Possible bent 400cx loader arms on 09 4720 cab tractor

You might be able to make a correction by adjusting the leveling set-screws at the rear of each loader arm.. I've adjusted mine a couple of times while parked on level ground. I have the 73" hd bucket on a 300cx loader, standard is 61". I've asked a lot of it over the years (including catching rocks and stumps that didn't budge) and it's still nice and tight.

I think you're going to be putting a lot of stress on your loader with the snow pusher...

Good Luck! Let us know how you make out....

a few more, when some machines were stuck... actually for my own new driveway project alleiving the swamp on the one side with a new pipe, got every machine stuck at some point.. probably needed more like a 20 ton excavator lol

Any small deviation at the heel will have an exaggerated effect at the long end of the arms.
It could be a simple 1/4" adjustment where the posts attach to the sub frame, a worn oval attachment bolt.
Periodic torquing of fittings is part of maintenance that most of us forget to do.

A simple way to verify the arm geometry would be to compare the distance from pin to pin on each arm.
For the posts a digital spirit level should confirm if both are at the same vertical angle.

I am sure that you have 5 or 6 bolts on each side that attach the sub frame to the tractor any one of which either missing, lose or mis aligned would cause to bucket to not be level.

For an arm to be bent I would expect some paint to be chipping or flaking at the wounded spot.

Abuse it and at some point you will find out when you have gone too far. Just sayin... and you found out with this FEL.
Makes no never mind, but you now have to deal with the twist in the FEL that resulted from overloading one corner, regardless how you did it.
Good luck to you, and hope if you find the bend and get the FEL back to straight again, you will let us know how you did it.
