M5030SUMDT Fusible Link/Live PTO

[Misfit]

I own a 1994 M5030SUMDT. When I first bought it 5 years ago, the PTO disengaged when I pressed in on the clutch. Now, it doesn't do anything to the PTO when I press in on the clutch. A couple of years ago the fusible link on my tractor came loose and eventually I removed it altogether. I was in the middle of a huge bush hogging project, so I was just trying to get it fixed and get going again. When I removed the link, nothing immediately happened (tractor started, lights/panel worked, etc.), so I went back to cutting and didn't think about the PTO not disengaging when I pressed the clutch...or if I did I ignored it and kept going trying to finish. Well, I didn't fool with fixing the fusible link because, honestly, I forgot about it. My questions are: 1. Does the fusible link actually control the live PTO (I hope I'm using this term correctly)? 2. How do I rewire the fusible link? 3. If the fusible link doesn't control the live PTO, how do I fix my tractor such that the PTO again disengages when I press all the way in on the clutch? Thanks for any help you guys can offer.

No the fusible link has nothing to do with the PTO.
The PTO clutch is mechanical not electrical.

Clutch might need adjustment, Get the WSM for the tractor and it will explain how to adjust the 2 stage clutch (Not a simple operation without the WSM).

Get a new fusible link of the right size and crimp in a new link.

Thanks a ton, Wolfman. I had no clue what the fusible link controlled. Any ideas? I ordered the service manual yesterday. I'll give it a go as soon as it arrives and try to add to this post. Thanks again.

Lets be certain we are all talking about the same thing when we say "Fusible Link."

If it is blown then you would have no electrical power as the "Fusible link" is like the main fuse for the tractor electrical system and it will feed everything except the high current starter cable.

Could you post a picture of what you are calling a Fusible link?

I'm hardly knowledge about electrical circuits, so I may be muddying up the water. This is what i'm calling a fusible link. It was wired into the starter or something right around the starter...I've never lost power to the tractor.

I now have the service manual for my 5030SUMDT, but I can't find where it shows where and how the fusible link should be rewired. Anyone have advice on where it should be wired in? Again, thanks for all of the assistance.

Does your WSM have a wiring schematic in it?

 

[Misfit]

It does have some wiring diagrams/schematics, but I'm not certain how to interpret it. From the diagram, it looks like the fusible link is wired into the red (hot?) wire on the starter and to the red coming from either the alternator or starter relay. Attached is a picture of the diagram.

The images you are posting are too small for me to make any meaningful comments.
My method of posting pictures is to upload them to a hosting site and then paste the link they provide into my post.
I use www.tinypic.com but there are others.
Here below is an example:

It is possible what you are posting is a slow blow fuse which is somewhat like a fusible link.

Here goes with an attempt at a bigger picture. Not sure how much better it is.

 

[Dave_eng]

Your image was no better but I enlarged it enough to see that there is s special type of fusible link that looks like the one your posted a picture of earlier.
I have marked it with a red arrow.

It appears to be serving critical circuits so should be replaced.

I would need a better picture of the fusible link you posted to determine if the loop of wire is the fusible link and there is a plug in connection to install it into the circuit.

Hope this is clear.

Evidently, I suck at pictures. I'll take a picture of the actual fusible link that I have this evening. Thanks so much for the help.

If I didn't mention earlier, the old fusible link isn't even there anymore, yet the tractor still runs and seems to function normally. My father-in-law and I tried to get it hooked back up when it started to come loose, but it was past the point of saving. We just cut it and went on about our business because nothing seemed to be affected. Its been this way for a couple of years, and I'm just now getting around to wiring it back in like it should be. I don't want to run the risk of frying something when I hook it back up and power it up, thus I'm seeking assistance in doing in properly.

 

[Dave_eng]

How about posting a picture of the actual wiring around the starter.
Perhaps you bypassed the link years ago otherwise I dont know how things could operate.

I think that the connector was cut out of the wiring harness when you and your father-in-law removed what ever you took out. You may have to repair the tractor side or hard wire the fusible link in place
