Cub Cadet 2185 starts and runs as long as I keep starter in the "start" position. Will also keep running if I spray engine start fluid in carb while switch is in "run" position. Fuel pump is working, gas tank flushed, using new gas. Something going on in carb? PTO switch? Starter switch?

SOURCE: A short in the pto wiring perhaps?

Form what you are desribing you have a direct short, probaly in the wiring going to pto. I t has rubbed somewhere and is causing your short. Unplug the wires at connector close to your pto clutch and try it again and see if fuse stuill blows after you unhook it.

If the fuse still blows it is in the wiring going back up to thje switch. If the fuse does not blow after unhooking wiring connector the problem is in the clutch.

A defective fuel shutoff solenoid under the carb bowl or a carb that needs cleaning/repaired.

SOURCE: Cub Cadet LT1042 PTO won't disengage

If its an electric PTO then the switch on the dash is bad, Its a lever type ungagement then the little break shoes that rub on the blade spindles are either worn out or mis adjusted.If it started when you changed the blade drive belt its possibly the wrong belt??

Sounds more like a PTO clutch failure, rather than the switch. The clutch is mounted on the engine shaft, between the hydrostatic drive pulley (nearest the chassis) and the mower deck belt pulley (farther from the chassis).
Since it's an expensive part, make sure the problem isn't in the switch or wiring first. You could do that by probing the wires to the PTO clutch with an automotive test light - they are inexpensive and handy. Clip the ground wire of the test light to the chassis, and probe the hot wire to the clutch (it's the one that doesn't connect to ground) when the engine is running and the PTO switch is engaged. Obviously a helper has to be in the seat, and you should be careful doing this. If the light glows brightly, and the clutch doesn't engage, you definitely have a bad clutch. Good luck! Please rate my answer if helpful, thanks.
