Need some quick 1811 PTO help

alright here's the situation. I finished mowing with my 1811 last weekend. Parked in the driveway and gave it a wash down. Removed the tunnel cover and sprayed off the transmission. I made sure to take care and not get water on the dash or down inside. Fast forward and now my PTO will turn on but wont stay on. I have tried switch from a verified working machine along with another battery. I have the seat safety switch bypassed and am now out of ideas. Any thoughts would be appreciated!

The "hold in" relay isn't holding. Either it went bad, or there is a safety switch that isn't making contact. The 1811 should have a reverse safety switch and a seat safety switch. Make for sure both are making contact.

A quick check is to run a jumper from the battery or any hot spot on the engine with 12 v and connect it to the wire of the PTO. If it locks on and will not release then it is somewhere else and not the magnetic clutch. I do not know of any holding relay or solenoid. The magnet is either on or off if it has 12volts applied to it. I suppose there is one in the PTO switch but usually if that were the case then holding the switch to the engage position should keep it engaged so that would tell you that the switch was bad. If it is good with a direct hook up work your way back via the safety switches until you get the one that is causing the problem.

Thanks guys! Turns out it was (mostly, long story) the reverse relay. Ended up "removing it from the equation" to resolve the issue. On a side note, I now need a new key switch as the old one was pretty bad. So, off to the parts store tomorrow and back in business by noon!

The parts book calls it a "reverse relay". But, it's really a hold in relay. It's one the dash tower, under the side panel, left had side. OEM is silver in color.

I have always wondered what that silver box was! I also did away with the reverse relay since I use reverse so many times while mowing that it would be absurd to have the PTO cutout every time. JD has a momentary push button that keeps the deck running on their newer mowers but it is still silly.

I agree. If you don't know enough not to back over something while mowing, then you don't need to be operating a lawn mower.

Agreed. And where is the reverse push button on the JD, on the dash? How are "they" going to remember where the button is without looking if they can't remember to turn their head before backing up? So now the person who is prone to not looking while backing has to look forward at the dash to find the button.....and they expect that to help them look behind them??
