## Description

Better to Have It — Especially the Real One. Darwin’s Grip wasn’t added to a trimmer. It corrected one. Inclined by design and balanced on purpose, this is the original extension handle system that changed how straight-shaft trimmers feel in your hands. The bend isn’t cosmetic. It shifts leverage, improves stance, and restores control where it belongs — with the operator. Professionals feel it immediately. Homeowners notice it before the first pass is finished. Clearer sightlines. Steadier control. Less fighting the tool. When the geometry changes, the work changes. Built from durable metal with a secure mounting system, Darwin’s Grip is engineered to hold its ground through the grind you’ve mastered. No seasonal shortcuts. No decorative plastic. Just deliberate design. Compatible with most standard straight-shaft string trimmers. Installation is straightforward. The difference is not. 30-Day Money-Back Guarantee. 2-Year bumper-to-bumper warranty on authentic Darwin’s Grip products. If it carries the logo, we stand behind it.

Review: Makes heavy work, light - I shouldn't have waited so long to get this attachment. I think it reduces brush cutting effort by 50% by reducing fatigue from constantly balancing shaft distance (weight of the tool) from the cutting surface making each pass a more precision cut. It results in less passes to get a finished result. It won't cut the brush for you but certainly make the job easier. I also liked that the extension handle could be adjusted to many different positions. I'm sure another user wouldn't position the extension exactly like I have positioned mine, so having infinite adjustability is a big plus. If you have a gas power trimmer, you need this.
Review: Works well for taller people using string trimmers - OVERVIEW: I'm 6'1" tall, and I use a Stihl FS91R trimmer. Prior to purchasing the "Darwin's Grip" handle, I had moved the D-handle all the way up, right next to the strap holder (after I'd cut away and discarded the plastic hand grip thing that came with 91R). Still, I found myself bending over more than I wished. So I went in search of a solution, and I found the "Darwin's Grip." I do a fair bit of string trimming per week: 10+ hours every week on a hilly, rock-strewn property in West Virginia. SUMMARY: after about six hours of mowing with the Darwin's Grip, I find it is definitely what it advertises to be: a way to remain standing more upright as I use the trimmer. It is definitely a positive addition to my FS91R. I rate this a 5-star product. INSTALLATION: not that challenging. I heeded the advice to avoid over-tightening the hex bolts. I snugged them down, but I did not crank hard on the bolts. It wasn't necessary: snugged down is all that's needed to hold the thing in place. POSITIONING: as others have noted, this will take some fiddling with to get it right for your preferences. For example, the pictures showed the handle on top of the trimmer shaft, at the "12 o'clock" position relative to shaft as you hold the trimmer. I found it more comfortable on my left arm (I'm right handed: I trigger with right and use my left on the handle) to rotate the whole assembly to the left so the handle is at about the 10:30 or 11 o'clock position. Just that little bit helped quite a bit. Expect the initial install to be an approximation, with fine-tuning of position to follow. Also, some "muscle memory" my need to be re-learned to use the new handle naturally. For me that took about an hour. QUALITY/WEIGHT: the whole assembly is very light weight, and I don't notice any difference with my FS91R (14lb machine) with this installed. It seems fairly sturdy, but I would not jerk on the handle, nor push down on it hard. With just normal pressures to control the trimmer this should be just fine. As others have noted, the weak spot in this is the toothed-swivel that allows adjustment of the handle up/down from the trimmer shaft. Again, normal pressures and it'll be fine; aggressive jerking, or pushing down hard would be a problem. VALUE FOR MONEY: the item is $70+ with tax, and at first blush that seems high. But in my early testing of this I've discovered two things: (1) my back is no longer fatigued; and (2) because my back is no longer fatigued, I take fewer pauses, which means my mowing gets done more quickly. Preliminary estimates has the time savings in the 20% to 30% range. So, for me, the $70+ expenses is forgotten, and now I'm enjoying the benefits.

## Questions & Answers

**Q: Will this work to attach to shovels and / rakes?**
A: Most cyclic quadrilateral shafts are ok. (round)

The trimmer shaft on the SRM 410X Echo is too big. A little wallowing out on the vise is required. 13/16 socket with adhesive sand paper(80GRIT) and bingo, perfect fit.

Also, the Echo P225 residential stick edger's shaft is too small so you will need to built up the girth. Hockey/Baseball Bat tape recommended.(cloth tape) Avoid plastic type tapes (duct tape, electrical tape, etc.)

Instructional video coming soon on the website.
