Seems to me its just the 16 gpm pump, but it's plenty fast for loader work. It's a pretty plain Jane tractor (standard transmission, 3 ranges with 4 speeds in each, nsl loader) but is very handy as a loader tractor. We bought it new this fall and it did make a trip back to the dealer early on. It got pretty cold out and the crank case vent froze off causing the crank case to over pressure. This took out the rear engine seal and the exhaust filter. Turns out there is an update to prevent this from happening and that is now installed. I think that cost New Holland a fair chunk of change. We only have a couple hundred hours on it so it has yet to be determined if it is actually a good tractor or not, but it is nice to use. It actually feels more stable handling bales than does our T7.210
