I have a new BX2380. I've only put 3 hours on it since taking delivery. All the time has been spent blowing snow. I've noticed if I raise the 50" blower to its full height there is a terrible grinding sound. I'm sure this is caused by something coming in contact with the PTO shaft.The blower was installed by the dealer prior to delivery. I contacted the dealer and was told this is how the system is designed and there is no fix. This is very hard to believe. I can't imagine Kubota putting this system in the field with such a design defect. Is anyone else experiencing this problem and/or is there a fix for it?
