Having not experienced Deere's previous two-pump design, I can't offer an opinion on how well that worked. However, I have demo'd (and bought) their single pump unit on both a 757 and a 777 and thought its performance was outstanding. I do have reservations about the single case/dual pump design but time will tell if they are well founded. But from a performance standpoint, the setup works as well as anyone's dual case/dual pump setup, such as Scag's, exMark's, Toro's, etc. I demo'd all of them to compare and demo'd the Deere 777 side by side with a Turf Tiger - equal performance in my view from the hydraulic system standpoint.
