Backhoe 4720 BH attachement

[rsss396375]

I've tried to some research on this, but alot of different combo's. I am looking at buying a 4720 with a 7' scrapper/ripper, loader and mulch mower with 567 hours (2005). What is the best Bh for this setup. I will need it for installing vineyard watering pipe 8" and a swimming pool in the future. I would greatly appreciate any pro's and cons. This is a great website and feel free to comment on the price. I'm not a real expert on tractors and this would be my first.
thanks Dino
