Anybody remember what the Gallons per minute at full flow to a cylinder should be for both tractors. 620 holds 2 quarts less; so not sure its the same GPM.

| 620 = 10.1gpm at no load; 8.5gpm at rated pressure
720 = 10.8gpm at no load; 9.1gpm at rated pressure
720D= 11.8gpm at no load; 10.0gpm at rated pressuresystem capacity has nothing to do with the flow rate of the pump it's pump displacement and pump speed that determines flow minus any flow restrictions inside the system
I've found that anything within 1gpm of factory original is still pretty good for most work if you're using them

| I found an old post by F-I-T where he stated the 70D was 10.8 GPM and that the 730 used the same pump. TractorData says 8.9 GPM for the 620.
