Ne changez plus jamais votre lame de tondeuse !

Does your lawn turn yellow a few days after mowing? Does the grass look like “straw” with frayed fibres? It’s not the sun. It’s not the heat. It’s your blunt mower blade tearing and ripping the grass instead of cutting it — and that opens the door to lawn diseases.
