AMERISUN brings a straightforward approach to gas-powered mowers. The AV8621S1 is a 21-inch self-propelled model with a 170cc engine and rear-wheel drive. That combination matters more than you might think. Rear-wheel drive gives you better traction on slopes and uneven ground compared to front-wheel systems. It pulls the mower forward rather than pushing it, which feels more natural when you’re climbing an incline.

The engine uses an auto choke system. That means no fiddling with a lever or priming bulb before starting. You pull the cord and it catches. The forced air cooling keeps the engine running consistently even during longer sessions in summer heat. The single-lever height adjustment gives you six positions, from a low 1-inch cut up to 3 inches. That covers everything from a tight golf-course look to a more relaxed lawn.

The 3-in-1 design lets you bag, mulch, or side-discharge clippings. The reinforced steel deck and heavy-duty blade handle thick grass without bogging down. One thing to note: at 170cc, this is a solid middle-range engine. It will handle a standard suburban lot without issue, but it’s not built for commercial-grade abuse or overgrown fields. For weekly mowing on a quarter-acre or less, it’s more than capable.
