The INSTART version of the HM53A features an electric starter. Constructed on the proven Grin chassis, it has all the HM46 features but is mounted with the powerful and reliable Briggs & Stratton 5.5 HP 675 series engine with INSTART. This innovative engine has a Lithium Ion battery that makes it possible to start without pulling a cord. Instead, just press a button.
The battery allows more than 50 start ups with one complete charge.
The starter battery is completely charged in about 60 minutes, while more than 10 start ups are possible with just 10 minutes of charging. Instart is a true revolution in the field of lawn mower engines.
