Case 621B or Case 721D

Im looking for a wheel loader to load feed and do some work around the farm. My question is which one is the better Value? Both machines have around 9,000 hrs on and tires are about 50% on both machines. Neither machines have a quick attach. Both are in good question. The case 621B has a brake pressure light that flashes but will go away when you run it for some time. Other than that both machines are sound and are in good condition. Any feedback on either machines i would greatly...
