Briggs & Stratton 625ex Series

4-Stroke

The Briggs & Stratton 625EX is a 190cc <!-- verify: briggsandstratton.com --> 4-stroke overhead-valve engine in B&S's mid-tier consumer push mower range. The 625EX delivers more torque than the 550EX, better suited for thick or tall grass, slopes, and bagging operations. It uses a Walbro or Nikki carburetor <!-- verify: briggsandstratton.com --> and a Champion RC12YC spark plug. Annual maintenance: oil change (SAE 30 or 10W-30), air filter, spark plug. Carburetor float and main jet see increased wear on units used heavily in dense grass. One of the most commonly serviced mid-range push mower engines in North America.
