Please use caution when working under your machine if you have a helper moving levers up top. I say this because a man was run over by his own machine around here a while back because he was in a rush to "fix" something under the tractor. Apparently, he was trying to get some debris out of the mower deck and he had a helper sitting on the tractor. The helper accidentally moved a lever while the tractor was running and it ran over the guy laying behind the tractor. He is no longer with us today.
