What the heck kind of baler is this??

Got a question for some of the old guys, as they're the only ones who would know... What kind of baler is in this video?? Never seen anything like it...

It's a SIDE DISCHARGE square baler... the press chute is coming out above the LH tire and spits the bales out the end, and it's got a  weird bale chute to give them a quarter-turn so they drop into lines like a regular baler...  Just totally weird and I've never seen anything like it.  First question that comes to mind is, "WHY??"  WHY would you want to arrange a baler that way... I guess less shaking back and forth on the tractor as the plunger moves back and forth, since it's going sideways, but HOW does it feed the bale chamber?? I mean it's obviously got a side-pickup like every other square baler had until they invented the inline baler (which feeds from the bottom obviously with the bale chamber above the pickup) so I suppose that the pickup would be feeding the hay onto a table behind it and then a stuffer tosses it into the bale chamber in time with the plunger... but then you have to have the gearbox hanging out over the RH tire... and how do you transfer power to the gearbox and flywheel-- complicated PTO arrangement or PTO running a 90 degree gearbox with a cross-shaft, with another 90 degree gearbox to spin the flywheel??  Or is it engine powered and belt driven??  

 

Crazy looking thing for sure!  Later!  OL J R
