I’ll have a go…

If this is one end of a 2×4, first sort the material and mark the good end and stack for next operation. Discard any with knots near both ends.

Use a band saw and a mortising machine with a modified chisel.

Band saw obviously would be set up with a fence and a stop. It would help to have some roller tables or stands to move the material to the operator and away to be further processed or stacked.

Use a 3/4” hollow chisel. Modify the hollow chisel by cutting away 3 sides, leaving only one side of what used to be a hollow chisel. Throw away the drill bit and you don’t even plug in the mortiser. Now it’s just a straight chisel with a lever to push it. You’ll have to sharpen it after every 100 or so, so you might as well have two of them. Chisel will be weakened by removing the 3 sides, so material needs to be held very stable to avoid breaking the chisel.

Use fences and stops to position the work for consistency. At both stations, cut, flip, cut, next.
