Yep it's kind of tricky the first time or two you install it since both sides need to do a 90deg twist coming off the
PTO to mate up with the idlers. It really is a very strong and reliable setup when routed properly. I've got something like 120hrs/4yrs on mine and it's chewed up BADLY from me not installing it right a cpl times and having it jump and jamb up.
