This one guy on you tube did that on a murray he had - pretty much for buzzing around with . I can tell you that owning a few stock 5HP tractors, you wont be able to run a deck with a 3HP motor - 5HP can barely handle it.

Your going to need a cast iron flywheel or a heavy pulley to put on the crankshaft since its a push mower engine. It will kick back with out it.

just use a pushmower engine for riding around on a flat surface because it is so limited on power

I don't understand what happens when you try pull starting it without a blade. I know the engine was designed to have a relatively heavy flywheel (blade) on the output shaft, just didn't know what kind of affect it would have with it missing. Does the engine jerk back in reverse rotation when it doesn't start because of the compression stroke?

the pulley would be enough weight for it but you wont have torque but it would be good for speed with i good pulley swap

3hp in a tractor built for 20hp is hardly going to be able to move it.

In a smaller RER it would work,
