Bar blades is all we have here. They are definitely not meant for mowing things like roots, rocks, large limbs, and the likes. Sorry about that comment but I plenty of bent blades and damage decks from such things.

As for the Briggs need the model number to give the flywheel retainer torque as you definitely want to at specs and not either under or over. Over tightening can the flywheel to break especially on some the newer flywheels.

As for pulling those puller holes are likely not tapped unless someone previously had removed it. I haven't used a Briggs puller since I started repairing these small instead used a harmonic balancer puller. One note those puller bolt needs to grade 8 instead the grade 5 or less I have seen on some those Briggs puller images.

Of all things please use the appropriate puller the next tech will thank you. I got flywheel that can't be remove anymore due someone over torquing it. On top they use hammer to get it off last time and mess mushroomed and cracked the crankshaft stub. This on a NLA crankshaft.

I hope that what LRT called a rattle gun is we here call an impact gun. The one I got would definitely break the flywheel as has a working torque of 950 ft-lbs.
