I am just wanting to warn all of you with ATV's to be careful. Things can happen in a blink of a eye. This evening I was spraying some hedge apple and honey locust bushes back on my farm a mile from no one . I had a full 200 lb tank of spray strapped on the back of my Honda 450 four wheeler and a large battery tied on the front rack. My ATV is old and the brakes are not very good. I was spraying on a hillside that was not real steep . I had my hands full trying to guide my ATV and spray . All of the sudden I lost control for the slightest bit and rolled my ATV off a cow path . When I finally came to rest the ATV had me pined down on my right leg between the back tire and my foot was twisted out toward the back . The ATV was still running and finally died. I was facing the bottom of the ATV. I could not move , just sit up . I tried to pull the ATV over a little so I could pull my leg out but with a full 200 pounds of spray strapped on it, I could on barely budge the ATV. I tried to dig the soil out from under my leg but broke my knife . Gas was pouring out of the carb and all over my leg so reached under and turned the shutoff on the gas tank. I finally got some rocks and placed them on the upper side of the back tire and every time I rocked the ATV the rocks would roll under the tire . The tank leaked out the spray solution making things lighter. Finally after 2 + hours I finally got my leg from between the back tire and out from under the fender but still could not get free .It was getting pretty dark. I got to looking and I had the electric cord that run from the battery to the pump wrapped around my leg . My leg was numb and I could not feel nothing. I took what was left of my knife and finally cut that cord . It felt so damn goo when I finally got free. I was like a trapped rat . If that ATV had rolled over a little more I would have been all the way underneath it. I thought I would be there for hours as I am always away from home late and my wife would not get worried until 12 or 1 PM I had no cell phone and my son was in Louisville with his son and wife at a booth down at the Fair. I am really lucky that things turned out ok . My leg is killing me and I hurt all over . My back feel like someone used me for a punching bag. Just be careful is all I can say.
