Hydraulics and three point hitch ?

[HK45]

I have a CT450 WITH backhoe. Today I noticed If I have the Hydraulic on For my backhoe, I cant move the three point hitch up or down tell I turn the hydraulic of to the backhoe Is this normal?

Yes, that is normal. The rear remotes are in-line in system ahead of 3 point valve, so when they are engaged the oil is dumping to tank rather than flow on to the 3 pt.
