A D4 with a 10' blade? Must be a LGP for that small of tractor to have that size blade. If you have a lot of dirt to move, he is going to be there a long time. Also how old is it? Cat has made D4s since the early 50s. A new hydrostat D4 is a whole nuther machine than a cable operated steering clutch machine. Not all D4s were created equal.
For comparison, I used a 2006 D6N diff steer along with a 65E rubber track tractor and 12 yard forced ejection scraper and it took us plenty long to do a 3 acre pond. But we did have to move a lot of dirt.
If you have a big ravine and mostly pushing up a dam might be ok. I guess back in the old days, they built dams and stripped coal with mules and a slip, so if the operator is tough and you have plenty of time, it can be done. Maybe he is bringing in more machinery after the clearing part.
