As I have been through this twice, I will say emphatically GET THE BALE OUT! Once the bale is engulfed in flames, there is really only one way to extinguish it. It will take a large amount of water, i.e. fire truck.it Is hard to determine what to do when you see smoke. Some say not to raise the tailgate and have had confirmation from one unfortunate person that as soon as the tailgate was raised the baler erupted into flames. The assumption being air reached the flames when the tailgate was raised.
I agree. IMO, A leaf blower is a basic baler maintenance tool--just as important as a grease gun. I blow mine out when I'm done every time I bale. Chaff also collects heat and grease -- causes extra bearing and chain wear.Another easy thing to do is use a leaf blower and blow the chaff off as often as possible (I do it at the end of everyday minimum and sometimes I do it during the day if I have a few minutes of downtime). A baler that is packed full of fine chaff makes it that much harder to extinguish a fire. The cleaner the baler the less fine fuel their is to ignite.
Well, here is another of my thoughts that everyone can disagree with. The hitch pin size I like to see used with a NH round baler is 7/8”. Two reasons, hay in our area is not grown on flat bottom ground, but on hills where you run into situations where the baler is still headed downhill while the tractor is headed uphill. If you use a pin that fills the hitch holes there is a lot of stress put on the drawbar and baler hitch. Have seen numerous larger hitch pins bent from that situation.I guess I should practice disconnecting the tractor from the baler quickly. I have a simple pin with a latch on top, however, that pin gets into a bind and makes it hard to pull out by your hand without using the jack stand.
