Are corded electric mowers powerful enough for thick grass?

For routinely maintained lawns the consensus across reviewers is yes, but most corded mowers in the 11-13 amp range will bog down or trip their overload protection in tall, wet, or overgrown grass. Reviewers who let grass get long report having to slow down or make a second pass, and r/lawnmowers threads specifically flag the higher-amp Black+Decker models for shutting down when fed too much at once.
