2009 TYM T503 PTO quit working

Was working fine then it just quit turning. No loud noises, nothing blew apart... just quit turning. Noticed the little PTO light is not lit on the instrument cluster now either. Any input is appreciated.

JFahey, did you ever figure this one out? Thanks...

Yep. It was the controller assembly monitor. Haven稚 had a problem since I changed it.

Thank you for the timely reply "J".

I do not have the maintenance/service manual for the T503 and I am curious what led you to the "controller assembly"? What and where is it? Is it the PTO red switch or is it the PTO mode selector switch below the red switch?

Apologize for the blast of questions. Not that I am experiencing a similar problem but your post was of interest.

My 503 has been a great machine, roughly 550 hours now. I had my first problem recently, could not engage/disengage 4-wheel drive. Ended up being the front drive shaft spline. During discussions with my dealer at that time I mentioned it was always tough to engage and disengage. Always took a lot of effort on the handle. He told me to do one of two things, either use the FEL to lift the front of the tractor (which then reduces engagement stress/effort, or, put the beast in reverse and ever so slightly let the clutch out, then shift into 4x4. After that repair I used the FEL method, it took two fingers to shift into/out of 4x4. Thought you might be interested in case you have not heard of the "technique".

Thanks again. Be safe and be well.

I spent a lot of time trying figure out what was going on. It would work one day then not the next. Something was making and breaking contact. I found the bad connection by pressing on and bending the controller. It would make it work then it would quit when I let go of it. It is a black box mounted to the firewall under the dashboard. Cost about 300 bucks and it has been perfect since I changed it. It looks different than the original. Dealer said it is a new and improved version so they must have had some problems with them. As for the 4wd, I have not had any issues. I make sure I知 in neutral and I have the front wheels as straight as possible. Thanks for the heads up on that though. Overall I am very happy with the tractor. Always starts even when it is well below 0 Fahrenheit and pushes snow like a champ.
