Brand John Deere


42C mulching kit from John Deere. The mulching attachment for the 42-in. mower provides excellent performance. This is a high-performance mulching attachment that includes a mulch plug and special mulching blades as well as installation instructions. 

Remember you will have to follow the 1/3rd rule. No more than 1/3 of the grass blade should be cut off at one time. This allows more efficient mulching and will promote the continued good health of the grass. If the desired cut height can't be achieved by cutting off 1/3, or there is clumping of the clippings, it may be required to cut higher; wait a day, then lower the mower and make a second pass. Mow at proper intervals approximately every 4 to 5 days.


This 42C mulching kit is compatible on the following models with 42C decks that have two blades.

LX255, LX266. LX277, LX279, LX280, LX288, GT225, GT235, GT245

LX266 install - great!
Works great for the LX266 JD rider! Easy to install. I removed the deck since my blades were stuck, but the whole job only took about 90 minutes including extensive deck cleaning. SGD had the best price on this by quite a bit!
