    • Impressive 170cc Mower with an impressive price
Set name: 3IN1 Self-propelled Lawn Mower
The unit is surprisingly assembled in the USA. The motor is more than ample. Came almost completely assembled right out of the box. Solid instructions on the mower. It went nonstop mowing a slightly overgrown yard of 3/4 of an acre. Unit seems to be well designed. My only gripe and its not major is that is does not travel in self propelled mode as fast as I wish to travel. Motor didn't seem to hesitate in taller grass and didn't kill itself as most mowers do. While I certainly cannot say it will stand the test of time yet, 1st impressions are very good. For its price, I do recommend this unit ... show more

I would highly recommend for the price!!

Let's face it, it's the cheapest self propelled mower on Amazon. So let me tell you what I found after I assembled and mowed today. 1) Easy to assemble. (Although I had an extra screw in the bottom of my box, it didn't appear to be missing from anywhere). 2) Started on the first pull. 3) It did a good job mowing through my weeds/grass. Disappointing was the speed of the self propelled. But based on the purchase price I found it acceptable. It wasn't slow, but I am 65 years old and I can push it faster without self propelled. That being said, this mower is not that heavy, thus if you want to push it w/o self propelled I found it doable...which is helpful around flower beds, etc. My last mower was front wheel drive so the rear wheel drive takes a little getting used to. With the old one I could just lift the front wheels off the ground and pivot 90-180 degrees. It's not a big deal, again just takes a few uses to become 2nd nature. For the price, I thought it was an excellent purchase. I did buy the 3 year protection plan since it was a "no-name" mower and not returnable. It gave me a bit of peace of mind when I found that extra screw in the box. LOL. ... show more

    • Definitely a 5-star mower.
Set name: 3IN1 Self-propelled Lawn Mower
⭐⭐⭐⭐⭐ 5-Star Review – AMRISUN 21" Self-Propelled Lawn Mower I used my AMRISUN 21" self-propelled lawn mower for the first time today, and I’m seriously impressed. The 170cc engine has plenty of power and handled my yard with ease, even through thicker grass. The self-propelled drive makes mowing effortless, which is a huge plus if you have a medium to large yard. What really stood out was how well the mulching feature works. It chopped the clippings up super fine and spread them evenly across the lawn. I also tried the grass bag collection, and it filled efficiently without clogging. Switching between mulching and bagging was quick and simple. The mower feels solid, easy to maneuver, and starts reliably. For the price and performance, this mower absolutely exceeded my expectations. If you're looking for a powerful, easy-to-use mower with excellent mulching and bagging performance, the AMRISUN 21" is a fantastic choice. Highly recommend! Definitely a 5-star mower. ... show more

    • Amrisun 🎯
Set name: 3IN1 Self-propelled Lawn Mower
This unit is a beast. I like it a lot. Powerful and, in my case, powered through shin height vegetation with no lag. My property is pretty much all incline and had no issue with mowing, but my legs got tired to complete it in 1 day(1acre) It did jerk out of my hand a time or two and I let go of start lever and had to keep re starting it but it was an operator issue not the machine. I will say it’s heavy and if the self propelled part ever stopped working it would be a tank to push. I hope the plastic wheels last. This unit replaced a Troy bilt and the rear plastic wheel broke off. Try mowing with 3 wheels… ... show more

    • Problem mower
Set name: 3IN1 Self-propelled Lawn Mower
Thus lawnmower on day one of use took at least 12 hard pulls to start only cut half my yard before cutting off and would not start again, the self propel is over powering jerking you forcibly forward. Wanted to return and it didn't seem to be an option. Was ready to fight with Amazon concerning the difficulty with the return option. Got another try today took another 10 hard pulls was able to finish the cut being perked around trying to control the mower. Don't think this going to work out for me, it's just too much to handle. ... show more
