1811 pto not working, no key start

Maybe you solinoid switch is the problem.
You could switch that out with a known good one.
You really should have a simple voltage tester for chasing electrical problems.

I had similar issues with my 1811 a couple of years ago. My tractor had bad connections at the pto switch. One of the spade connections on the pto switch was loose. I was able to resolder it. A couple of the harness connections at the pto were bad/rusty/corroded. I cleaned these up and tractor started. To start the 1811 the brake pedal must be depressed and the pto switch must be pulled down(pto off). There are 2 safety switches that affect/interrupt the operation of the pto, one on the seat and one at the hydrostat lever reverse direction. Here is a wiring schematic for the 1811, hope this helps.

A cheap voltmeter will really help you troubleshoot this machine. This is a fairly simple circuit to start the tractor. Set your volt meter to volts dc. Put the black volt meter lead on tractor ground or the - battery terminal and look for +12 volts dc using the red volt meter lead while trying to start the tractor with key switch turned to start. The black wire to the key start switch at terminal B supplies +12 vdc for starting. With key switch turned to start the red wire from the key switch at terminal S supplies +12vdc to the pto switch at terminal C. If the pto switch is turned off(pulled down) +12vdc passes through normally closed contacts(terminal C and D, both are red wires} at the pto switch and goes to the brake pedal switch. If the brake pedal is depressed, the switch contacts close and +12 vdc goes to the starter solenoid on another red wire .This wire is the small wire on the solenoid, +12vdc here should cause the contacts in the solenoid to close(if solenoid is grounded) and send voltage and high current to the starter on the heavy cable. I suspect since you are having problems starting tractor and using the pto switch that your problem is at the pto switch or pto connections. Mine were really corroded and a couple of them needed replaced but the culprit could be any of the switches/components or connections. Good Luck!

I'd say if you ended up bypassing the pto switch, then the pto switch may be bad. Mine is actually currently unhooked and jumpered because with it connected, it won't engage the starter on my 1872. I don't use mine for mowing though so I've just left it that way for now.
