You guys were such a great help with my last problem that the only place for more help is this site and forum!
Mowing down below in my ravine I disengaged the PTO to stop and move some wood. Went to engage the PTO and nothing happened. Tried this a few times and completey shut her down to check around to see if maybe the deck belt had broke, etc. Got back on to start her up and the classic drained battery sound and clicking, and after that nothing. So I took the battery out,covered her up for the evening and put the battery on a charger for the night. So my question is does this sound like just a weak or dead battery? If the battery is weak or on the verge of going dead will this cause the PTO to not engage?
Thanks for your replies and suggestions in advance!

Those magnetic clutches take some juice. It sounds like the charging circuit isn't working right or the battery / solenoid has a bad connection.

If it works OK in the morning, better do the usual checks for charging ( voltage before starting, after starting and at half throttle) you should see a full charge before starting, a little drop at idle following starting, and a steady rise to 13.5+ at half throttle.

Also check with the PTO engaged, if it's dropping with the PTO, you have a charging problem.

Those clutches do need the battery to work. If you belive the battery is on it's way out i would take it to a local auto store and let them test it. If the battery tests fine i would start looking at the charging system make sure everything is getting a good conection and working as it should.

I charged my battery on a trickle charger last night after taking it out. Took it over to my local Auto Zone and they checked it out and it had a reading of around 12.7. I have not put the battery back in yet but will do so tonight when I get back from work. Will keep you posted about what is happening with the system. Thanks again to all for responding to my post.

Did they not do a load test on the battery? One can show a good voltage, but drop off sharply when a load is applied. Once a good battery is placed in the tractor, use a volt meter to read the shut off voltage. Then crank the tractor & run at full rpm's & re-check the voltage. It should raise by at least one full volt, preferably more.

12.7 volt reading on a battery that's stood at rest for an hr or more indicates full charge in the battery, 12.6 to 12.7 is full charge, and should not drop at all the next day, battery at rest not used.
As said above next step is load test if that shows good battery is good.
Put it in the tractor and start the engine, take readings at idle and full throttle, should see a rise in voltage, if not charging circuit not working. (as said above)

Thanks for the reply and sorry for getting back so late. I put the battery back in my tractor after a few days of using my trickel charger on and off. She started right up but I have no means of tetsing the voltage....unless I go and buy a tester...which I probably should. Lets say after an hour of mowing I run into the same problem. Would this be an indication of a bad alternator and if so what's involved with changing it?
Thanks again for your help and suggestions.

Yes, you need a meter. Without some information, help will be more speculation than anything... It does sound as if you have a charging problem, but before you buy a bunch of parts you dont need, you should probably buy a MultiMeter.

Arguably the best on the market is a Fluke, but you aren't making a living with it, and there is no reason to go broke here. If you are in the States, I would order one from Harbor freight. I personally have several of these units

And keep one in my vehicles, junk drawer etc. If I smoke one, I am not out much and they are accurate enough for what I am doin 99% of the time.
