I was doing some yard work yesterday and I noticed it was so dang hot that the grass was drooping . I had to lower the blade a bit just to get a good cut . I cut for about an hour and I started to get light headed and so I went to the truck and turned on the AC . I looked at the thermostat and it said 104. Hell , i was sitting in the shade. Its hot in N Al. I still haven't finished trimming. Too hot to play with it .
