I AM 70 YEARS OLD AND DISABLED
I HAVE A CUB HDS 3185
WHEN THE MOWER STARTS AND YOU ENGAGE THE BLADES IT TAKES ABOUT 10 OR 15 SECONDS FOR THEM TO START, THEY DON'T TURN FAST ENOUGH TO CUT AND THE ENGINE CUTS OUT ?
I CAN'T FIND THE PTO , ALL I SEE IS A LARGE GEAR WITH TWO BELTS, THEY SEEM TO BE LOOSE, COULD THAT BE THE PROBLEM? IF SO HOW DO I TIGHTEN THEM ?
NO, THERE IS A SWITCH BY THE STEERING WHEEL

By gear...I guess you mean pulley.
I am not getting enough information from what you wrote to understand.
Of course...belts that are lose will not be turned or turn pulleys etc.
Some times belts are loose before something is engaged...don't know if that is the case with yours...I don't think so.
Are both belts loose? that would be even more strange.
You may have broken or lost a tension spring on the deck that would explain one being loose.
Yours is a garden tractor...I was looking and you have a brake rod that operates a tension spring(my opinion)
See if it is there.
