I just found this site. I have an older troy bilt 16 hydro. I can't find the serial number or model number and lost all its paperwork when my house burned three years ago. We used to have a snow blower attachment and tiller attachment that went with it but they were stored next to the house:(, It is an older tractor and needs some work. Right now it starts ok but will not go forward or back ward. I am in no way a mechanic and have no way ot load the little rascal to get it to a mechanic. Does any one have an idea why it would suddenly stop going into gear?
