Tackles Big Jobs with Ease

The 17-inch cutting swath, bump feed head, and .080-inch-diameter line mean this trimmer can handle whatever you throw at it.

Twist and Go Fueling
Powered by an easy-to-use 16.4-ounce propane canister that snaps into place, the Eco Trimmer starts quickly--simply Twist 'n Go. Its patented propane-fueled technology eliminates the need for mixing gas and oil and requires no choking or priming to start. For further convenience, propane canisters are widely available, and a single canister provides two full hours of run time.


This clever trimmer also cuts out the need for the winterizing, carburetor gum-up, and choking commonly associated with gas-powered models. With an engine that starts faster and runs cleaner, maintaining your lawn won't be the hassle it once was.

Low Fuel and Maintenance Costs
The Propane-Powered Eco Trimmer boasts low fuel and maintenance costs. Standard 16.4-ounce propane canisters are economical and readily available at most hardware stores, sporting goods stores, drug stores, and other locations where lawn and garden products are sold. You'll cut down on expensive trips to the gas station and eliminate the risks associated with storing gasoline near or in your home. An added bonus, the steel propane canisters are 100% recyclable when empty.

To further cut costs, this durable trimmer is incredibly easy to maintain. It's backed by a three-year limited carburetor warranty and a two-year limited manufacturer's warranty.

and EPA Approved
Winner of the EPA Clean Air Excellence Award, the Eco Trimmer exceeds 2011 EPA emission standards meant to reduce lawn equipment pollutants. When compared side by side with gasoline, propane is clearly the smarter choice. Propane not only helps keep harmful pollutants out of the air, but it is less expensive than gasoline, so it also helps keep your money in your pocket. What's more, 85% of propane used in the United States is produced domestically, which means propane-powered tools can help eliminate dependence on foreign oil and can help cut down on the waste associated with fuel spills.

In addition, propane contains no evaporative emissions and zero ozone-depleting hydrocarbons. It is a nontoxic substance that won't pollute ground water or soil, and it includes 97% fewer particulates and 96% fewer carcinogens than gasoline. A cleaner and greener alternative to traditional fuel, propane power is a great choice for your garden.

3.0 out of 5 stars Father's Day present July 7, 2009

By Roger P. Miles

I received the detachable, curve shaft model as a Father's day present. I've used it twice so far. It was easy to assemble and started after a few pulls. The manual said it takes a few minutes for the engine to warm up. At first, I wasn't impressed with it's power. I had the throttle fully engaged and thought there's no way the optional brush cutting attachment would work, but after a few minutes the rpms really ramped up. I had to barely touch the throttle to get good power.

I found the unit heavy, very unbalanced and awkward to use. I'm right handed and was using my right hand on the throttle. I had to pull up with my right arm to get the trimmer head near the ground. I'm 6'4" and perhaps the curve shaft wasn't the best choice for me. I tried moving the handle, but when I positioned the handle where it was comfortable for me I had to bend my knees to get the trimmer head down to the ground.

The second time I used it it again started right away, but when I was almost done the engine stopped. I thought I was out of propane and went to change the canister. I found the canister covered with oil. I switched the canister anyway and heard a hissing sound coming from the engine (the propane was leaking) and oil was dripping out. I called customer support and they told me I put too much oil in it. I rejected this idea because the manual and an extra flier warned about putting to much oil in. The support rep assured me I put too much oil in and said the full marker on the dipstick is not right. It's about 4/5 the way up the stick and the rep told me the full mark is really about half way up. The hissing sound was coming from the carburetor diaphragm and the rep told me how to reset it (this is not in the manual). I removed some oil and reset the diaphragm and everything appears to be ok.

While I had the rep on the phone, I inquired about returning the curved model and getting the straight shaft model. The rep said they only accept returns when there is a catastrophic engine failure and suggested since I had the detachable model I could buy the detachable straight shaft for $179. Since the curved unit cost $199 this seemed unreasonable to me.

Since I'm stuck with it, I tried to make some improvements. I added some weight to the trimmer end so I wouldn't have to hold up the engine end (only 1 or 2 pounds). This made a big difference. I also want to add something to the handle to make it longer so I don't have to bend my knees.

I rate the Lehr a 3 out of 5 mostly because of the no return policy and the weight. If you're over 6' I would definitely buy the straight shaft model. If you have a lot a trimming to do, the weight will be an issue, but adding a little weight to the trimmer head end to counter the weight of the engine works for me.

1.0 out of 5 stars Not so great April 3, 2010

By Mikenwa

I purchased one last summer and have had several problems since. After about 5 minutes of running, it stalled and was very hard to restart. Every few minutes it would stall even if it was running fast, and it would never idle properly. I noticed that it was leaking oil from the recoil starter, so I called the support number where my best experience was getting a very helpful tech. We determined that it had a bad crank seal and they exchanged a new engine to correct my problem. By the time I was up and running, the weather had tuned cold, so I only ran it long enough to test it. Now that spring is here, I got it out and had trouble starting it again. I had to prime the carb to get gas into it, but finally got it going. The first time I needed to let out more string, I bumped the release as per the instructions and it wouldn't feed more string. I have now had almost every part of this thing apart to correct problems. Here is what I have learned both from the techs and from my own experience.

You must remove the gas line from the propane tank after each use or the carb will be damaged. The unit should not be hung on the wall, as it must be stored level to keep oil from leaking. You can only run the motor for short times with the engine not level or it will not be lubricated properly, like when using it for edging because the motor has an oil pump and pickup tube which must be submerged in the crankcase oil to provide oil pressure. The dipstick is not accurate and you will have problems if you add oil up to the full mark and some were shipped with more oil than is needed, so you can't use the entire bottle. The tank strap will be stretched and damaged if care is not taken to get the tank in the right position before clamping it. You sometimes have to prime the carb to get it to start by pushing a small wire or paper clip through a little hole in the bottom of the carb until you hear gas hissing. Most of these problems are not discussed in the manual but make ownership less desirable than I had hoped.

I find it to be heavy and poorly balanced for anything but brief use. I also question the better for the enviroment pitch when it uses disposable canisters that are good for a couple of hours of run time. The only positive features are that it does run quieter than the 2-cycle types and does not smoke.

I would not have bought it if I had known what I do now, plus it cost more than most gasoline versions do.

Now after the second season I find it easier to pull grass and weeds by hand than to fight with getting this unit started. I have lowered my rating to 1 star.

3.0 out of 5 stars Heavy & awkward June 6, 2009

By J. McGowan

Amazon Verified Purchase

I bought the Curved Detachable Shaft model. The unit was easy to assemble and the engine started on the 2nd try. It appears well built and has plenty of power. The problem I have is that to get the head level with the ground for even cutting I had to hold the engine high in the air with my elbow bent outward which, was very awkward. Since it is fairly heavy and held in an unnatural position my arm tired quickly. I am 5'11" and weigh 185 and am in fairly good shape.

A great idea, well constructed but, could be improved to be more ergonomically friendly. I reluctantly returned the trimmer and hope that Lehr will come out with a better design.
