check dual brake pedal switch. Mine checked ok with ohm meter , but when i jumpered across,, it solved my issues !!! . If the engine dies when you turn on pto then it is definately a safety switch. !!! there are 4 in the circuit !!
Aren't there 4 wires on the brake safety? Which ones did you jumper? I've been having this same issue for a year and I'd love to get it fixed. Thanks!
