- POWERFUL 140CC B&S ENGINE:Equipped with the trusted B&S EX550 engine, this lawn mower delivers unmatched power and precision. With its easy-pull recoil and auto choke system, starting is effortless and stress-free.
- 3-IN-1 VERSATILITY:Switch effortlessly between EFFICIENT BAGGING, NATURAL MULCHING & REAR DISCHARGE. Bagging collects clippings neatly into a large-capacity grass bag, keeping your lawn clean and tidy. Mulching finely shreds grass clippings and redistributes them to enrich the soil, reducing the need for fertilizer. Rear discharge quickly expels clippings from the back, ideal for covering larger areas without interruption.
- ROBUST STEEL DECK:Crafted from heavy-duty alloy steel, the 21-inch cutting deck ensures long-lasting durability and efficient mowing. It covers large areas quickly, making lawn care less time-consuming and more effective.
- CONVENIENT INSTANT START:Simply pull the cord to start no need to press a primer bulb! Quick and easy ignition gets you mowing in no time.
- ADJUSTABLE CUTTING HEIGHTS:Featuring 6 height settings, this mower adapts to your lawn's needs. Whether you prefer a clean, low trim or a lush, higher cut, it's easy to customize for every season.

It has no problem cutting tall and hard clumps of grass. The self propelled feature seems to work great and makes cutting way easier. It also starts with ease and is easy to use overall. The blade seems to be in good shape even after hitting some branches, and still cuts great after alot of use. The only slight downside is that the wheels are plastic and dont have as much grip as rubber wheels, but you could probably replace them. Also, I wish the gas tank was a bigger, but it has good gas efficiency and I couldnt complain for the price. Overall, it's great, inexpensive and fun to use. No problems as of now, and has no trouble cutting alot of grass.

Like I said, the lift lever was found in the bottom of the box. We bought this in February and it's past time to return. The box arrived undamaged so we assumed everything was OK. The mower has no damage to explain how this lever broke off. The wheels. The deck are perfect. Now, let the fun begin. I call customer service. It has a 2 year warranty. Well I need to register it before I can order the part. So, I make a second call and send them the receipt and information they need. Now, I don't know if and when they will send the part. But on closer inspection, this part was riveted on. There's no way I can get the end out to put a new one In. The wheel will have to be taken off and the broken piece remaing drilled out. This is factory work. I can't do this myself. I don't have the tools. My husband and I are not in the best of health. That's why I wanted self propelled. It's a small yard and I thought it would be manageable. It would if the mower worked. Well it does. I bought gas and oil and started it up before realizing there was no way to lift the deck. It started the first pull. I worked in small engine parts and repair. Mowers were the main business along with chainsaws. I know the work needed here. It's not an easy fix. Meanwhile, my grass has that spring growth spurt going on. So I was faced with hiring a lawn service or getting another mower. I rented one just to get my lawn in order before the city slaps a fine on me. Yes, they do that here. And the one I rented did a fine job. The best first cut I've ever seen. I did all this after coming home from work. It was a long day but had to be done. I'll update if it's needed. But that's my story with this mower. It does start on a dime. I'll give it that. But I'm not happy being out $400.00.

Our new lawn mower arrived 2 days early and in great condition! Thanks UPS. We checked our instructions and were delighted to find it was easy to assemble. Starts on the first or second pull. It cuts very well. We have about a 1 1/2 acre yard and it tends to be wet (swampy). The tires did not get great traction in the really wet areas, but everywhere else it did just fine. The self-propel is very responsive. Also, a note**, they recommend you use regular 10W-30 oil, which was different from my previous mower, which had a combination of oil and gas mix. This is more convenient, as I can get that anywhere. Also, took advantage of the five payment plan, no interest, any credit card. That was a big help!

I ordered this lawnmower through Amazon, and I was so disappointed because like other reviews, the lover that raises and lowers, the deck was broke off. I immediately called the company rather than Amazon to see if I could get a replacement part they were on back order. So I then called Amazon and the representative that I visited with was more than helpful. He offered me a full refund and keep the lawnmower or I could keep the lawnmower and he’d send me a new one free of charge. I wasn’t really expecting that, but it was more than what most companies do. I do like the lawnmower, especially for the price point. It does a great job and it’s easy to start up usually on the first pole.

Very the happy with this mower. Starts on the first pull, the self propell doesn't drag you along nice easy pace and cuts well, I like not having the side discharge.
Reviewed in the United States on August 4, 2025 by Brad J
No side discharge, the rear discharge clogs easily. With in two weeks, the rear stripped plastic came apart from the mower. I really dislike it. It does mow, but…. Shop around, there has to be a better mower for the money. Value for money: Not so much Speed: No adjustable speed control, moves to slow for me.

POS. Do not buy!!!! Clogs up at rear of deck, lever to raise and lower deck pops out of place and drops to lowest setting constantly, self propel pretty much drags you. Almost impossible to control. Extremely disappointed. Waste of money!!
