looks similar to wha ti had to deal with a few weeks ago. there is one spot in my yard hta ti just cut Saturday for the first time since early March due to water standing 6 inches deep there. at least the grass/weeds were thinned out considerably.
I have a spot like that on one of my trails. I used to mow it wet but now I just wait. It usually dries up by early June to not make a big mess. The 748 goes through the high grass with no trouble. I make one pass with the mower up and then do it again at 3". It dries out quicker once it is mowed. Once it is dry then I use the L3400.
