When your mulch plug wears out or cracks, clippings scatter instead of being recycled back into your lawn. Repair Clinic stocks genuine OEM replacement mulch plugs and deflector chutes built to Murray's exact specifications—so your mower maintains its precision cutting action and model-specific fit and performance.
These cutting system parts are straightforward to install and restore your mower's efficiency in minutes. Don't settle for aftermarket substitutes that don't fit quite right.

A mulch plug blocks the deck discharge opening, forcing clippings back down into the blades for fine shredding. A discharge chute directs clippings out the side or rear. Your Murray uses one or both depending on the cutting mode—mulching or bagging. Swapping between them is simple once you know which holes align on your deck.
A cracked or improperly seated mulch plug allows clippings to escape the cutting chamber before they're fully processed. Check for visible cracks, warping, or loose fasteners. Also verify the plug seats flat against the deck—a bent chute or missing gasket breaks the seal.
Look on the frame near the handle, under the seat, or on the engine block. It's typically a 12–16 character code. Once you have it, enter it above to see all compatible deflector and mulch parts for your exact mower.
Not reliably. While some parts share bolt patterns, deck heights and chute angles vary by model. Using an incorrect chute causes poor discharge, uneven cutting, or poor mulching. Always verify compatibility with your model number first.

Murray typically places the model number on a label or decal on the mower frame near the handle, under the seat, or on the engine housing. Check these areas for a code that may combine letters and numbers, and copy it exactly, including dashes or spaces shown on the label. Type it into the search bar and the catalog narrows to parts made for your Murray mower, across every part category. If grass clippings are escaping, a damaged mulch plug or chute may be the issue, but the mower's model number is what confirms compatibility for the complete unit. This gives you an accurate match without sorting through parts for similar mowers.
