Lift and link pins are usually hard.

If you can get grade 5 or better grade 8 bolts, that is the way to go. They ar made from a alloy steel stronger than regular steel.

Don't forget to grab some locknuts while your there. Since the bolt may have a tendancy to spin it will keep your nuts from falling off.

A 3/4" pin made from mild steel (A36) will hold 10,000 lbs in single shear. The top link pin is in double shear so it should hold 20,000 lbs before failure. How much do you think your force will be on this pin? It's not clear in your post as to weather the pin is in shear or bending.

I wouldn't monkey around with mild steel hardware anywhere on a tractor lift that supports weight. For the few extra pennies to get gr5 or gr8.. why not have that extra margin.
