It's hard to give you advise when you have another full time job..given that you only have certain days you can work. We can say wait it out etc. But in your case can you really? It might be best to deal with the clumps and tire skids . One of the guys made a good point as far as " what do you use" in my case .. I've tried mowing when it's really wet and my ztr just clogs and spits **** everywhere , and my belt driven walk behind is worthless!! So I take the rain days and maintenance mowers, catch up with customer calls, estimates and paperwork.
