PTO light

[daTeacha]

While working with moving rocky dirt in a rough area, my PTO light came on even though neither PTO was engaged. The light wouldn't shut off when I engaged and disengaged the PTOs, and didn't bother anything, so I kept working.

A while later, I shut down the tractor, coincidentally parked in a place that effectively blocked both cars in the garage. When I went to restart it, the PTO light was on and the starter would not engage. Crawling around under the tractor revealed a disconnected wire. Plugging it back in shut the light off and enabled a normal start.

I'm just tossing this out there in case it happens to someone else. The wires and such are pretty well protected by the layout of CNH machines, but they can still get snagged now and then. If things are working and then suddenly aren't, check for a loose wire somewhere.

So true..

This thread should be a do not delete.

The disconnected wires under the machine have been talked about many times. Why NH felt the need to put that sort of arangement that will disable the tractor on a qd wire plug, under the tractor where it is certain to find brush and other debri is beyond reasoning. if the NH engineer that designed that 'flaw' had to fly out and personally fix every instance of that causing a problem, my guess is his very next design would put that 'disable the tractor' wire in a much different place.

ironically.. it may not even be the engineers fault.. but rather a bean counter that decided that NH could save 1/4 a cent on every tractor by running that wire there. in that case.. the $!&*%^& bean counter should have to crawl under the tractor laying out inthe brush or pasture or whatever and have to fix that connector every time it snags... than see how much it was worth...

My tractor does not even have the pto light as part of safety. All I got is a lowly Neutral safety switch and the wires are well protected relatively speaking. Can you guys do your own " after market engineering" by putting the wires in some sort of metal conduit and making some bracket out of metal junk pile to secure it to the tractor ? I don't think it'll be too tough to tidy thing up under the tractor to avoid future problems. my 2 cents.

AND if you plug that wire in backwards, the tractor won't start unless the PTO is engaged. Ask me how I found that out.....

I know you could jump the connection easily enough, but this is the first time in 200 + hours of running around in the woods that I've had this happen. I didn't realize it was a common happening. I just figured those who are fairly new here would like to know about it in case they have it happen.

Compared to some of the other brands and colors I looked at while shopping, the CNH set up is pretty well protected underneath. At least there isn't a glass fuel filter bowl hanging lower than everything else on the tractor like I saw on a couple others, or hydraulic lines low where they could snag a branch, root, or rock and burst. Breaking a fuel filter would be seriously annoying since it would not only shut you down, but you'd need to get a spare bowl or other part, install it, and then bleed the system before you could go anywhere. A blown hydro line -- well, let's just say I'd rather not think about that happening anywhere, much less out and away from the shop.

Well, I reckon I'm asking.. how come?

The switch is a spring loaded normally open dry contact. Once it is closed by pushing the clutch pedal the staring circuit is made and you can proceed with turning the engine over. I don't think polarity has anything to do with it.. please explain

For sure.

Well when it happened to me, and I found the plug un plugged, it was kind of dark, so I figured the plug was keyed and you couldn't get it wrong, so I plugged it back in. When the tractor wouldn't start I noticed the PTO light was on, but the PTO lever was not engaged. I engaged the PTO lever and the light went off and the tractor started. After getting a flash light to check things over better, I noticed that I had the plug in backwards! A quick fix of this and I was back in operation. This was on my TT50-A tractor.

Mine wasn't the plug, just a wire connector. One wire was disconnected. The plugs were fine.
