Product Description

Sundown Offset Flail Mower | Models FRF125 To FRF165 | Cutting Width 47" To 63" | 20 To 50 HP | For Tractor


DESCRIPTION

Built for demanding roadside, ditch, and embankment work, the Sundown Offset Flail Mower delivers unmatched versatility for compact and utility tractors. Designed for rear and lateral offset operation, this heavy-duty mower tilts 65° downward and 90° upward for vertical transport, making it ideal for highway shoulders, slopes, drainage ditches, and fence lines.

Powered by a Series 4 PTO shaft and equipped with a hammer-style rotor, it easily cuts thick grass and small branches while leaving a clean, professional finish. The hydraulic side shift and tilt system allows precise control from the tractor seat, while side skids and an adjustable rear roller maintain consistent cutting height on uneven terrain. Built exclusively with hammers for durability, the Sundown Offset Flail Mower is the perfect solution for operators who demand precision, safety, and productivity in challenging mowing environments.

Key Features

  • Hydraulic side shift system delivers smooth lateral movement and angle control, allowing precise mowing along ditches, embankments, and tight roadside areas
  • Dual-direction tilt capability allows 65-degree downward cutting and 90-degree vertical positioning for safe transport and extreme slope access
  • Heavy-duty hammer rotor efficiently shreds grass, weeds, and small branches while reducing debris throw for safer roadside operation
  • Series 4 PTO driveline ensures reliable power transfer from tractors running 20 to 50 horsepower under continuous working conditions
  • Rear roller height adjustment maintains consistent cutting height while improving ground following on uneven or sloped terrain
  • Side skid protection system shields mower housing from ground impact and extends machine life in rough roadside environments
  • Offset mowing design improves visibility and reach when cutting under guardrails, fences, and hard-to-access areas
  • Category I three-point hitch allows fast attachment to compact and utility tractors without additional adapters
  • Vertical transport position reduces overall width and improves safety during road travel and equipment storage
  • Hammer-only configuration provides superior durability and performance when mulching thicker vegetation and brush
  • Balanced rotor assembly minimizes vibration, improving operator comfort and extending bearing and driveline life
  • Compact machine footprint makes the mower easy to maneuver while still covering wide cutting paths efficiently
  • Industrial steel housing withstands continuous commercial use in highway, municipal, and property maintenance jobs
  • Requires dual hydraulic remotes for independent control of tilt and side shift functions directly from the tractor
  • Multi-model width options allow operators to choose the ideal cutting width for tractor size and job requirements

Customer photo review of Ferntree Mini Excavator Forestry Mulcher | Model FF-L Series | 22"-30" Cutting Width | Machine Size 2.5- 6 Ton | For Mini Excavator

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.

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!!

Forax Ultralight Mulcher | Model HP40 | Cutting Width 40" | Carrier 2-4-Ton | For Excavators

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.
