yes this is being posted to help my dad he has a yale type L9. the model number he gave was glp050tenuae080 serial number n511159. he was driving it and it stopped all of a sudden. the lift part still goes up and down left and right. it will not move its not the brakes due the fact if its on a hill it will drift backwards. he says he may move forward 2 or 3 inches that's it. it has all the fluids propane. so any help would be greatly apprecitated
