Briggs & Stratton ReadyStart Engine Technology Debuts on Riding Mowers

Ever since the engine experts at Briggs & Stratton first brought its ReadyStart® feature to walk-behind mowers in 2005, owners of riding mowers have longed to experience the same ease-of-start without the need to prime or choke the engine.

With the ReadyStart System now available on select Husqvarna riding mowers, the wait is over. ReadyStart is an automatic choking feature designed to start the engine within two 5-second cranking attempts in weather above 32 degrees. The ReadyStart System automatically senses engine temperature to deliver the right amount of fuel to the carburetor.

“Consumers want to know that their mower is going start with minimal effort each and every time,” says Carissa Gingras, marketing director for consumer engines and service at Briggs & Stratton. “A no-choke starting system, ReadyStart takes the guesswork out of starting the engine and we are the only manufacturer to bring this system to riding mowers designed for residential use.”

Featured on Briggs & Stratton’s V-Twin engines, the ReadyStart feature is mechanically driven and adds two major components to a traditional engine platform: a nylon air vane and a temperature sensitive bimetallic thermostat.

Available for purchase online at and local Husqvarna dealers, the following riding mowers feature the ReadyStart System:

  • YTH24V48 (Husqvarna FastTractor™)
  • YTH24V46
  • SmartSwitch™ Tractors – GT48XLSi and GT52XLSi
  • SmartSwitch™ Zero Turn Mowers – RZ46i and RZ54i

Engines equipped with the ReadyStart system are made in the USA of U.S. and global parts at the Briggs & Stratton plants in Auburn, Ala. and Statesboro, Ga. For more information visit
