You can throw the hay narrow enough to bale behind the Mower but it will not cure as fast. Where do you live??? Some times in real dry climates they do throw the hay into a windrow.
Triticale, is a real juicy crop it will be tough to bale even with it spread out wide. It takes a lot of air/sun/time to cure dry enought to bale as dry hay.
I have raised it here in Northern-Iowa and I always had to chopped it as silage.
