I did a lot of research and decided on this trimmer because of the reviews and the engine size and the price. Set up is literally just fold up the handle and tighten 2 thumb screws then add the oil. I was very happy that the motor oil came with it. Installed the strings and it was ready to go. Mine has a fuel primer bulb and it started on 3rd pull. It cuts really well even in the heavy stuff. Woody stalks up to about 1/2” are no problem. It won’t cut the thicker stuff at the base but you can tilt the trimmer up and cut the branches down. My place was really overgrown because of the summer heat and and I have a sore back. This trimmer cuts the work by 75% of my big double handle Stihl hand held weed whacker. It starts easily even when hot and is very easy push with no back ache when you’re done. I was surprised at how easily it pushes. The big wheels Really make a difference. You will change string often in the heavy stuff and especially around chain link fences but that’s true with any trimmer and at least it’s pretty easy to do. I sort of wish it had an auto feed line dispenser is about the only criticism I have for it. Honestly though, I battle the darn auto feeds on my other trimmers and I was interested in this to see how much trouble it would be to change strings. It is very quick and easy. Be sure to buy extra line because it only comes with a few starter pieces. I bought a big roll and cut my own sections. I think I’m gonna try some steel cable instead of the plastic stuff. I have 3 good quality Stihl trimmers of different sizes and this wIll replace them as my first go to tool. Wish I had bought this years ago instead of my big Stihl trimmer except I can run a metal blade with my hand held to knock down the really bad stuff. This machine reduces how much I have to cut with hand held tremendously so it’s a good combo for me. I have 70 acres in north east Texas and this is a real time saver and back saver for me. Excellent bang for the buck.

Still new, so take that into consideration. Might add after using it for a few months or a year. For now - could not be better. Cuts through raspberry canes with ease. Tall grass & weeds - 3 feet tall and thick stems/trunks. Not trees, but thistle, nettle & heavy Prairie grasses. Changing the plastic cutting pieces is easy. They do not wear quickly. Engine has not bogged & starts easily - we'll see if that keeps up with age. With the large wheels it is easy to maneuver & handles well.

So disappointed! Machine was great but a part broke right away. Months later it is still on back order. Do not buy as it breaks easily and parts cannot be replaced. We have missed the entire season of use.

I was hesitant to buy a string mower but this is amazing. It was super easy right out of the box. It was very easy to adjust the handle, put on the guard. add oil and gas. It started right up and I went through three foot tall weeds with no problem. I am super surprised and very happy.

Writing this review 5 hours after receiving the equipment. Delivery was fantastic--got it less than 24 hours after ordering--and the box was in great shape. Unboxed it, went and bought a small (1.25 gal) gas can (which I filled with zero-ethanol 87 unleaded), a quart of Mobil 10W 30 pool and some extended funnels, then came home and set up the cutter (attach 1 piece with 4 provided screws, then position the handle where you want it and tighten the adjustment knobs). Fill with oil (btw, it actually comes with a small bottle of oil, but I didn't realize that until later), fill with gas, prime it, then pull the recoil starter cable. It's that easy. Onto the performance aspect of the tool... I have close to a half acre that I've "let go." All manner of southern vegetation occupies this area now, so it is a fairly challenging task for a string mower right out of the gate. Add the uneven and unpredictable terrain, and it also becomes a challenge for the operator as well. I started my trimming with the challenging terrain, but manageable weed portion of my yard first... and I had a smile plastered on my face the whole time. This thing chewed through the weeds like they were nothing, as if to say, "Is that all you've got?" Well, no... that wasn't all I had, and the rest of my weed/tall grass mowing really pushed this machine to it's limits. While I'm still impressed with this string brush cutter, it was no match for the ridiculously dense, tall grass that I had to tackle. But I set my expectations accordingly when ordering this (it was a decision between dropping close to $500 on a string mower or $3,500 on a bladed brush cutter like DR Power or Billy Goat... I chose this in the end with no illusions about what I would be asking of it), and I'm not disappointed in the least. I did have to fill the gas tank up 3 times to handle the portion that I did (it's still not completely done yet), but for a tank that holds less than a quarter of a gallon and the work that I had it do, it was no surprise and not a big deal. I had to change the string once during use, but really, it should have been twice, as at the end, when I decided to call it quits, my cutting swath was probably down to 9 or 10". I'm going to level up my string game and try the A ANLEOLIFE 1-Pound ZT3 Pro Heavy Duty Diamond .155-Inch-by-148-ft Twisted Trimmer Line to see if that will provide more cutting power and last longer. Overall, though, I'm very impressed with this mower, and don't regret my purchase decision.

The trimmer arrived in good condition, and there was not really any assembly needed. The handle bar was not formed correctly, so the position clamping mechanisms don’t work well without some applied physical torque and tweaking. I filled the crank case with oil and added some fuel. The trimmer started right up and ran well. I put about 30 minutes of work on it before shutting it down for an oil change. Guess what? There is no oil drain plug on the engine, and the manufacturer recommends removing the fill cap and then turning the trimmer on its side to empty the oil reservoir. Nice... After making use of this new high tech oil draining method, you will be spending some time cleaning dirty motor oil off of the wheels and mower deck housing. After changing the oil, I decided to check the air filter. The filter was completely clogged with debris, so I removed it. The filter housing is of poor design and will require very frequent cleaning. Additionally, the filter housing is located right next to the wheel, which prevents removal and proper cleaning without removing the wheel. Another engineering marvel... The filter itself was already oil fouled and damaged, as it does not really fit the filter housing correctly. Brand new engine already puking oil into the carburetor? Sweet! I have attached some pictures for your review. These pictures were taken after only a couple hours of work on the machine. In the absence of an air intake screen, or pre-filter, I wouldn’t expect this engine to last very long. You will need to stay on top of the air filter cleaning, possibly a few times a day, and even that is not a long term fix. The string height is said to be adjustable, but I disassembled the string head and found only about one inch of travel up and down for height adjustment. I’m giving three stars for this trimmer due to the problems I have mentioned. Would I purchase this trimmer again with what I know now? Probably not. I think there are better options out there, even if some, (not all) of them cost a little more $$ 5 Year “Limited” Warranty? I strongly recommend that you read the warranty verbiage before making your decision. I would also recommend reading the one, two, and three star reviews of this mower before you decide to purchase it.

This is by far probably the best piece of lawn equipment I ever bought. Part of back yard has this slope and over grown with some kind of undesirable grass. It was horrible looking at it. A friend told me this what he uses on his pasture fence line. He said this would work better than my weed trimmer and man was he right. I added the oil, flew to the gas station and bought non ethanol gas. My intention was to make sure it worked, I couldn’t resist and went straight to that hill like our loose cat. I knocked down that tall grass in a matter of minutes about 20. I was so impressed I almost couldn’t stop cutting. This an amazing machine boys and girls trust me. Out of the box just simply set up your handle. I love the feature that you don’t have to shut it off when not actually trimming. Some others turn off the you have to restart. Not this one, It just sit an idle until you are ready to cut. It’s super light and easy to push. The mowing height can be adjusted as well. I didn’t adjust. Just let it down easy or you will be hitting dirt 🤗. I’m also laying sod no more tall weed grass. My babe was like man this looks great. You can do any job with the right tool(s). I want to use it again but the tall weed grass is gone for this year. Now I can see any snakes and other unwanted critters trying to hide out. Can wait until next year. Highly recommended product perfect gift ladies for your guy Christmas is almost here.

Very powerful mower! It was very easy to assemble. Though it is not a self propel mower, it was very easy to push through the grass. Cutting the grass was like using a hot knife through butter. I recommend this mower!
