Hello everyone - I have a 1972 Ford 5000. Bush hogged with it yesterday and then it started acting up a bit. It has Independent PTO - and the PTO has very little power. When engaged, it will not spin the bush hog very fast and when I lower it to cut, it will just bog down and stop. Tractor is revved up, but the PTO will not spin. Friend seems to think it is the main clutch - but I think it may be a bad PTO clutch. Can we replace the PTO clutch without breaking the tractor apart? I have looked online fiercely to see exactly where the PTO clutch is - but all the reference manuals are not definitive. Is there a shop manual available online? Or does someone know. Can the clutch be tested? The clutch will stop the bush hog from turning, but does not have power once it is engaged. I pulled the rear inspection plate off the back between the wheels that is located just above the PTO - the plate holds a bearing in place of course. I thought that was it, but couldn't tell. Help if you can - I don't want to break it apart and change the clutch and that is not the correct thing.
