FA Side Boom Mower | Model FASBM 4200 | Cutting Width 42" | 16-27 GPM | For Skid Steers
DESCRIPTION
Reach beyond the limits of conventional mowing equipment with the FA FASBM 4200 Side Boom Mower a revolutionary skid steer attachment engineered to access challenging terrain and hard-to-reach areas that standard mowers simply cannot touch. Designed for municipalities, highway departments, utility contractors, farm operators, and property maintenance professionals, this articulating boom mower delivers an impressive 115-degree range of motion that transforms your skid steer into a versatile, all-terrain vegetation management machine capable of mowing steep embankments, roadside ditches, under guardrails, along fence lines, and countless other difficult-access locations.
The FASBM 4200 redefines what's possible in vegetation control by combining a 42-inch professional cutting deck with an advanced articulating boom system that provides 90 degrees of vertical reach and negative 25 degrees below horizontal allowing you to mow upward on steep slopes, outward along ditches and waterways, downward into drainage areas, and everywhere standard mowing equipment fails. This exceptional range of motion eliminates the need for dangerous manual trimming, reduces labor costs, improves operator safety, and dramatically increases mowing productivity across diverse terrain.
Built with the same rugged quality that defines all FA attachments, this side boom mower features two AR400 hardened steel blades that maintain their cutting edge through tough vegetation and light brush, a robust 1/4-inch steel deck that resists impact damage from rocks and debris, and a precisely engineered hydraulic system optimized for 16-27 GPM flow rates ensuring smooth, reliable operation with compact and mid-size skid steer loaders ranging from 40 to 90 horsepower.
At just 800 pounds, the FASBM 4200 maintains an ideal balance between stability during extended-reach operations and compatibility with smaller skid steer models. The lightweight yet durable construction ensures your machine remains balanced even when the boom is fully extended, providing safe operation on slopes and uneven terrain where heavier attachments would compromise stability and control.
This side boom mower excels in applications where conventional mowing equipment proves ineffective or dangerous: highway and roadway maintenance teams use it to safely mow steep embankments and ditches from the roadway, utility companies maintain vegetation under power lines and along right-of-ways without climbing dangerous slopes, municipal crews trim parks and public spaces with challenging topography, agricultural operations maintain pond banks and irrigation ditches, and property management professionals handle estate grounds, golf courses, and commercial properties with varied terrain features.
The up to 4-inch cutting capacity handles tall grass, weeds, light brush, and overgrown vegetation with ease, making it equally effective for routine maintenance mowing and reclaiming neglected areas. The articulating boom design allows operators to remain in safe, level positions while the cutting deck reaches out and down to tackle slopes that would be hazardous or impossible to mow with traditional equipment or even walk-behind mowers.
Installation is simple and straightforward with the universal skid steer quick-attach mounting system, providing secure connection to all major loader brands including Bobcat, Caterpillar, Case, John Deere, Kubota, and others. Hydraulic quick-connect couplers make attachment and removal fast and effortless, so you can switch between mowing operations and other skid steer tasks without wasting valuable time.
For professionals who face vegetation management challenges beyond the reach of standard equipment whether maintaining miles of highway right-of-way, controlling growth along waterways, managing estate grounds with rolling terrain, or maintaining public spaces with steep slopes the FA FASBM 4200 Side Boom Mower delivers the reach, power, and versatility to complete jobs safely, efficiently, and professionally. Stop risking worker safety on dangerous slopes and start leveraging the mechanical advantage of articulating boom technology.

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.
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!!
