My John Deere LA130 runs fine until you pull the pto switch out then it stalls the engine. Does anyone know what the problem is and how to fix it?

MIGHT find some answers in here .....

I'm going to move this thread over to our John Deere section.

First thing to check, is it running on both cylinders?

The mower runs very smoothly when the blades are not engaged. Also I just discovered that I can pull the PTO switch out just a little and the blades will engage and the engine will run smoothly, however, If I fully engage the switch the engine stalls unless I push the switch in to disconnect the PTO. Maybe you or someone can come up with some idea as to the problem. PLEASE.

I think I would take the PTO belt loose and see if the cutting deck spindles rotate freely, sounds like something is stopping rotation of the PTO or the spindles, anything blocking the blades or a spindle pulley ..??? does the mower run good at all times without engaging the PTO ???

I've tried that and all three blades turn freely. the mower runs fine without the PTO engaged. As a matter of fact I can move the PTO switch out just a little and the blades will turn normally as well as the engine running fine, but if I move the switch off that spot the engine will stall or the blades will quit.

My bet then is to replace the PTO switch. It is probably shorting out when fully engaged. Here’s a time when I would recommend taking it to a dealer and ask them to replace the switch. If that is not the problem, they can take the new one back out and put yours back in. If you purchase a switch, put it in yourself and it is not the problem, being an electrical component, it is probably NOT returnable.

I have replaced the PTO switch and the rotary key switch also the RIO switch. I guess the new PTO switch could be bad, but, maybe I should go ahead and take it to dealer for service. I just hate to spend the money and time.. Oh well. Thanks for the suggestions and if you think of anything else just go ahead and post. Thanks again.

Spend $ 10 and buy an in line spark tester
Hook it up, get some one to sit in the seat and with the engine running get them to engage the PTO switch.
If the spark tester stops flashing then you either have a wiring problem or a faulty PTO switch.

The manual your were directed to download has very detailed instructions how to test the PTO switch

It worked, the mower is operating normally and my wife is so happy because now she can cut grass. Thank you very much to all who replied to this post.

What worked?
How do you fix it?

Some one may have the same problem and read this thread for help.

More importantly, how did you get your wife to mow with it?

Be careful what you wish for Tom.
There are a lot of widows in the service run .
The most common comment I get from them is
" If I new mowing was this much fun before he died, I would have been mowing & he would have been dusting" :laughing:
