8TEN Mulch Kit for Cub Cadet ZT1 ZT2 ZTS1 ZTS2-50 Troy Bilt Super Bronco 50XP 50-Inch Deck 19A30050100 (Toothed Mulching)

What It Is

This is a toothed mulching kit designed to convert 50-inch deck Cub Cadet ZT1, ZT2, ZTS1, ZTS2, and Troy-Bilt Super Bronco 50XP mowers from side-discharge or bagging to fine-cut mulching. It replaces the standard discharge chute with a baffle and uses specially shaped blades to chop clippings multiple times before they settle into the turf.

Fitment & Compatibility

Before buying, confirm your mower has a 50-inch fabricated deck (not stamped). This kit fits only the following models with a 50-inch deck:

• Cub Cadet ZT1, ZT2, ZTS1, ZTS2 (50-inch models)
• Troy-Bilt Super Bronco 50XP (50-inch)
• OEM part number cross-reference: 19A30050100

Measure your deck width—if it’s 50 inches and uses a single center discharge chute, this kit should mate up. It will NOT fit 42-inch, 46-inch, or 54-inch decks. Check that your current spindle spacing matches the provided blade holes (typically 3-point star pattern). The kit includes three mulching blades, a baffle plate, and hardware. If your deck has a different spindle bolt pattern, you’ll need a different kit.

Key Things to Know

• Installation difficulty: Moderate. Requires removing the deck, swapping blades, and bolting on the baffle. Plan 45–60 minutes.
• Blade quality: 8TEN blades are aftermarket steel, not OEM. Some users report they’re slightly thinner than factory blades, which may reduce lifespan under heavy use.
• Mulching performance: The toothed design cuts clippings finer than standard mulching blades, but only works well with dry grass. Wet or tall grass will clump and require slower mowing.
• Common gotcha: The baffle may interfere with some bagger attachments—check clearance if you plan to switch between mulching and bagging. Also, the kit does not include a mulch plug for the discharge opening; you may need to buy one separately if your mower doesn’t have it.

Should You Buy It

Buy this kit if you have a compatible 50-inch Cub Cadet or Troy-Bilt ZTR and want to mulch without buying OEM parts. It’s a good budget option for homeowners who mow regularly on dry lawns and don’t need OEM durability. Skip it if you need maximum blade longevity, plan to mulch wet grass, or have a non-50-inch deck.
