About the pull the trigger on a 6' rear blade for my BX2380. The Blade i'm trying to get doesn't give the actual angles of the pin holes. I could call (and I will if I need to) but was wondering if there is standardization generally speaking with angles on rear blades. It looks by eyeball about 45 degrees at the max with the middle hole being about 1/2 of 45 or 22.5 degrees for both forward facing and rear facing holes. Is this accurate for most rear blades? Just trying to figure out how much plow width I have at different angles and if i can store the blade without exceeding my rear tire width.
