Yeah I understand your frustration. One would hope you could use all three if desired. Sounds like the BX25 is superior in this aspect... Something else for me to consider in my shopping.
Thanks for your info and feedback! I'm sure the install and removal of the arm will speed up with practice. How many parts must be installed?
First I have to remove a set bolt that locks the rod that the 3 pt arms attach to. Once this bolt is free, I have to work the rod to the right. Then I mount the left 3 pt arm and connect the locking pin to the 3 pt arm to keep the left arm in place. Then I have to work the rod back to the left and re-set the bolt that locks the 3 pt rod in place. Then I attach the left 3 pt arm to the left lift as well as attach the sizing linkage. I was able to do it all in about 10 minutes this weekend and hope it will get even easier when the rod loosens up.
