STIHL RM 453 T 21" Gas-Powered Self-Propelled Single-Speed Lawn Mower

The STIHL RM 453 T is a gas-powered, self-propelled walk mower designed for homeowners who want dependable, no-fuss power to maintain a large lawn without adjusting drive speed on the go.

Single-Speed Self-Propel

A single-gear drive moves the mower at a steady, fixed pace, which keeps operation simple for anyone who prefers a consistent walking speed over a variable control.

Robust Polymer Housing

The housing is built from durable polymer that resists dings and corrosion, keeping the mower looking and running well season after season.

Easy-Start System

Like other mowers in the STIHL lineup, the RM 453 T uses an easy-start pull system tuned for reliable starts in both cold and warm weather.
