Thanx for the info Lynn, much appreciated.
B/c of the size of the 850's bucket, I don't know how much I'll use the 850 to dig/load trks. I'm thinking I'll build a ripper tooth and possibly mount a large, powerful, slow turning motor with a grinding head to mined the earth so I don't have to do anymore hand digging. That'll also slow down the excavation too, make it more scale, win win.
weakco, that's a great acronym for them... but yeah, we don't need to discuss that garbage anymore, it's broadly known.
