Features

  • POWERFUL 200CC 4-STROKE OHV ENGINE BUILT TO TACKLE ANY YARD - Powered by a robust 200cc overhead valve engine that delivers consistent, reliable power through thick grass, wet conditions, and uneven terrain. No mixing oil and gas - the 4-stroke engine runs cleaner, starts easier, and lasts longer than 2-stroke alternatives, making it the ideal gas lawn mower for residential use.
  • 3-IN-1 VERSATILITY - MULCH, BAG, OR SIDE DISCHARGE - Adapt to any mowing condition with three cutting modes in one machine. Mulch clippings back into your lawn for natural fertilization, collect them in the included rear bag for a clean finish, or side discharge for fast mowing of overgrown areas. Switch between modes quickly and easily without extra tools or attachments.
  • SELF-PROPELLED REAR-WHEEL DRIVE HANDLES HILLS AND LARGE YARDS WITH EASE - Stop pushing and let the mower do the work. The self-propelled rear-wheel drive system gives you superior traction on slopes, hills, and uneven ground, reducing fatigue so you can cover more ground with less effort. Perfect for larger residential yards and challenging terrain.
  • 7-POSITION SINGLE-LEVER HEIGHT ADJUSTMENT - Dial in your perfect cut with a convenient single-lever height adjustment system offering 7 positions. Whether you prefer a close crop or a taller, healthier lawn, switching between heights takes just seconds - no bending down, no adjusting individual wheels.
  • DURABLE STEEL DECK BUILT FOR THE LONG HAUL - The heavy-gauge steel cutting deck resists denting, warping, and cracking season after season - far outlasting mowers with plastic decks. At 21 inches wide, it covers more ground per pass, cutting down your mowing time while delivering a clean, professional-looking cut every time.

Description

The Powerhorse 21in. 3-in-1 Self-Propelled Gas Lawn Mower delivers added power and easier handling for larger, sloped residential lawns. A high-output 200cc 4-stroke engine provides consistent cutting performance across a 21in. cutting path, while a 7-position single-lever height adjustment sets cutting heights from 1in. 3in. The 3-in-1 deck supports mulching, rear bagging or side discharge to adapt to changing lawn conditions. A rear-wheel-drive self- propelled system helps maintain steady forward motion and traction on slopes, and the big-wheel layout with 8in. front wheels and 10in. rear wheels supports smooth, confident handling. A 1.2-gallon fuel tank is sized for extended mowing sessions on 1+ acre lawns, and an easy recoil start keeps operation straightforward. Built for demanding residential use, the Powerhorse 21in. 3-in-1 Self-Propelled Gas Lawn Mower is backed by a 2-year limited warranty.

  • Awesome mower
Awesome mower...reasonable price. Works very well. Easy for older person.

  • Self-propulsion stopped working
Drive wheels were great, until they weren't. I *JUST* got this mower TODAY! Mowed my small front & side yard with zero issues on a medium height. Drive kicked it with a lot of power, which is the reason for my purchase, being a 100% disabled army veteran. I was going to take it out back to work on the backyard, when I decided to try it a bit shorter to see how it handles it on the side alongside my driveway again, going slightly downhill. Wheels powered on with ease, & I let go of the clutch rod to slowly turn it around to go back up after 1 pass. Gripped the clutch bar again, and the rear wheels no longer moved. No power. Lawnmower ran, but it just became a heavy 200cc push mower. I got this to replace my push mower due to medical reasons (I am a 100% disabled army veteran & need to conserve my energy & my bad back & I overheat & my blood pressure drops & I faint/vomit). Called the number in the manual and they told me I needed to call a different number for tech support, and they had just closed 8 minutes before I called at 6pm CST. This item is obviously non-returnable; it has fuel & oil in it. I tilted it in its side; no broken links & the clutch arm to the transmission block moves with the cable when the lever is pulled (I had my son's help to verify it moved from the handle bar), so I think the clutch or something inside went bad after only 15 minutes of run time. I have been mowing lawns with & without self-propulsion drives for 40 years, since I was 10 (I'm 50 now). I have NEVER had a brand new lawn mower ever do this! VERY disappointed! A waste for $300. So I wait. I think the transmission gear box is bad. I will update this. There is a Northern Tools location in my area. I really do like the engine power & I DID like the self-propulsion. This mower is non-returnable. I will update later. ... show more

  • Quality
This type of machine is very easy to use, powerful, and operates very smoothly.

  • Disappointed..
Literally have only used the mower 2 times since delivery and on the first use the side shoot flew off and broke the clip off it’s cheaply made plastic, so now it cannot go back on. The plastic hub cap flew off and cracked a piece out of it instantly it didn’t even last through two rows of grass cutting. Than the biggest issue like other reviewers have stated the self-propelled sucks. It goes so slow. My spouse has a rod in his hip and leg from breaking his hip two yrs ago and it’s even too slow for him. It’s at a turtle’s pace.. which takes way longer than it should to mow your lawn, it is really ridiculous for the price paid. I will be reaching out to customer service about these issues since there’s a 2 yr warranty on the mower. ... show more

  • Cautious purchase advised.
This mower leaves something to be desired. First mow out of the box and I think the blade came pre-dulled. Second mowing attempt and the rear- wheel drive stopped working....it was easy to assemble and starts well. Unfortunately I passed my window for return and stuck with a major problem.
