My JD 270 has the brake locks stuck on and they won't release. I have wired around the seatbelt as that gave me problems last yr due to oxidation (very humid in Kauai where the machine is) I have checked the wires going to the solenoid adjacent to the hyd filter and it has power going to it when I push the park brake release switch. It is almost impossible to work on the machine when the boom is down as there is no access to the engine compartment. I need to find a brake release that will allow me to raise the boom to see what is going on. I probably have a bad solenoid but have no way to check it and since they are pricy I don't want to just by one on a guess. Does anyone have any ideas or suggestions?
