Product Features
The Reflex™ front-wheel-drive system pulls the RAZOR 21 DUAL BLADE forward at up to 3.7 mph, so you guide instead of push — great for larger lawns than a push mower can comfortably handle.
A dual-blade cutting system slices grass twice per pass for a finer, more even finish and better mulching — ideal for owners who want a manicured look without bagging every time.
The 21-in. (53.3 cm) deck adjusts from 1 in. to 4 in. across 7 positions, letting you fine-tune your cut throughout the season.
Backed by a 3-year residential / 90-day commercial warranty, the RAZOR 21 DUAL BLADE REFLEX is built for dependable, low-maintenance seasons of self-propelled mowing.

Switched from a single-blade Ariens push mower to this and the finish quality jumped noticeably. The self-propelled drive also saves my back on the slope in my backyard.

The Reflex drive is smooth and easy to control. Mulches beautifully with the dual blades — I rarely need to bag anymore.

Takes a little getting used to the extra weight from the dual blade deck but once you're moving it handles great. Cut quality is excellent.

This is my second Ariens mower and it's just as reliable as the first. The self-propelled system paired with dual blades makes quick work of my 3/4 acre lot.
