I spent several years on a Bi. and for haying/ feeding/ cleaning, thay can not be beat. you will not be able to use it as a farm tractor though....no slippage. we tried it on a scraper, and a harrow, just not an ideal situation. put a shredder on it, and you can mow all day long and never twist your neckONCE to get close to something.
I had a big upheaval this spring, and I am no longer tied in with the bi...so I spent this summer on a 7520 JD.... was a great loader, and used it a tad bit in the field....no big problems, but you start loading 5 or 6 semi's a day, and you sure miss the bi.
