Ditto on the biggest square bales I've ever seen. Up around here it is all round bales (varying sizes) or the "regular" small square bales.
Don't mean to hijack the thread but here's my mine, baling coastal bermuda first cutting a month late in July due to spring drought. This hay carries my cows through 5 months in winter without any supplemental feed. This cutting yielded almost 3 tons per acre, will get 1 more cutting if we get some rain. Cured for 3 days, fluffed twice in ideal hot dry weather. 4x6 bales, 1300 lbs actual weight, per scale.
I'm only 1/2 done my hay, despite pushing to be done in June! Too wet. A lot of guys would say that TW is too small for that baler but seems to be working fine! No hills I suppose is the trick.
