The brochure for my TC29S shows a hydraulic lift pump capacity of 6.6 GPM and a power steering pump capacity of of 3.5 GPM. Is there any cross-over between these two systems--hydraulic lift and power steering? At my rear remote, should I expect 6.6 GPM or 10.1 GPM?

Vermonster, I'd say you'll have the 6.6 GPM or less. I say that for a couple of reasons. Since the 6.6 is the maximum for the pump, that doesn't mean you'll have that much flow everywhere. As an example, my Kubota specs call for 6.4 GPM for the 3ph and 3.1 GPM for the power steering, but the hydraulic outlet block says for a maximum of 4.5 GPM. So, I think I'm right about that; any of you hydraulic experts know otherwise?

Bird is on the right track. There is no commonality in the power steering and main hydraulic systems. You will measure something marginally below the hydraulic pump's spec at the hitch valve, loader couplers, or remote valve couplers; and remember flow is porportional to engine RPM.
