what is the full model number of the mower? Some mowers us a relay between the pto switch and the electric clutch. Have you checked the electric clutch , with two wires direct from battery to be sure the ,magnet will close?
Is there a relay? If not, you have wiring probelm between switch and clutch. Do you have 12 volts to the switch?
I see question is still open, did you find model number and check for relay?
