Justin your finding out why three point back hoes are not very popular anymore. The better ones actually have a complete hydraulic system ran with a PTO pump. The hydraulic flow is in the 25-30 GPM.
The hydraulics on a JD 4010 just are not in that class. They where 13 GPM ( This what my IT manual says). That will seem real slow compared to an actual construction back hoe.
As for "power" most three point hoes seem that way. Most tractors just are not as heavy as a "real" back hoe. So the designers usually do not have real large bore cylinders on the hoe. Look at the boom and stick cylinders compared to your Case back hoe.
Also your JD 4010 is a 2250 PSI system. Many modern back hoes run 3000+ PSI systems. I just looked up my JD 310J hoe's flow/pressure. It is rated at 28 GPM with 3650 PSI at the hoe, 3200 PSI at the loader.
So the grand sum of it a Three point back hoe is limited in speed and power compared to a industrial hoe.
This is why small track hoes are gaining market share. They will out dig just about any three point or even skid steer back hoe attachment.
