Take down the sound.

Briggs & Stratton QPT Push Mower Engine

You want quieter power. We Deliver.

You want the freedom to mow early morning or late evening, without disturbing the neighbors. Or maybe you just prefer a quieter mowing experience. Well, we put our engine design team on it.  Quiet Power Technology™ delivers lower sound levels and less vibration.  So now you can confidently mow your lawn on your own schedule.

How Does QPT Work?

To reduce the decibel level of the engine, Briggs & Stratton engineers made changes to the speed governing and fuel systems. In addition to the engine development, Briggs & Stratton partnered with lawn mower manufacturers to develop quieter mower blades to further improve the sound quality. The result? A quieter lawn mower by up to 65%**.

Quiet Power Technology Engine Features

  • Up to 65% quieter
  • Less vibration, smoother operation and more comfort
  • 7.25 ft lbs of gross torque to cut through tall, thick grass
  • ReadyStart® Starting system-no prime, no choke just pull for power
  • Commercial-Grade Air Management System to reduces harmful yard debris.

NEW for 2016: Quiet Power Technology™ Featuring Just Check & Add™

How does Just Check & Add work?
There are two major reasons consumers usually need to change their oil:

  1. Debris has gotten into the oil, causing it to get dirty. Dirty oil causes wear on the engine.
  2. And through regular running of the engine, the oil heats up, causing it to breakdown and create sludge.

The Just Check & Add feature uses an automotive-style paper air cleaner element with a press-fit design to keep dirt out of the engine, and an improved oil fill tube with extended flange to protect the tube from debris during routine oil checks.

Additionally, the Overhead Valve and its innovative scroll design and cooling package help the engine run cooler, reducing the oil temperature. Cooler oil means slower decay and breakdown of the oil.

Now homeowners will enjoy the same great power to take care of tall, thick grass but without the worry of a noisy lawn mower or regular oil changes.
