Short answer

For a Cub Cadet lawn tractor or zero-turn with a 42-inch deck that already has mulching blades, Cub Cadet's 19A30055100 plug kit is the listed part.[1] If you need blades too, the 19A70041GFP kit for 42-inch decks includes two mulching blades, a baffle and hardware.[2] For a John Deere 42A deck, it is the BUC11053 MulchControl kit.[3]

How we chose

A kit is on this list only if:

  1. Its maker names the deck and the mowers it is for. Cub Cadet lists its 19A30055100 for Cub Cadet and battery lawn tractors and zero-turn mowers with 42-inch decks, and as compatible with the Troy-Bilt Super Bronco 42E XP and Mustang Z42E XP.[1] John Deere's BUC11529, a lever-action MulchControl kit, is listed for the 42A deck on the Z370R Electric.[4]
  2. Its maker states what is in the box. The 19A30055100 includes one molded plug and mounting hardware.[1] The 19A70041GFP includes two mulching blades, a mulch baffle, mounting hardware and instructions.[2] Where a maker gives no contents list, as with Deere's BUC11053, we say so.
  3. Size alone never qualifies. Troy-Bilt's 21-inch hinged mulch plug 687-06029 replaces 687-02516, 687-02516A, 987-02516 and 987-02516A, and gives no model list.[5] A kit or plug fits only through those numbers or a maker's model list.
  4. The product is approved in our catalog, from the brand's store or one it links.

On 2026-10-17 five kits and plugs met this bar. Craftsman's CMXGZAMA70041 contains two mulching blades, a molded plug and mounting hardware,[6] and EGO's AMP4200 plug is listed for its 42-inch Z6 zero-turns and T6 tractor.[7] On 2026-10-19 we added larger decks: Cub Cadet's 46-inch kit holds two mulching blades, a mulch baffle, hardware and instructions,[8] its 19A30042100 for 54-inch decks holds three mulching blades, a molded plug and hardware,[9] and John Deere's BUC10705 is the MulchControl kit for the 48A deck.[10]

Some kits are a plug and hardware only, with no blades listed.[1] On 2026-10-27 we added two Oregon Gator G3 mulching blade sets for decks that already have their plate: the D-42-2G, two 21-inch blades for a 42-inch deck with the Husqvarna YTH18542 on its fit guide,[11] and the 96-370, a 22-7/8-inch blade whose fit guide includes the Husqvarna YTH21K46.[12] They hold no plate, plug or baffle.

Oregon sells the 92-615 as a set of two 21-3/8-inch Gator G3 blades for a 42-inch John Deere deck, 2.50 inches wide and 0.203 inch thick with a 7-point star center hole, replacing GX22151, GY20850 and AM141033 among others, for the D100 to D130, E100 to E130, S100 to S240 and X105 to X310 among others.
Watch out
Blades only, with none of the baffles or discharge closure that John Deere's BM21816 includes; match your old blade number to Oregon's list. Oregon states no cut direction. On Amazon, check that 'Ships from / Sold by' shows Amazon.com or Oregon.

Limits to keep in mind

  • Mode switching. On the BUC11053, Deere says the MulchControl baffle opens and closes with a lever on top of the deck, and that the system still mulches about one third of the material in side-discharge mode.[3] That third is Deere's figure, not a measurement by anyone else.
  • Bagging. John Deere says the rear MulchControl baffle on the S240's 42-inch Accel Deep deck must be removed to install the bagger chute.[13]
  • "Most". Cub Cadet's wording for the 19A70041GFP is "most" CRAFTSMAN, Cub Cadet and Troy-Bilt riding mowers and RZT models with a 42-inch deck from 2015 on.[2] Check your model.

For background, see mulch plug vs mulching kit and John Deere MulchControl kits.

Questions

Which Cub Cadet 42-inch mulching kit includes blades?

The 19A70041GFP includes two mulching blades, a mulch baffle, hardware and instructions. The 19A30055100 includes one molded plug and mounting hardware, with no blades listed.[2][1]

Does the John Deere BUC11053 include blades?

Deere's page does not list the kit's contents, so it does not say. Check with a John Deere dealer before you order.[3]

Can I still side-discharge with MulchControl?

Deere says its MulchControl system still mulches about one third of the material in side-discharge mode, switched with a lever on top of the deck. That is Deere's own figure.[3]
