Hi looking for an idea to start looking. I have a x300r and I just replaced the belts and I am testing it out before i reassemble the rear bag assy. Mower starts and drives fine.  The problem starts when I try to engage the pto.  If the brake is engaged the engine stays running. If I let the brake off and press the bag install switch the engine shuts off.  The position of the pto switch does not matter.  The engine dies as if I turned the key off.  It is not bogging down like the belts are two tight or a bad bearing. I have engaged the pto like this before while the bag is not installed while clearing a clog.
Thanks in advance for any help.
