Meant to post up a little comparison of weights on a couple of bumpers on a BJ74.

I had always heard that the PTO and it's "porch" were really heavy and were the reason the front of the bj74 (mine anyways) had that "stinkbug" look.... lower in the front. It's pretty obvious the weight up front challenges the front springs. But what isn't obvious, until you weigh them, is the difference between the two. I found this very interesting

So here's what I found. weight's below and a Center of Gravity measurement. for the COG measurement I just picked a reference point which was the top mounting hole on the frame for the bumper.

Factory PTO winch and bumper = 185lb (5")
PTO shafts and blocks = 15lb (-30")
PTO box = 15lb (-60")
Total weight 215lb (-1.5")

ARB bumper = 100lb
Hardware/fairlead = 25lb
8274 with 155' cable = 100lb
Total weight 225lb (+6")

Well... there ya go. Don't let anyone tell you that big ole PTO winch and bumper are extra weight. That porch is definitely an obstruction, but it's not heavier than other winch bumpers and winch.

The ARB setup is 10lb heavier and the COG is 7.5" further forward.
