pto pump

[carasel]

my tractor is nh tn55. i've got a roller bearing pto pump. fits on the pto. with 2 chains. i can't see a good place to secure them. any one have ideas.
the directions say you can bolt on a piece of angle. to the tractor. to attach chains. this i could do if i can figure where to bolt it on. any help/ideas would be appreciated. thanks

I bolted a peice of flat metal to the pump and attached a chain to both ends leaving a loop of chain dangling. It just drops under the drawbar, thus preventing the pump from rotating.
