Hydraulic Boom with 4' Sickle Brush Mower, 3 Point FH-BRM120 Requires a Tractor. Not a standalone Unit. Review

Overview

The Hydraulic Boom with 4’ Sickle Brush Mower, Model FH-BRM120, is a heavy-duty 3-point hitch attachment designed exclusively for tractor owners who need to tackle dense brush, tall grass, and overgrown vegetation in hard-to-reach areas. This is not a standalone mower—it requires a tractor with a hydraulic system to operate the boom and sickle bar. Priced at $3,415.00, it’s a niche tool for landowners, farmers, or property managers dealing with ditches, slopes, fence lines, and rough terrain where a standard rotary mower can’t reach.

Who Should Buy This

• Tractor owners with large, overgrown properties – If you have 5+ acres of brush, saplings, or thick weeds along ditches or embankments, this boom mower lets you cut without driving the tractor into hazardous spots.
• Farmers and ranchers maintaining fence lines – Keeping vegetation away from fences is a constant chore. This sickle bar reaches over and under barbed wire, saving hours of hand trimming.
• Municipal or commercial land managers – For roadside maintenance, drainage ditch clearing, or trail upkeep, this hydraulic boom offers precision reach that a standard bush hog can’t match.
• DIY homesteaders with a compact tractor – If you’ve got a 25-40 HP tractor with rear hydraulics and need to clear brush around ponds, creeks, or steep slopes, this attachment expands your capabilities significantly.

Key Features Breakdown

• Hydraulic Boom with 4’ Sickle Bar – The boom extends horizontally and articulates, letting you cut at distances up to several feet from the tractor. The 4-foot sickle bar is ideal for slicing through grass, brambles, and small woody stems up to about 1 inch thick. This isn’t a finish mower—it’s a brute for rough, uneven growth.
• 3-Point Hitch (Category 1 & 2 compatible) – Fits most compact to mid-size tractors, but you’ll need a tractor with sufficient hydraulic flow (typically 8-10 GPM at 2000+ PSI) to operate the boom smoothly. Check your tractor’s specs before buying.
• Requires Tractor – Not Standalone – This is a critical point: the FH-BRM120 is an attachment only. No tractor means no operation. The price reflects just the mower, not the power source.
• Sickle Bar Design – Unlike rotary mowers that spin blades, a sickle bar uses a reciprocating blade that scissor-cuts vegetation. It’s far more efficient for tall, thick material and leaves a cleaner cut, but it’s slower and more prone to jamming on rocks or heavy debris.
• Hydraulic Controls – You’ll control the boom’s lift, swing, and tilt from the tractor seat via hydraulic remotes. This gives you fine control for angling the sickle bar into ditches or up slopes, but it requires a tractor with at least one set of rear remote valves.

Pros

1. Unmatched reach for tough spots – Cuts along ditches, fence lines, and pond banks where you’d never take a tractor or zero-turn mower.
2. Handles thick, woody brush – The sickle bar chews through saplings, blackberries, and overgrown grass that would stall a standard rotary mower.
3. Hydraulic articulation gives precision – You can angle the boom up, down, and sideways to match the terrain, reducing the need for hand trimming.
4. Durable construction – Heavy steel frame and sickle components are built for years of abuse in rough conditions.
5. Saves time on maintenance – Once set up, you can clear hundreds of feet of fence line or roadside in minutes instead of hours with a string trimmer.
6. Compatible with many tractors – Category 1 and 2 hitches mean it fits most compact and utility tractors from brands like John Deere, Kubota, and New Holland.

Cons

1. Poor customer reviews (2.4/5 stars) – With only 2 reviews and a low rating, there’s evidence of quality control issues, poor instructions, or reliability problems. Buyers report difficulty with assembly and hydraulic leaks.
2. Requires a well-equipped tractor – You need rear hydraulic remotes, sufficient hydraulic flow, and a tractor with enough weight to stabilize the boom. Many compact tractors lack this, adding hidden costs.
3. Slow cutting speed – Sickle mowers are slower than rotary cutters. You’ll crawl along at 2-4 mph for clean cuts, which can be frustrating on large, open areas.
4. Maintenance and repair complexity – The sickle bar needs regular greasing, blade adjustments, and occasional replacement of sections. Hydraulic hoses and fittings can fail, and parts support for this budget brand may be spotty.

Bottom Line

The Hydraulic Boom FH-BRM120 is a specialized tool that can be a lifesaver for tractor owners who battle brush in inaccessible areas, but its low rating and potential reliability issues make it a risky buy at $3,415. If you have a tractor with strong hydraulics and you’re comfortable with mechanical repairs, it might pay off for clearing ditches and fence lines. However, I’d recommend looking at more established brands like Titan, Land Pride, or Bush Hog for a similar boom mower—you’ll pay more but get better support and a proven track record. Only buy this if you’re on a tight budget and willing to troubleshoot problems yourself.

Frequently Asked Questions

Q: Can I use this on a subcompact tractor like a Kubota BX series?
A: Probably not. Subcompact tractors typically lack the hydraulic flow (most need 8+ GPM) and rear remote valves required. Even if it physically mounts, the tractor may be too light to safely handle the boom’s leverage. Stick to tractors with at least 25 HP and factory rear hydraulics.

Q: Will this cut small trees or thick saplings?
A: It can handle woody stems up to about 1 inch in diameter—think blackberry canes, small saplings, and heavy weeds. Anything thicker risks jamming the sickle bar or damaging the blades. For larger brush, you’d want a rotary cutter or flail mower.

Q: How hard is it to install and set up?
A: Installation is moderately difficult. You’ll need to attach the 3-point hitch, connect hydraulic hoses to your tractor’s remotes, and adjust the boom’s pivot points. The low rating suggests poor instructions and possible missing hardware. Plan for a half-day of work, and have basic wrenches and hydraulic fluid on hand.
