Can't tell if he's in 2nd or 3rd - I'd guess 2nd

I too had never seen / heard of bale throwers before seeing them on youtube. Seems a pity to take away the opportunity for teenagers to develop some strength over summer. When I was a kid, we had no shortage of schoolkids wanting to earn money by haycarting. I spent three summers at it and it was a highlight of the year for sure, although looking back it meant I missed out on the beach and girls : ) at least for part of summer
I also like the involutary swerve the cameraman took as the bale came flying out of the baler : )

Almost all the bales I carted were produced by an International 440. I can't imagine how many bales that machine produced as it was already pretty old when I started and I was involved in moving 250k bales over those three years. One excellent mod the boss made to it was to fit a blower directed at the knotters to keep them clear - worked a treat. The blower was belt-driven from the flywheel. A mechanic at the IH dealership that came to work with us liked the baler because he said that all the timing measurements on it were one inch, so he said it was very easy to time after fitting new bearings. The other thing I liked about it (and many PTO implements are like this but some aren't) is the placement of a support bearing the same distance back from the hitch axis as the tractor output shaft is forward of that hitch point, meaning a nicely balanced pair of angles so when turning, driveline mis-phasing was reduced. Still had an angle at the flywheel which they could have handled with a CV joint but it was just a universal joint. Mostly ran that baler with a 2140 JD 2wd which was just about the nicest balanced tractor I've ever used. Superb to operate and really good on mowers too
Jim, you're probably right - couldn't tell from the angle how fast it was travelling
