Looking at a few chains, one is the Oregon 73BPX which is Semi Chisel, it has bumper ramps,
the other is the Carlton A2EP Semi Chisel which has no bumper ramps.
Question is, all else being equal, does a chain with bumper ramps use more power to pull
it around as opposed to a chain...
no bumper ramps
I want a new chain for an 18" 3/8 .58 bar.
The chains main task will be to cut through a bunch of 3-4- and 5 inch logs
stacked in a frame, 3 logs wide by 5 logs high.
Unfortunately the logs may have grit or dust on them from laying up before
cutting so Semi Chisel will be better...
