    Need help please:

    I have had the Toro Z5000 for about four years. The other day I went to mow and it cranked right up just like always. When I got out in the yard, I thought I smelled something burning. I thought either a belt or maybe it was low on oil. I rushed back to the garage and shut it off. I removed old grass to check belts and sprayed water to removed a bunch of old matted grass. I even added a little oil since i couldn't tell if it was low or not since the engine was warm.

    Now, when you turn ignition, starter just clicks. I have checked PTO switch, checked both fuses, bench tested solenoid, bench tested main kill switch, both arm lever switches, and had battery checked just in case. I replaced the solenoid just to be sure. Also, the battery is about two months old.

    Just in case it matters, the voltage drops from 12 to 7, when the ignition switch is tuned over and you hear the click.

    I took the starter off of the mower and bench tested it. It engages in and out and spins like i think it should when power is applied direct. Put it back on the mower and it never turns over, just clicks. It seems to stay engaged and never disengages.

    There is a PTO clutch/brake switch on the bottom of the shaft, underneath the engine. I disconnected and cleaned with air compressor as best that I could. I don't know if that did anything, but I'm not sure what else to do with it.

    Does anyone have any ideas?

    The above shows a low battery voltage (should be 12.5) or bad battery no matter how old it is, Charge the battery and try it again. If still no go and you still drop to 7 volts replace the battery.

    Once you get it running on a good battery check the charging system output across the battery, It should be 13 to 14.5 volts at higher RPM's depending on charge state of the battery.

    BTW, You eliminated a starter issue by bench testing......

    I've got people telling me that rust on the flywheel might be the problem. Does that sound possible?

    What about ground problems?

    [​IMG] ........ Nope !

    You can check the negative battery cable where it bolts to the frame/engine, But I still feel your issue is the battery and or possible charging system.

    hey thanks for offering your help. I cleaned the flywheel and magnetic contacts. still nothing. I ran a ground wire from neg battery terminal to a frame bolt. That didn't do any good either.

    I tried jumping with the car as well. Wouldn't that take care of a bad battery problem?

    Well I just jumped two top post on solenoid with switch on and off. Got sparks and starter just clicks. I read somewhere to do that. Does that mean anything?

    Sounds like you have a seized engine.
