A bag, a frame, and a model number that has to match
Replacement grass catchers, compared
The grass box is the part of a mower that fails first and is thrown away most often, usually because the fabric has rotted where wet clippings sat against it or because a corner of the frame has snapped. This shelf replaces it, and the purchase turns almost entirely on the fits column: a catcher hangs on a specific mower deck, and Honda HRU214, Einhell GE-HM 300, AL-KO Razor Cut 38.1 and Gardena cylinder machines all appear here by name. Nothing about a catcher is standard — not the hook spacing, not the mouth width, not the angle it hangs at — so a listing that names no machine is unusable however well it is described. The volume is the second figure, 35 to 60 litres on domestic mowers, and it is a property of the mower rather than a choice: a bigger box on a small deck does not fit. What does vary is the material and the frame. A rigid plastic box empties cleanly, survives being dropped and blocks airflow least when it is half full; a fabric bag on a steel frame folds away, weighs less, and clogs as soon as the mesh is coated with wet grass. Several listings here sell the bag alone, without the frame, for people replacing only the worn half — which is cheaper and only works if the frame is sound. Finally the indicator: a flap or a vane that drops when the box is full. It is a small feature that decides whether you learn the box is full from a gauge or from the trail of clippings behind you. We compare volume, material, frame, fits and indicator.
