Dies when I start to move it. I bought my mower almost a year ago and it is wonderful, but this year I have have had this problem twice now. Mowing my yard just fine until the battery dies, put another battery in so I can continue and it starts just fine but when I start to move it to mow it dies. I have 2 batteries and it does this with either one of them. I took it to my local Home Depot and the associate & I put on the ground so I could show him what it does and it worked fine. Here I am again with the same problem about a month later. Does anyone have any suggestions on what could be the problem?
