Last couple of times I've mowed I've noticed my hands just covered with black spots after a while. My first thought was that the black paint or plastic or whatever from the steering wheel is rubbing off on my hands. I figured maybe it's because the weather is really heating up these last couple of times. But then it occurred to me: just about every time I go to get on the tractor the seat is covered in black dust that I have to brush off. Seems like it's worse lately I think maybe that while I'm letting the tractor cool down it's kicking soot up into the air and after I shut it off and leave it the soot settles on the tractor (including the seat and the steering wheel). Anybody else experience this?
