Do any of you use a walk behind 4-stroke string trimmer?

My helper broke his ankle and I suddenly have to do the weed whacking on my 3 acres of rough terrain orchard and nursery. I was hoping to get a small walk behind sickle-bar mower, but apparently they aren’t being manufactures any more except as part of an expensive Italian machine. Troybilt used to make them for a reasonable price.

For a little under $500 I can purchase a string trimmer on wheels, but I don’t like the look of the spool- or the lack of one. Looks like you have to replace the string a lot.

You will have to replace the string a fair bit.

Make a PVC capped pipe extra string holder that you zip tie to the handle to hold the extras. Buy a spool and cut your own as well - dont start cutting without at least 15 extra strings.

I prefer a regular string trimmer (or brush cutter) with a harness personally. If you use it when it’s wet (no fire risk) you could use a grass blade.

If you have any hills they suck. Also hard to get close to things without touching them or accidently chopping them down. They do work well if you put a blade on them and use them for light brush work.

I have one, but I’ve only used it a few times in the last 10 years. It’s not very maneuverable and a pain in the ass using on my uneven terrain.

I have one. Kind of a pain to replace the plastic string strips all the time. I prefer the stihl 2 cycle with cutting blade attachment. I got a chainsaw blade attachment off amazon I want to try. weed eater string is not for large weed / brush removal.

Thanks folks. I used to have an Italian walk behind tiller with a sickle bar I could use by turning it around and putting it in front. It cut much better than string.

When my guy got hurt I let the weeds go and it rained and then we had drought which apparently all makes the crab grass and other weeds especially tough. I have the heaviest Stihl trimmer which is a relative beast.

I need a better strap that supports it over both shoulders. Every 10 minutes I have to shift the thing to spread the stress. At my current 5’10" X150 pounds I’m not really built for heavy equipment although I still punch higher than my weight class…

Can anyone suggest a good strap?

I use the Stihl Kombi KM131R at the orchard for weed control around the trees. It’s obnoxiously heavy and I wouldn’t be able to use it without the full harness. I use the Stihl Double Standard Harness, but the Universal Double Standard Harness looks a bit nicer (for 2x the price). I’m only 5’8" and were I any shorter the harness and length of the trimmer shaft wouldn’t work together, the head of the string head would be at an angle. You should be fine at your height.

You want one of these: https://www.cubcadet.com/en_US/prior-year-models/st-100/25A-26KF710.html

Have had ours for maybe 7years now. Starts within a couple pulls every time and will cut down brush with ease. Not, “string”, rather heavy pieces maybe 20"? long. Super simple and quick to change. Last a Very long time, even hacking down brush/sapplings.
Got ours from a place called Clarks Service in Regina, in case that helps.

Stihl make a couple of different styles of straps. I didn’t even know that their new machines come with a strap until I purchased one of their FS 91 earlier this year. I am running the absolute heaviest cutting line I’ve ever seen, the spool of which I originally purchased for the 4 stroke walk-behind string trimmer that I have. I cannot say enough good things about using this 0.155 inch diameter line in my handheld gas powered string trimmer. The simple bandoleer harness I have is easy to slip over my head to put it on and take it off (I leave it clipped to the machine at all times). If you were to purchase the full harness then you would likely want to unclip.


I really liked using the 4 stroke walk-behind string trimmer. I actually quit using our rotary blade lawnmower and used the DR Power machine for general lawn maintenance for quite a while. With the correct trimmer string in it I thought that it was a great tool.

I ordered a full harness knockoff of the Stihl design for $30 from Amazon. We shall see.

That Club Cadet string trimmer is no longer manufactured and much in demand apparently. The only one on Ebay right now is $460 plus God knows what shipping.

Never used a walk behind but have done a lot of brushing with a harness mounted trimmer. The key for me is having the bicycle handlebars and a lightweight trimmer. Much less torque on your shoulders and neck when logging long hours.

Something like the FS311 is very powerful but also super heavy. I wouldn’t go heavier than the FS91 unless you are doing light forestry work with it. I have a FS56 currently and it’s slightly underpowered but totally adequate ( including cutting brush like ninebark).

Lastly, the 3-lobe blades are best for general use. They are easy to sharpen with an angle grinder and still cut well when dull. They’ll cut up to about the diameter of your thumb. The chainsaw or circular saw types are fun and useful if you’re only cutting trees, but if you hit dirt twice they will be useless until sharpened again. Not worth the time for general brush and grass.

I would second the note about heavy trimmer line. I don’t know why they even sell the thin stuff. I’m running the heaviest line I can finagle into the spool mechanism.

My neighbor has one of these. based on his experience, I’d probably pass.

he got the wrong tool for the job he has to do. He has a couple of small fields he lets an area farmer cut for grass hay, and he wants to trim the edges of the field against fieldstone walls. it’s a lot of in and out and back forth and rock eats trimmer line.

I’ll second the note about getting the heaviest line you can put in it. handheld, four cycle, it don’t matter. My personal preference is for trimmer line with edges, tri-wing or whatever. I have no hard evidence to support this preference, just my observations based on my experience.

I got something called a gorilla grip last winter, as the bending with using a weed eater really gets to me. A friend of mine with a lawn business also got one. We think we’re old dogs and new tricks may be too much for us. Either that or we need to fiddle with the adjustment and tweak it to our use. fyi.

Got a question for you: What do you call rough terrain?

I use a zero turn mower like most people use a walk behind billy goat brush mower. only thing that defeats me is wet ground. or gravity. I use gator blades, with the rakes on the back side, and I kid you not, if I can drive over the stuff, I can cut it.

I have an exmark and a simplicity courier. the courier is small and light, and that is the strength and the weakness. slopes are harder with the simplicity because the drive pumps are smaller, and going downhill, gravity can overcome the controls. i have a theory that r4 tires would change how this machine handles (for the better), but I don’t have the motivation to do this.

the exmark…the only thing that stops me is mud.

alan…you’re not too far from me (danbury, ct area). i have a bcs sickle bar. if you can use it, i’ll make an offer you might have a hard time saying no to.

I have a sickle bar for the other Italian walk behind, known as Mainline in the U.S. (Goldoni in Italy where it used to be made). I will let you have that one along with the small tractor itself for free- but good luck finding parts. It was still running when I parked it on my land 15 years ago and covered it with a tarp. I couldn’t really use it on my land because there are too many obstacles including tightly spaced nursery trees and all sizes of rocks and boulders as is common in Putnam County, NY. The land is also pretty steep. Luckily this spot also held onto a fair amount of soil that supported full sized native forest trees before I gradually removed them to make room for orchard and nursery. My fruit trees grow exceptionally well for a relatively light soil.

I used to use its roto-hoe to break up soil before doing installations of trees from my nursery. Now I just use a shovel unless it’s a big job- then I have someone else use a back-hoe. .

I got tired of wheeling it to where it was needed:

Which of those two machines is the mower? :wink:

I ended up buying a more expensive string head and a harness for my Stihl beast. The harness is weird and difficult to figure out, not coming with an owner’s manual, but I figured it out well enough to make it a lot more comfortable than the shoulder strap I was using.

I’m amazed how much better the string head works than the cheap type I have been using over the years. The Stihl version is very expensive but the one I put on my machine was about $16 on Amazon- twice the cost of the cheapy models.
