I totally agree with previous posts that say it depends on the implement's flow requirements, that loader auxiliary ports are generally not real high flow, and that heat may be an issue.
Currently I use a 6' 2-stage snow blower on my loader with a 21 gpm Prince pto pump and a reservoir tank on the 3ph. The rear pump/reservoir and the blower are connected via two, 20+ feet long 3/4" rubber hydraulic lines. It is PLENTY of flow for that snow blower. I do not use a cooler...winter temps and snow dust keeps temperatures in check.
I'm looking at a loader mounted hydraulic leaf/debris blower. The manufacturer specs are based on 16-18 gpm. It will be used in warmer temps than the snow blower, so a cooler may need to be added.
Some manufacturers will size the hydraulic motors in their implement to a customer's available flow. That was the case for my snow blower. Just remember, there is no free lunch here...if you size for more rotational speed, you'll lose torque (and vice versa).
Oh, and as a previous poster mentioned, use the correct valve. I use a 3-position Prince motor control valve. (Forward, Neutral, Reverse) When placed in neutral, it allows the hydraulic motors to free-wheel. Rotating mass and sudden stops are a bad combination! And don't forget some sort of over-pressure device. (The Prince motor control valve has one and the snow blower has another.) If the implement jams it effectively dead ends the flow, causing excess pressure.
And hang onto your hat...this stuff can get expensive! Seriously consider the "buy once, cry once) approach.

I have had this auger drive for 11 years.

I have drilled thousands of holes with it both with skid steers and a lot off of the stock hydraulics on a case JX-95 tractor. I havent tried it yet as I just got the tractor but I intend to run it off my Kioti as well. it worked fine on the tractor but Skid steer spins it a lot faster. in fact my skid steer spins it too fast so on the skid steer I dig at idle. Torque of a hydraulic motor is a function of the pump displacement and pressure. GPM determines the speed. I’m sure at some point if the GPM is too low it simply won’t work but on the tractor it has plenty of power just turns slower.
