My 1953 JD 14T baler can make shorter, lighter bales simply by adjusting the length measuring wheel. I've made some 1 flake bales on occasion and some 6 footers (by mistake) too. Then there's the question of how are you gonna pick 'em up and where will they go. My NH pick-up wagon likes a certain, fixed size or else bad news. Good for landscaping and temporary water stop measures, too. I also like the smaller bales for a 55 gal drum burner to keep the cold hands and tools warm during those special projects that pop up in only in cold weather. Baled weeds work great for this. Just the cost of using more twine, though.
