  • effortless mowing experience.
Style: 170cc OHV Engine
The media could not be loaded. I've been using the PowerSmart Self Propelled Gas Lawn Mower, and it's been a game-changer for my lawn care routine. The 21-inch steel deck provides excellent coverage, and the 170cc engine delivers impressive power, making mowing efficient and straightforward. One of the standout features is the 3-in-1 capability, allowing for mulching, bagging, and side discharge. This flexibility means I can adapt to different mowing conditions without needing multiple tools. The rear-wheel drive adds to the ease of use, especially on uneven terrain, giving me a smooth and effortless mowing experience. What I appreciate most is the durability and build quality. The steel deck feels sturdy, and the overall construction is robust, ensuring it will last for years. This mower has significantly reduced the time and effort required to maintain my lawn, and I couldn’t be happier with its performance. ... show more

  • Lightweight but not for thick grass
My mower went out so I needed to find an affordable one to use for a couple months. On the plus side, it is lightweight and easy to put together with a strong motor (144cc). Negative is the back guard is cheap and will not last and the side chute is small and easily gets stopped up. I've cut my grass three times. Normally I can cut my grass in 1.5 hours. With this mower, it takes me over 2 hours because it keeps getting jammed with grass and I have to stop, clear, and re-start. I first used the side chute. It is small and after about 20 feet it gets stopped up. Then after about 15 more feet the mower stops because it gets clogged with grass. I did not have this problem with my 125cc Murray motor. I have two areas in my yard where I planted zoysia grass. Those areas must be too thick with grass because the mower would get clogged and I have to walk very slow to prevent it from cutting off. Using the mulching option is pointless with thick grass. The guard on the back is thin and very flexible. If you pull the mower back, the guard will go under the blade. It lasted me 30 minutes before going under the motor and being chopped up. Luckily, it isn't needed because the back of the mower is low to the ground. This is the third mower I have purchased. It is the strongest but also it the most troublesome and the worst cut. Next year, I will be looking to see what Murray lawn mowers are on sale. Four months later, this mower is unusable. The plastic cannot handle the heat from the mower. One wheel broke off the front and the other is wobbly. The back guard broke off. I peg that holds the panel where the grass catcher attaches broke off so the panel can no longer be attached. The bottom of both sides of the handle at the bottom broke off. I contacted Amazon and PowerSmart was to get with me. They did not respond. The product is junk. It deserves less than one star. I wish I read the reviews at other sites. ... show more

  • Gas powered Lawnmower
Style: 170cc OHV Engine
Love that the thing comes basically fully assembled, had to pop the wheels on of course and stick the arm into the sockets (the part you actually hold while pushing) instructions are seriously simple a child could do it (provided you let them play with Legos occasionally) my fam has used this since the beginning of the summer for '24 and it's worked like a charm, it's a good amount of horse power and surprisingly easy to maneuver with the back wheel drive (feels a little funny the first time using it because it almost speeds away from you but it's really not too much to control, myself being taller it goes smoothly with my pacing and my dad being closer to average height neither of us had issues) not to mention it's a solid red colour and the appearance is about what you'd expect for a good quality mower. I anticipate getting at least 15 years out of the thing with being kept indoors when not in use (garage space or shed) would recommend if you aren't interested in getting an electric mower this one will def get the job done. ... show more

  • Follow directions and enjoy this great little mower
This is awesome LAWN mower I stress that this mower can handle any normal lawn. It is not a " back 40" mower What this mower is lightweight,powerful,maneuverable,fuel efficient. It is not all plastic, the body is steel, the plastic parts are not fragile, nor are they easily broken. The engine and drive shaft appear to be aluminum ( hence not a back 40 mower) Now my story... I ordered my mower to replace my broken mower, I received my mower quickly, assembled easily,oiled and fueled, she started first start. I mowed my yard and in an hour my mower had hit a baseball sized rock that was hidden in an overgrown patch of weeds. The mower stopped and seized the shaft was bent now here's the important part.. I was using the side discharge not bagging, both parts of the rock were held inside the mower they were not ejected! The mower body is not cheap, the engine is light not fragile and held together after hitting this rock. ( I will try to post pics) Now I was flummoxed to say the least, I got my paperwork expecting to get the runaround, I sent my information and all pertinent information to Amerisun ( the manufacturer) and in less than 12 hours got a personal response Amerisun immediately backed up their warranty and sent me a new mower, in one week ( today) I mowed my lawn again! Carefully checking for any debris. 👍 For general all purpose lawn I cannot recommend this mower or company enough they stood by their product. Buy this mower got nice lawn use this got an average lawn with crab grass buy this mower. Got a back 40 find another model from this company. Great customer service ... show more
