Anyone have, used, or know about the New Holland T9.390?

We need a 4wd........must have a pto, and need NOT be a powerful horse.  Pull a 53ft field cultivator, a 7000 gal slurry tanker, and a 1000bu grain cart.

I am concerned about the ones we are looking at because they have FPT 8.9 motors, as compared to the 12.9.

Should I be concerned?

Thanks.
