Exmark Z engine slows down when engaging blades

On first lawn all is good. On second lawn blades start up slowly. Now blades are dragging engine down. Pulled belt all pulleys seem fine. Engine runs fine without belt on. I now here a clicking sound from clutch now and then. It acts like bearing is heating up and causing excess load but all spindles are only warm to the touch. I called clutch mfg and he blames spindles but they all seem smooth running.
Any suggestions on trouble shooting issue.

Any suggestions on trouble shooting issue.

With out model number, engine etc etc.....I could only guess.

You have a Multimeter ?

How old is your battery ?

What I would do is:
If you don't have the manuals for your machine, go to the Exmark site and put your numbers in and get the manuals....

Make sure your connections at the battery are tight, make sure the ground at the machine is tight and clean.
Test the battery at the terminals. You should have 12.6 volts. With the engine running, you should have 13 + volts
If the battery is 2 years old and has 12 + volts, it could still be bad, get it tested....

Clutch could be going bad if you have a couple thousand hours on it.......

Check your idler pulleys too, bearing maybe dry.
