Thanks for the feedback. The mulch kit is on its way.The mulching kit on my Deere lawn tractor has pretty much eliminated raking leaves. It does an amazing job.
As the Fall grass starts growing again after the hot dormant Summer ( I'm in Connecticut), the mulching kit pulverizes the long grass and leaves together. Obviously key for leaves to be dry so I'll let them fall and I'll mulch them up before the next rain. Around trees, rocks, and walls I'll carry a blower which I aim in front of the tractor to blow the leaves into the path of the mower- elevating laziness to new heights.
Mowing over piles of dry leaves in the driveway a few times reduces them to leaf dust- literally, which I then blow into the yard.
Happy mulching. : )
Don't know if this will link directly to the picture of the deck inserts for a 54" deck which might answer your question: https://shop.deere.com/medias/BM208...RlM2RiYTYxN2FkYzM3Yzc1YTFiYmNkYjc1NTFlMWM3NWMIs it partially baffled, or fully baffled (meaning a dedicated mulching deck)? Sounds like yours may be a dedicated mulching deck with a sealed off chute. In which case, that's what I'm saying about a higher lift blade not working out for it. Even if the deck doesn't get caked up enough for you to have to scrape it, the high lift blade will keep the clippings up in each bay for too long as you're mowing, clogging it up which hurts the cut quality.
On a pass-thru deck with partial baffles like my Bradley, the idea is that grass get mulched "good enough", and then gets side discharged. It's a compromise basically. If I block the chute, it soon becomes a hot mess under there unless I mow at a higher setting than I like to (3.5" in the summer). I only block the chute during leaf season.
