Not A friend had a chance to try out a new self propelled sprayer this past week, The joystick handle for the hydro first gave him problems as he was in some soft ground and instead of pulling the machine thru it just gave up and stopped. It is the kind of ground you have to keep rolling thru because if you stop you are stuck. So they got it pulled out not to bad. 2 days later he is spraying around a water way and it gives up on him again and stuck, so they pull it out but as the tractor stops because the machine is out he pulls back on the hydro in the sprayer and it doesn't stop, he has to go all the way to reverse and then it starts backing up but not before getting close enough to the tractor to break the back window. Luckily that was the only damage. New joystick handle is suppose to fix it. His 5 year old sprayer is sitting in the shop waiting for a new little black box.
