I hear you. The grass in Georgia will stay wet with dew until noon or a little later. I’ve been running OEM Gravely/Ariens blades on my Pro Turn 160. They do a decent job however, I can get some buildup too. Sometimes clumps will fall out over the yard and I will have to go over it. The first thing to do is not let your grass go more than seven days before mowing. I try to mow every six days. That’s been pretty hard to follow with the rain we’ve been having. Make sure you deck is leveled and pitched according to the operators manual. I like about 1/4” pitch in the front. When it’s too bad, I will shut it down, raise the deck to transport height, and hose out from under the deck. DO NOT do that with the blades turning. Then continue mowing.
I wanted to try something different. I have used Oregon Gator G3 blades on my formally owned Toros and was not happy with the results. I decided to try the Oregon Gator G6 on my Gravely. I put them on Tuesday and mowed. Boy, was I surprised. The results were fantastic. I didn’t have to recut and I didn’t have clumps falling out from the deck. I may have found my new blades. Time will tell. They are pricey.
Here are the blades. I got mine off Amazon. The seller was PAE Distribution.
