Long story short - last nite around 6:30. Unloaded both new Toro Z's at the building. Went to dump grass with trailer. Going to make a turn back to our building and waiting for traffic when BAMM & a jolt. Here a young male college student - admitting he was not paying attention re-ended me. His car went under the trailer, blew out the air bags on his car, smashed the hood, fender, windshield, car totaled. Trailer gate and gate assist were banged up pretty bad, the front of trailer got a little damage, the receiver on the truck total clasped ( body shop guys said they never seen one that bad where the whole thing gave way), dropped the bumper down, pushed my spare tire against the rear axle and exhaust, and tore out the mounting bolts in the frame. All in all, no one hurt - just metal. I was just thankful the two new toro Z's with 10 & 17 hours weren't on the trailer cuz I rarely strape them down in town, they would of flew into the back of the truck. Today was a reminder to all the guys - SAFETY first. No more this "it is only a block away" attitude. First accident for me ever and now time to pratice what I always preach!
