How do you unclog your mower deck?

I found a technique to clear a clogged deck that seems to work well.

Once you see, hear, feel the deck is clogging, proceed to a "dumping ground" with the mower still running at operating speeds.

At the same time, turn off the mower and drop the throttle (with the objective of getting the blades to stop as fast as possible). Depending on your mower, an alternative technique is to kick-on one of the safety switches by lifting yourself off the seat or something.

When I do this, all the caked on stuff falls off the deck. Any blades that have lift are pushing it up there and if you stop the blades quickly, the built-up grass falls off the deck under its own weight. I mentioned "dumping ground" since there's now going to be several inches of caked up wet grass sitting there... Not something I want in the middle of the yard.

I found that Fluid Film also does a fantastic job of keeping grass from sticking to the inside of the deck so I apply that after every through cleaning of the underside of the deck.

I have had guys tell me they used Pam (that spray stuff) but I dont think I believe them. I cant remember having it clump up so much bouncing the deck on the driveway or something doesnt clear it. I think you are suppose to throttle down before you shut down the mower anyway, I always have but I am not sure why.

Yea, I'm addicted to that stuff (Fluid Film) now... I have gallon jugs as well as spray bottles. I hit all the power equipment, garage door parts, hinges, water spigots, the ends of the garden hoses, trailer couplers, lawn rollers, aerators, blades, rototillers and other implements that are done for the season...

Basically, if it moves and/or could rust, it gets a coat.

I used something different a long time ago. It was a spray on that I could only get online. It worked some but not worth the money I paid for it.

I just raise the deck so the grass can get out...

Otherwise, I don't mow in the rain...
