Hello all: This is my first post. I have read some of the posts for attaching a post driver to a tractor and am still very confused. I have a john deere 4400, a great little tractor, bought it new and still love it. I want to buy a shaver 8d post driver and attach it to my tractor. My tractor has no rear hyd. and does have the 420 loader. Can someone tell my the best way to get rear hyd power for that driver? I have been to the john deere dealer and saw the rear kit but still do not understand how it attaches. Also, If I put the jd kit on do I still have 3 pt power? Thanks for any help.
