Many people mistake those seed heads that are popping up all over our lawns as weeds. This is just your grass doing it's thing - but those seed heads are very thick. It's time to sharpen your blade and we show you new technology to get it done right. You might take sharpening your blade, once every ten hours as recommended, as an afterthought (and judging by the fact that many of us never sharpen our mower blade!!!!) BUT it is essential to having a great lawn and keeping your mower running smoothly.
