Help Lx277 pto/deck problems.

[DIESEL-FUMES]

Greetings..I will keep this as short as possible. which is pretty much impossible for me..
Anyways, I have a JD LX 277 that I bought new many years ago. I always have kept up on maintenance on it and other repairs. But this time it was due for the make over..
I rebuilt the carb, adj lifters and etc. Plus. I did a complete rebuild of the deck. Filled in the thin rusted metal and installed all new spindles, pulleys, belts, idler arm, serviced the transaxle. I also replaced the pto as it was becoming loud and wouldn't always engage. The problem I now have. after I hooked the deck back on and the new deck drive belt it really started to squeal and make all kinds of noises when I engaged the pto. I had to order the pto and I did this with the original pto still installed. So, I just chalked it up to the old pto. Which, after I replaced it. I found the bearings where defenitily worn out. Not seized but not smooth.. Once I received the new pto and installed it. I double and triple checked everything before engaging it. Well, it did the same thing. Only not nearly as bad.. the deck pulleys and system does move freely. Not hard to rotate by pulling the drive belt. It is harder than before but only because of the new belts. As the old ones where original and where about ready to break. So finally here comes the question. Eventhough I am a somewhat experienced grease monkey. I am at lose at what I am missing. The pto clicks in just fine with the belt not on.. I dont see anywhere on the old pto and the new pto where you can adjust it with the feeler gage. Atleast I dont see any adjustment areas..
The deck runs freely. With the new pto. It's not as loud. However, it by far to loud and the blades seem to never get up to speed. When they do they will slow down.. the belt first seemed tight when I installed it. However, now it has slack. I dont have a repair manual for this tractor to find out what kind of slack. One thing that I did notice after I leveled the deck it seemed like the belt was slipping a little more.
So I would appreciate any help or
Ideas.

something I might be missing

The slack on the deck drive belt..

You are saying that the primary deck belt has slack- correct? Are the mounting holes at the rear draft arms horribly worn? It's one of those follow the chain kind of things. If the deck positioning is proper, the belts and spindles OEM, one would think that your tension spring is fatigued.

Does this location in the circled area have interference with the deck mounting?

I think that Tom P is correct, the main drive belt or the belt on the deck are not tight enough.

Can you more closely describe your squealing? I'm asking for a metal on metal, which can squeal but usually has a grinding tone to it, or a rubber meets steel squeal, which may go away with a little run time, but be back with a cool off period, or come and go due to load conditions.

Are your new spindles or pulleys the greaseable type?

Thanks everyone. Sorry I didnt get back sooner. Everything on the deck is 100% new. All new spindles. Greased properly. New main drive belt, brand new deck belt and brand new deck drive belt. I had picked up a new steering drag link today and then I will install the deck once again. I can rotate the deck by grabbing the drive belt when its not on. It turns freely and not binding. It is a little tight but I'm pretty sure its due to everything being brand new. Once I get that far I will post what I find. Thanks again everyone for youre help. It's greatly appreciated...

Not that I could see..

So here is the update. I put the deck back on and trippled check everything.. the deck soes move freely if I pull it by the drive belt.. I had put a brand-new oem deck drive belt on it and now its way to loose after trying to engage the decknall these times. Stupid question. Would the belt stretch that much ?
After trying to run it the pto still does squeal. Plus just like before I rebuilt it. I would have to sometimes move forward in order to get the old pto to engage.
I have taken the pto off twice now to check for shavings or any other debris.. nothing. I also thought maybe the key was maybe slipping. But its solid.
This is all that I have done.. all new spindles, idler arm bearings. All new belts. Main drive belt included. I also put on a new pto switch.
I did record a little video however, no matter how much I shortened it the video was still to large to upload. So, I put it on my personal YouTube channel if anyone wants to hear the noise that I am talking about. I couldnt find my little tripod otherwise I would have recorded it from underneath..

I appreciate any help..

My hearing is shot, but I hear more of a grinding than a squealing. I see from the evidence the belt is rubbing the tensioner arm, as in the black paint is removed, exposing yellow and bare metal. But that would happen only if the deck was adjusted wrong, so it would only happen if the deck was at full height when engaged. To me, it sounds like grinding, which tells me the clustch in the engine mounted pulley is having issues. Is the PTO a switch? or a lever?
