Genuine OEM Toro 42" Timecutter Part # 137-5034 Mulch Plug Cover

What It Is

The Toro 137-5034 is a genuine OEM mulch plug cover designed to block the discharge chute on 42" TimeCutter zero-turn mowers, converting them from side-discharge to mulching mode. It traps grass clippings inside the deck for finer cutting and better nutrient recycling.

Fitment & Compatibility

• Deck size: Fits only 42" (107 cm) Toro TimeCutter decks. Do not use on 50" or 60" models.
• Model check: Compatible with TimeCutter SS, SWX, and MyRide series (e.g., 75740, 75742, 75760, 75764). Verify your mower’s model number on the frame tag.
• OEM vs aftermarket: This is genuine Toro, so bolt pattern, latch fit, and seal are guaranteed. Aftermarket plugs may require modification or leak clippings.
• Measurements: The plug is ~14" wide with a molded rubber gasket. Measure your deck’s discharge opening width (should be ~13.5") before ordering.

Key Things to Know

• Quality: Heavy-duty ABS plastic with UV-resistant rubber gasket. Holds up well to sun and impact, but the latch spring can corrode over time.
• Installation: Tool-free—slides into the discharge opening and locks with a metal lever. Takes under 2 minutes. No deck removal needed.
• Common gotchas: The latch tab on older decks may be worn; if the plug rattles loose, replace the latch spring (part 137-5035). Also, mulching requires sharp blades—dull blades will leave clumps.
• Performance: Works best with Toro’s mulching blades (sold separately). Standard blades will produce coarser clippings.

Should You Buy It

Buy this if you want a perfect OEM fit for your 42" TimeCutter and prefer mulching over bagging or side-discharge. It’s ideal for frequent mowing in dry conditions where fine clippings decompose quickly. Skip it if you only side-discharge or bag, or if your deck latch is already damaged (fix that first).
