Key Features
Mulches vegetation up to 2 inches (5 cm) in diameter ideal for clearing grass, orchard prunings, brush, and small saplings with clean, consistent results.
Compatible with mini and compact track loaders requiring 13 To 28 GPM hydraulic flow, making it an efficient solution for landscape contractors, farmers, and municipalities.
Built from high-tensile S420 steel, the reinforced chassis withstands demanding terrain and heavy-duty use in vineyards, parks, pastures, and roadside maintenance.
Features a floating SAE universal skid steer interface that follows ground contours for even mulching and reduced scalping, ideal for uneven terrain and sloped ground.
Available in two working widths 61" (SMWA 155) and 69" (SMWA 175) to suit a variety of loader sizes and job requirements.
Fitted with a triple helical rotor and SMW flails, delivering smoother operation, reduced vibration, and a finer mulch consistency for cleaner finished surfaces.
Optional Y DUO knife rotor configuration allows users to adapt the mulcher to lighter vegetation or fine finishing tasks.
Heavy-duty belt transmission system (3 belts on 155, 4 on 175) ensures reliable power transfer from hydraulic motor to rotor, improving longevity and performance.
Features two rows of tempered counter cutters inside the housing for enhanced shredding of fibrous or woody material ideal for orchard floor clearing and maintenance.
Includes an adjustable rear hood with rubber flap to control mulching output and particle size, enhancing safety and jobsite customization.
Integrated adjustable support roller with reinforced bearings provides height control, ground support, and wear resistance over time.
Weighs only 980 lbs (445 kg) for SMWA 155 and 1,090 lbs (496 kg) for SMWA 175, making it suitable for smaller skid steers without compromising performance.
Pre-configured for VARIO-FLOW hydraulic motors and supports variable displacement motor options for tailored hydraulic compatibility.
Requires a 3-line hydraulic system (pressure, return, case drain) to maintain optimal performance and protect the drive motor under high load conditions.
Ideal for professionals performing green space maintenance, roadside vegetation clearing, agricultural mulching, and right-of-way management, combining durability, efficiency, and cutting-edge engineering.

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.
Just got my Buffalo Turbine! Love it. Took a little bit to get used to getting the right angle for the nozzle, but not a problem. Side note, works much better if the frame is level as much as possible.
Love it!

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.
When I think of ripping it outdoors something else comes to mind, but I digress. This spreader is awesome. Works like a champ. The hopper is big enough to do my 1 acre lot for my applications. Just load once and go. I would highly recommend this spreader. It saves a ton of time and is a quality product.
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!!
