Today I got caught in the rain, I had just got started with my own lawn and said this shouldn't take long and no sooner I said that along came the rain. I want to tell everyone that other than the rain being cold, My Exmark Lazer Z Hp ran through that wet grass like butter. I thought it would bogg down but it just kept cutting like it was not even raining. I thought about what if this leaves grooves in the yard, but it did not leave a mark of any sort. I must have gotten lucky or something. I would have never thought about cutting in the rain, but I had to see what my machine would do and I am very satisfied with it. My wife ran me out back into the rain to take off my wet jeans and shirt. Well I just had to tell everyone about my day.
