Engine, deck width and which wheels drive · review
A 21-inch steel-deck push mower that folds for storage, with mulching and side discharge, 10-inch rear wheels and a single-lever height adjuster.
PowerSmart puts a 144cc OHV engine with an auto choke on a 21-inch steel deck. The price is about $70 above its 18-inch mower, and the weight is almost the same at 59.4 pounds, so the wider deck is the better buy for most lawns.
A single lever sets 6 positions from 1.5 to 3.9 inches. Ignore the details table, which lists the two numbers the wrong way round. Rear wheels are 10 inches, a real help on bumpy ground compared with the 7-inch SENIX.
The handle folds and the listing claims up to 70% less space. No folded size is published, so measure from the mower itself if the shed is tight.
Stop the engine and let the blade come to a complete stop before you clear the chute or reach under the deck. Fuel and oil handling is covered in the maker’s manual, and that manual outranks this page.

No. The listing calls it a 2-in-1 steel deck for mulching and side discharge.
PowerSmart says up to 70% of storage space. That is the seller’s figure, and the listing gives no folded dimensions.
7.8/ 10
The sensible middle of the gas push class: a full-size deck with big rear wheels. Skip it only if you need a bag.
A flat quarter-acre yard where the mower has to be stored in a tight shed.

The biggest engine among the push mowers here: 201cc and a stated 9.0 ft-lb of torque, on a 3-in-1 deck that weighs a heavy 81.9 lb without drive.
Best for: A flat lawn that gets tall between mowings, where torque matters more than weight.
≈ $300
144cc OHV gas · 18 in cut · push · 1.5 to 3.9 in · side discharge only · 58.4 lb · 2-year warranty
An 18-inch steel-deck push mower with side discharge only. It is narrow enough for tight yards, but heavier than the wider SENIX push model.
Best for: A small yard with tight gates or corners where an 18-inch deck fits and a 21-inch does not.
≈ $200
