    Default Grass build up under mower deck

    Does anybody have an idea on how to keep (or at least slow the process down) grass from building up under the mower deck? Thanks

    Derek, I clean mine every time I sharpen blades(about 30 hours). Do you have to clean more often ?

    The old man down the road says spray it with silicon spray. I have also heard PAM cooking spray works to keep the build up down.

    I suppose different things work for different people, but I tried silicone spray, Pam, and repainting the underside with what was supposed to be a paint that the grass wouldn't stick to. None worked very well. I still can't say I've found anything that was perfect, but the best thing I've found is to spray on a mixture of 75% diesel and 25% motor oil before mowing.

    Bird,

    That's definitely different...

    How do you clean up the deck... strike a match?

    It didn't help the buildup much, but my dad fitted a hose fitting to the top of the mower deck. After mowing, he would attach the garden hose, and rev up the mower. The water would hit all the same places as the grass, and it all came out the chute. Wasn't perfect, but it was cheap, simple, and quick.

    I like Bird's suggestion too. Never heard of that, but would be fearful of any sparks [img]/w3tcompact/icons/shocked.gif[/img] in the near vicinity...

    Well, I don't smoke while I'm spraying it.[img]/w3tcompact/icons/laugh.gif[/img] And I use a sprayer that puts out a very fine mist, so a gallon of that mixture lasted me 3 years. Sometimes when I finish mowing, I blow any grass off with the air hose, and sometimes I wash it off with the garden hose, and sometimes I don't need to do anything to it.

    Do you only mow dry grass? I have heard that wet grass will stick to your mower deck besides loading the engine more than dry grass.

    Now, a _completely_ serious question...

    Why do you guys clean out under your mower decks? I have seen decks worn out from mowing so much grass that they wore away from the constant sanding action, but I haven't ever seen one rust away. ?????

    I have never timed it. I seems like maybe 6 to 8 hrs for the build up to get to the point where it effects the cut quality. I sharpen my blades twice a season. I'm very careful of not hitting rocks. This is on my JD318.

    For some reason the mixture of diesel and motor oil mixture sounds familiar. Any special weight of oil?
