MTD Genuine Parts 19A30006OEM Mulching Kit for 42-inch Cutting Decks (2009 – 2011), Black

What It Is

This MTD Genuine Parts mulching kit (19A30006OEM) converts a standard 42-inch side-discharge mower deck into a mulching deck, recirculating clippings for finer cutting and natural lawn feeding. Designed for select MTD, Cub Cadet, Troy-Bilt, and Yard-Man mowers with 42-inch fabricated decks built between 2009 and 2011.

Fitment & Compatibility

Before buying, check three things: your mower’s deck size (must be exactly 42 inches), model year (2009–2011 only), and deck type (fabricated steel, not stamped). This kit fits specific models from MTD, Cub Cadet (e.g., LTX 1042, RZT 42), Troy-Bilt (e.g., Bronco 42), and Yard-Man. Confirm your mower’s model number matches the official MTD compatibility list—common mismatches include 46-inch decks or post-2011 machines. The kit is OEM (not aftermarket), so it bolts directly to existing deck mounting holes without modifications. Measure the deck’s spindle-to-spindle width and baffle clearance if unsure.

Key Things to Know

• Quality: OEM build with durable steel baffles and a stamped mulch plug; holds up well under regular use, but check for rust on older decks.
• Installation: Moderate difficulty—requires removing the side-discharge chute, bolting on the baffle kit, and attaching the mulch plug. Plan 30–45 minutes with basic hand tools.
• Common gotcha: The kit may not include blade upgrade instructions. For best mulching, pair it with MTD’s high-lift mulching blades (sold separately) to avoid clumping.
• Fitment nuance: Some 2010–2011 models have a slightly different deck bracket; verify your deck has the pre-drilled mounting holes for the baffle—if not, you’ll need to drill.

Should You Buy It

If you own a 2009–2011 MTD-family mower with a 42-inch fabricated deck and want to reduce bagging frequency while feeding your lawn, this kit is a solid, OEM-fit upgrade. Skip it if your deck is stamped steel, if you prefer aftermarket for lower cost, or if you need a blade set included—budget extra for those separately.
