The 8" front and 10" rear high-quality wheels provide better traction and smoother maneuverability while cut grass is efficiently collected into the large 65L / 17.5 Gallon rear grass bag for fewer stops and improved productivity.

This gas-powered lawn mower that moves on its own is great for taking care of your lawn on the weekends and cleaning up the yard in the spring and fall. The 21-inch walk-behind deck covers a lot of ground, so you can easily get through grass without having to go over the same spot twice. Self-propelled drive makes things easier, especially when you're working on hills or uneven ground. It's easy to switch from a clean cut in the spring to a trim that's a little higher in the summer thanks to the seven-position height adjustment. The 4-in-1 design lets you switch between mulching, bagging, and discharging quickly, depending on how your lawn looks. Even when the grass is thicker after it rains, the engine power stays the same. You can still steer the car around trees, fences, and edges. The back bag is useful when you clean up in the fall and pick up leaves or clippings. It's easy to use and understand because the controls are easy to find.

This gas-powered lawn mower moves on its own and is made to do the same lawn care tasks over and over again with the same results. The 21-inch cutting deck covers a lot of ground, which speeds up the process of mowing medium to large yards. It is easier to walk on slopes and rough ground when you move yourself. You can cut the grass at any of the seven heights, so you can get it just right, whether you want it short or a little longer. It runs on gas, so it gives you reliable power for thicker grass and doesn't stop working a lot. Even people who don't use the controls very often can easily understand and use them. The mower works well on corners and edges when I do yard work once a week. The back bag is useful for picking up clippings after you've mowed. The build quality feels strong and like it can be used outside over and over again.

This mower feels sturdy and powerful. I used it on my backyard and was impressed by how smoothly the 170cc engine runs. The self-propel system saves effort on slopes, and the 21-inch blade covers a good area fast. It’s easy to change cutting heights and decide how to handle clippings. Perfect for anyone wanting quick, clean results every weekend.

I really like this self-propelled gas lawn mower. Our side yard is small and hard to reach, and the big riding mower is too bulky and awkward back there. This one handles it so much better. It cuts the grass quickly without a lot of effort on my behalf. The self-propelled drive makes a big difference on uneven ground and on the ditch bank. I just guide it, and it moves smoothly. The engine runs strong and steady, even in thicker patches. The large grass bag holds a lot before I need to empty it too - so I can get through the whole job and have hubs dump it when he gets home. The height adjustment is easy with the seven positions, and I can get the cut just right.

I've used it once so far and can't really complain, other than the "aridity" of the bag. Yes, it catches the hard debris but it allows far too much dust/dirt to escape in my opinion.

This gas lawn mower has been a great upgrade for maintaining a larger yard. The lawn mower 170cc engine delivers strong power and cuts through thick grass without slowing down. Compared to my old electric mower, this gas powered mower handles dense areas much more easily. The self propelled lawn mower feature also makes a big difference, especially when mowing on slight slopes or uneven areas. The 21 inch lawn mower deck covers a wide area, which helps finish the job faster. I like the multiple cutting options including mulching, bagging, and side or rear discharge depending on the situation. The large grass bag reduces how often I need to stop and empty it. It starts smoothly, feels sturdy, and overall makes mowing much more efficient.

The media could not be loaded. After reading all the reviews of this mower I purchased one. It was delivered on 4/2/2026 The mower can with oil in it, and the shippers packed it upside down, there was oil everywhere. Then the front wheel is broken. The owners manual has no contact information. Now the mower is strong and cut good.
