45L Grass Catcher

The HYM40LI420SP mower uses a powerful 40v motor, with a cutting width of 415mm, it's suited for medium to large-sized lawns. It also features a spacious quick release 45L easy airflow grass catcher with a hard lid, meaning you spend less time emptying the cuttings and more time mowing.
