    I have a toro proline 52 that will run fine, and drive fine. However when you eengage the blades the wires leading to the clutch melt and eventually short out and the blades quit. I have replaced the wire with a higher gauge wire and experienced the same problem. Any ideas? Is the clutch just shot? Any help you guys could give would be massively appreciated. I am looking to start a lawn service company in the near future and really could use some chips to fall my way. Thanks in advance.

    Unplug the clutch. Get an ohm meter. Check the ohms from wire to wire. Now check the ohms from each wire to the metal frame of the clutch.

    Now some newer PTO clutch systems have a blocking diode in the clutch wiring and if you get the wires hooked up back-wards you will have problems.

    Wire to wire you should get from 2 to 5 ohms. This varies from clutch to clutch and from meter to meter.
    From wire to frame you should get open. Do your test and post your reading here.

    Give model and serial of the Toro and any numbers that may be on the clutch itself.
