John Deere ride-on mower losing cutting power

I have an old LX 176 riding mower. I have replaced almost every part, now it looses power in the blades to cut even moderate length grass.
The only belt I have not replaced is the one to the cutting deck. It looks in good condition, could it stretch?
I have now also ordered a new PTO clutch, thinking it may have lost strength putting the power to the blades?
Any other ideas would be appreciated.
Cheers
John

Check the pulleys along the belts travel to see if they are worn, if the belts bottom out they lose their effectiveness, vbelts should not touch the bottom of the pulley. Have a good one. Geo

Geogrubb's suggestion is good but the same condition exists for worn pulleys or worn belt on the deck, Being pulleys are steel and the belt is rubber. I would start by changing the belt. If the belt tensioner on either the drive or deck belt is at its travel limit, its time to change that belt.
