Dad has a new holland I think it's name is a 275 maybe. My grandpa bout it new in 1969. It has never been rained on. Who knows how many bales its made. Last time we used it we baled up about 1500 straw bales and once got the pressure set I think it only missed one bale. It's a very good machine, but only works with sical twine. We've tried plastic a couple times and it misses more than it ties with that stuff. Anyway no matter how you make them and what the bale is made of they still suck to pick them up!!
