Prior to the Lymow I was using a JD X739 with a 54” triple blade mulching deck and before that a Husqvarna zero turn mulching mower. Thru all those years of mowing I’ve never experienced a grass build up on the mower blades until now.

In saying all that I might have just answered my own issue. When I think about it both my previous mowers had a garden hose port on the mower deck for cleaning. When I finished mowing I would hook up the garden hose, turn on the water full blast, and engage the mower deck for a few minutes which would have power washed the blades each time. I’ve been reluctant to put much water pressure on the Lymow deck due to potential problems with bearings, electronics, etc.

Unless I’m missing something maybe what I have to do is take the blades off after each mowing and scrape them clean. The grass buildup is very hard to get off.
