Lawn Tractor - Mower Deck Maintenance

Any tips/tricks for minimizing the grass clumps and/or dirt build up? I know overtime regardless of any product you will still need to scrape or power wash. I read things from getting a powder coat, graphite sprays to using PAM cooking spray and there were mixed results with all types.

Yeah. I try to only mow when it's dry, but where I live, it's not always possible (permanent shade, pretty wet summer). That's why this year has been so bad. So I bought some Teflon spray at the local hardware store and will see how that goes. It was only $4 for the bottle. The mower does come with a deck wash port, but that is next to useless.
