Never had an issue with clippings blocking their crops (14 years). I'm guessing that if it's a problem in the States (and other first-world nations) and not here, that it may be due to how it's cut, and how often.This makes me cringe...good way to get a clogged crop.
My grass is only 'mown' down once a month during the growing season, and they use a weed eater to whack it all down. I allow it to sun-dry where it lays before gathering it up... it looks a lot like straw when it's ready. Then just pile it up into a mountain for them to tear apart. The strands are quite long, and they usually are only interested in eating the seed end of the stalks.
Consider too that cargo straps work wonders when you need to move / reposition something like this. Following link is an image on amazon.com for illustrative purposes only as I'm not personally familiar with this brand.
