Sam Rourke
Sam Rourke is the maintenance & care editor at Mower Mentor. Sam covers the routine, preventive side of mower ownership: oil changes, blade sharpening and balancing, air-filter and spark-plug tune-ups, deck cleaning, fuel care, winterizing and spring start-up, and the by-the-hours maintenance schedules that tie it all together. Sam came to this work through fifteen years of small-engine service, holds Equipment & Engine Training Council (EETC) certification, and has run a Briggs & Stratton and Honda GCV service bench long enough to know which maintenance steps actually matter and which are dealership upsells. Every procedure on the site is one Sam has done on a real machine, photographed step by step, with the torque values and part numbers that the manual buries. Sam's own fleet - a gas walk-behind, a battery mower, and an aging riding mower - is the documented test bed for the maintenance calendar. Sam lives in the US Great Lakes region.
