In 2017, Briggs & Stratton’s Just Check & Add technology will be available on more walk mowers across more brands as the company brings the innovation to its 625ex Series engine. Just Check & Add simplifies lawn mower maintenance, as owners no longer need to change the oil — simply check and add when needed (under normal use conditions). Engineers at Briggs & Stratton designed the engines to keep the oil cooler and cleaner, eliminating the need to change it. The automotive-style paper air cleaner element and the improved oil fill tube with extended flange protect the engines from debris, keeping the oil clean. Additionally, the overhead valve design with its innovative scroll design and cooling package allows the engines to run cooler and reduces the oil temperature.
