To me this time of year it doesn't really matter whether it is wet or dry. It's the spring and summer times where the grass is growing like crazy that makes it tough to get out early in the morning and fight the dew, however after a rain it seems not to be so bad as long as you're careful on the turf. The dew seems to keep everything packed together and the mowers will spit out clumps. I guess all mowers do this no matter what brand and the clumps can be removed with the leaf blower, but it's just irritating and time consuming that you have to do this. It just seems that with all the technology out there and all the testing these companies do that they would find a way to keep this from happening.
