Detailed Description
Engine & Performance
This mower is driven by a 144cc 4-stroke OHV mower engine designed for dependable starts and steady torque during mowing. The auto choke system makes initial pulls easier—great for users who don’t want the fuss of priming—and the forced air cooling keeps the engine running cooler during longer sessions. For those who search for a “144cc OHV push mower ideal for medium yards“, this model is positioned well.
Deck, Cutting & Versatility
The 21 inch lawn mower steel deck offers rigidity and consistent cutting height across the blade span. As a 3-in-1 21″ mower with bagging mulching and side discharge, you can switch modes depending on season and yard needs. The included 1.4 bushel grass catcher gas mower is handy for post-mow cleanup, while the mulching plug helps return nutrients to the soil when desired.
Height Adjustment & Maneuverability
Adjusting the cut is straightforward with the single lever and six positions (1.5″–3.9″). The larger rear wheels and ball-bearing axles make this push lawn mower easier to guide through uneven lawns and over small bumps—useful if you’re searching for a 6 height adjustment gas mower for uneven lawns.
