Good luck Mr. Jackson.

Check for clogged deck.also inspection of mower deck belt. Check for glazing or cracks in belt. That will slow blades down.

The clutch has an orientation groove on it that must line up with the pin on the mowers chassis. Once you line these two up, push straight up and then tighten the bolt. This keeps the clutch from turning while you tighten the bolt.

When you say 'going forwaed', is that while mowing or does it do it without the blades engaged or 'not mowing'?

heck the spark plugs for carbon build up

Exmark Premium Hydro Oil.

I was not able to find a cross reference.

My problem is that I don't know what your problem is exactly.
