Ummm that's what hydraulics do, create power. Yes, it takes engine HP toturn the pumps but excess HP is just pissing $$$ out your exhaust filter <- yes tier 4 uses a exhaust filter.
In all the years selling these Deere mini excavators, I've never had a complaint for lack of hydraulic power and I can not ever recall a time while digging with them myself taxing the engine to stall out. I've put my fair share of hours on most all our size minis except the 27 and that's only because we don't stock many of that size.
The design of the hydraulics in our mini excavators don't require excessive HP to turn them while under max load.
The Deere 60D was the only mini with an econo / power switch. Now the new G series it will come in most of the models. Power mode for hard digging and econo for light excavation work.
