Called LS Tractor, Rick the service manager for the North East said my BH is the correct model / specs for the tractor, so I'm ok with the model # thing. He also confirmed I have to loop the hoses once the BH is removed. After looking at it again, it occurred to me that I might be able to switch the male / female quick couplings on either of the two hoses and then have a male / female that I can connect to complete the loop, so looks like I'm good there. Now hoping for the weather to get a little better so I can spend some time on her.
