snow plow = driveways
driveways = paved to concrete, to side walk curbs and like.
if you are driving fast, and hit a corner, say on a crack on concrete driveway. you have chance to twist the loader arms. and bend them out of shape.
if you have a plow that has a "trip" function. basically if you hit something. some springs take in some force allowing the bottom of the plow to bend backwards hopefully allowing the blade to slide up and across the given unknown hidden obstacle. and hopefully no damage to the FEL arms.
if you are in a parking lot, with bumpers for tires in the parking lot. and hit one of them, the trip function of plow should allow it to bend some, vs busting up the bumper / messing up your plow.
the twisting of the arms of the FEL that are of issue. and with snow plowing, you may have blade angled side to side. so you move the snow all off to one side. causing extra force on one side vs other side. that could possibly twist the FEL arms. the faster you go, the more forces on the FEL arms, and higher chance you twist them.
=========
do i have a plow no, have i seen a few FEL arms twisted personally yes. along with many other threads here on forum of folks twisting there FEL arms.
have i gotten away of no major damage to the 555c TLB (tractor loader backhoe) i have, most likely, i have seen the arms twist some, (one side higher vs other side) when trying to deal with stumps, back dragging, general digging with FEL. but i was moving slow and had a chance to correct things before things went ugly. and i had a line of sight of what was in front of me.
snow plowing... woops there is a pot hole blade corner just snagged, woops there was a big crack in driveway... woops, didn't know about that curb...
