Those plows don't have a great deal of trash clearance under the best of conditions. The #66 (trip beam version) has a LITTLE more. It wasn't until the MF #43 that they had a high clearance light draft plow.
Coulters should be set 3/8" to 5/8" to the land side of the bottom. I've had the best luck with coulters cutting 2" to 3" deep. If the coulters are worn significantly, that depth will put the coulter brackets too low where they'll catch trash rather than help the problem. From the pictures, your coulters don't look worn.
There isn't much in the way of adjustment for fore/aft on the coulter brackets. Only left/right and up/down.
I'm in agreement that the plow in the picture needs to be scoured more to help get a good "flow" of dirt/sod/crop residue through and under the beams.
I use a MF #66 plow (again same basic configuration, but trip beams) I've had MUCH better luck since I installed cover boards (aka trash boards) If you do use cover boards, set coulters farther to the land side. (I set mine @ 3/4" to the left)
Long story short, this isn't UNcommon with older 3-point plows that weren't really designed to deal with trashy conditions.
