I was thinking that that machine must have been an unpopular machine to drive in its heyday.
First, I can imagine how much it would lurch forward and backward with each stroke of the plunger. Balers make most tractors rock, but that thing must have been like a fairground ride
Secondly, it must have been pretty damn noisy. Especially considering you are sitting right on top of it.
Thirdly, it must have been really dusty sitting so close to the knives and ram.
But still, it was an interesting idea. I saw a photo of a self propelled round baler in a magazine before that was used on really steep slopes. Some guy had made it himself with a new round baler and half a tractor.
