That combine will pump the green straw through, no need for swathing or even spraying if you have good Sunnybrook parts in there. If running that rake-up don't make the mistake of running it too fast. They work good at slightly slower than ground speed and last longer. There is longer rubber flaps to help with seed loss, we used to do a lot of grass seed and it worked good for that.
