Hesston 1840

Ok so I had a weak moment and traded my tired tried and true 348 in on a new 1840 Heston with a Harvest Tech Fully automated applicator. I've done a ton of reading and comparing specs. It was either going to be a Hesston or a new hayliner and the deciding factor for me was ease of transportability down the road when pulling my accumulator. In my reading I remember someone here saying they had installed special straw dogs inside the chamber of the 1840 for baling straw. Can anyone that runs one of these machines elaborate on this. I do bake some straw in the summer from time to time and I'm wondering if it is something I will need. Or maybe I completely misread the thread.
