
Foam-Filled Tires Foam-filled tires provide a stable, durable foundation for precision grading. They eliminate concerns associated with pneumatic tire pressure changes and help maintain consistent attachment performance during demanding work.
Proportional Hydraulic Valve The integrated proportional hydraulic valve provides controlled hydraulic operation for smooth attachment adjustments. Responsive hydraulic control helps operators make precise blade movements during fine grading and material positioning.
Loader Joystick Integration Machine integration harnesses allow manual grading through existing loader joystick controls, simplifying operation and reducing the need for separate manual controls. Designed for efficient integration with compatible skid steers and track loaders.
Built for Tough Jobsites A powder-coated finish, flat-face hydraulic couplers, hoses and fittings, convex material-visibility mirror, and heavy-duty construction make the GB108 well suited for demanding professional grading environments.

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.
Seems to be in order delivery wasn't able to use lift gate but tractor was able to take pallet off the truck bed. No damage to machine after visual check. won't know how it runs until rain stops.
Staff at RippingitOutdoors was very quick to call and double check the type of backet needed for the unit to ensure the online order matched( to fit my skid steer quick attachment on my l2501 Kubota). Explained the teeth & belt could be ordered through them directly over the phone when/if needed as well as selling other types of custom made brackets for Utv's ect. All around Great customer service and would purchase from again.
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?
