Why are you pulling the enghine?
If it is for the clutch? Why take of anything from the enghine? I strap( lifting strap in good shape) the engine, just a little back heavy, and with the chain falls( come-a-long, chain block) to the front. I have to watch using a one ton chain block you can lift the wrong thing and break something.
If it is engine work take off the oil pan. May need to add a couple of wood blocks for spacers ( so that your able turn the enghine over(to be clear of the crank) if need) before you lift using a strap .
I don't like chains to lift the can cut into or crush something ( if you are wraping it around ).
Try to leave room to move the tractor if needed, it is on wheel and easy to move. The engine is out is not the time to think , boy it would be nice to be able to set it in a truck. Or lower it down to put on a enghine stand. Also make sure wheels are blocked up and breaks are on. If you put it in gear the engine is not going to hold it, and the tractor should be it neutral any way to pull the engine.
Be safe and look twice !!
