631-05195A Tractor Mulching Cover Kit Compatible with Troy-Bilt TB46 Craftsman T2100 Cub Cadet RZT-42, XT1-LT42 & XT2-LX42 42" & 46'' Lawn Mowers Decks, Replaces for 631-05195

What It Is

This mulching cover kit blocks the discharge chute on your lawn mower deck, forcing grass clippings to recirculate and cut into fine mulch. Designed for 42" and 46" decks on Troy-Bilt TB46, Craftsman T2100, and Cub Cadet RZT-42, XT1-LT42, and XT2-LX42 tractors.

Fitment & Compatibility

Measure your deck width first—this kit fits 42" or 46" decks only. It replaces OEM part 631-05195. Check your mower’s model number (under seat or frame) against these series: Troy-Bilt TB46, Craftsman T2100, Cub Cadet RZT-42, XT1-LT42, XT2-LX42. Not universal; does not fit 50" or 54" decks. Aftermarket part, so verify your deck’s chute opening shape matches photos—some newer models use a different latch design.

Key Things to Know

• Material: Heavy-duty plastic with metal latch pins. Holds up to normal use but can crack if you hit rocks or stumps.
• Installation: Tool-free—snaps onto existing chute bracket. Takes 2–3 minutes. Ensure spring-loaded pins click fully into place or it may rattle loose.
• Common gotcha: If your deck has a factory-installed mulching plug, this kit is redundant. Also, it does not convert side-discharge decks to mulching; you need a separate mulch blade set for best results.
• Return policy: Check seller’s return window—some aftermarket kits have poor fit on older deck revisions.

Should You Buy It

Buy this if you own one of the listed 42" or 46" models and want a quick, cheap way to mulch clippings instead of bagging. Skip it if you already have a mulching plug or need a complete mulching system (blades + plug). For $18, it’s a solid low-risk upgrade for occasional mulching.
