What are straw blocks please?
Not completely sure, either. I'm gonna make a WAG and say they're the same as the "hay dogs".
Those are the spring loaded "fingers" that pop up in the bale chamber and hold the hay in place after the plunger has compressed each flake or charge before the bale has been finished.
There's 13-14 flakes or "charges" per bale and the hay dogs keep them from falling down or bending over, etc. before the next plunger stroke.

The spring-loaded hay checks (aka hay dogs) in my MF124 baler are on the top and bottom of the bale chamber (3 on top, 2 on the bottom). The wedges are installed in pairs on the side walls of the bale chamber, which is pre-drilled to accommodate 3 pairs of wedges. I use one pair of wedges for my oat hay. These wedges bolt onto the bale chamber side walls and are not spring loaded.
So, the "straw blocks" are the edge that the plunger knife cuts the oat straw or hay against.. You add or subtract wedges depending upon the material you're baling?

Hmm... looks like the wedges function like a horizontal rail that support and/or keep the plunger head in postion.
But.. you said that they're 1-3 ft. downstream of the plunger? Maybe I'm not looking at the pics and seeing what I need to!!
Thanks.
