With a 40 L collection bag, the Mountfield mower has plenty of space for grass, even when the grass is damp. Storage is simple and space effective thanks to the foldable handlebars and collapsible textile grass bag. I was disappointed that this mower didn’t have adjustable handle heights. Being petite, it always helps when I can lower the handles to make the mower more comfortable to push, but this model isn’t designed with that option. That said, the handles fold over easily, making it convenient to store the mower.
