Tips for preventing trimmings buildup underneath mower deck?

The grass is very wet this year and I am having to stop mowing often to clear the trimmings adhering to the underside of the mower deck because the engine begins to labor. Is there any way to minimize this?

Cut it more often, raise your blade height, and don't cut wet grass.

And don't do like my old neighbor. He would putt around with the engine barely above idle. He said he didn't want to go fast and didn't want to stress the transmission by upping the rpm and letting the hydrostatic drive do what it was designed to do. So he'd fully engage the drive and adjust speed with the throttle. That meant his blades were not turning at the optimal speed.

Good point. My Kubota ZD21 stipulates it works best WAO, so don't skimp on power.

.... and be sure to clean the underside of the deck after you are done mowing. Dried clumps of grass under the deck will reduce the effectiveness of the mower and accelerate rust/rot.

I may not be the most orthodox environmentalist; but every time I change the engine oil, I also remove the Deck, clean it, dry it, and then slosh on a coating of the used crank case oil around on the underside to impede rust, and to make it a bit more resistant to accumulating a build-up of grass clippings.

If I have the time and feeling froggy, I'll repaint the underside of the deck on my push mower when I change the oil and sharpen the blade. I would have thought the grass would stick to the used engine oil.

After cleaning I spray it with WD-40, grass doesn't seem to stick near as much and easier to get off later.

Mo-deck spray works. Best to mow dry grass but some grass holds a lot of water in it's cell structure like winter rye and some fescues and it's wet even when it's dry. If the klift portion of your blade is worn down, it will cause more sticking. If the RPM is too low, or the chute is not open, it will also cause poor ejection of clippings.

Sometimes I sit it on concrete and run water under the mower with rpms up. The mower sucks the water up off the concrete and washes the deck underside. Works pretty good right after a mowing.
