Caltric 42in Deck Mulching Kit Compatible with MTD Compatible with Cub Cadet 19A30006000 19A30006100 19A30006799

What It Is

This is an aftermarket mulching kit designed to convert a 42-inch cutting deck on compatible MTD and Cub Cadet lawn tractors from side-discharge or bagging to mulching. It replaces the discharge chute with a block-off plate and includes specialized blades and baffles to recirculate clippings for finer cutting.

Fitment & Compatibility

Before buying, verify your deck is exactly 42 inches wide (measured blade tip to blade tip). This kit is listed as compatible with MTD and Cub Cadet models originally using OEM part numbers 19A30006000, 19A30006100, or 19A30006799—check your owner’s manual or existing part number. It is an aftermarket alternative, not OEM, so fitment may vary slightly on older or non-standard decks. Measure your deck’s discharge opening width and bolt pattern for the block-off plate; the kit’s hardware may not match if your deck has been modified.

Key Things to Know

• Quality concerns: With a 1.0/5 rating from a single review, expect potential issues like poor fit, thin metal, or missing hardware. Inspect all parts immediately upon arrival.
• Installation difficulty: Moderate. You’ll need to remove the discharge chute, install the block-off plate, and swap blades. A socket set and torque wrench are required; follow the included instructions carefully.
• Common gotchas: The block-off plate may not seal tightly against older decks, causing clumping. Mulching blades included may be generic and require balancing before use. If your deck has a side-discharge deflector, you may need to remove it permanently.
• Performance: Mulching works best on dry, short grass (under 3 inches). Wet or tall grass will clog the deck, defeating the purpose.

Should You Buy It

This kit is only for budget-conscious DIYers who already own a compatible 42-inch MTD/Cub Cadet tractor and are comfortable with aftermarket parts and potential fitment tweaks. Given the extremely low rating and lack of reviews, skip it if you want guaranteed performance or easy installation—spend more on an OEM kit or a higher-rated aftermarket option.
