by originals do you mean the dearborn? I think there was a video on you tube but cant seem to find it right now. I would like to see one of those up close.
there are lots of trip bucket front end loaders too and some hydraulic rear end loaders. I know a 2n wont take a very big rear end without the wheels coming off the ground.
He said it was for use around a sawmill moving logs a trip bucket will work great in that application as will a rear end loader ,easier to steer comes off fast to leave tractor free for other things and the lifting weight is on the big drive wheels where it should be.
I dont agree with you on not being able to see as well I think its just the opposite but that depends a lot on the design of the loader. I can see A variation on the design of this bale spear being real handy.
put a cylinder in where he has the top link lose the top spear should work good around a sawmill . light weight and cheap to build.
