I'm still looking for a used 673-873 or S220, 250 Bobcat. I want to run a stump grinder & brush hog. For a brush hog I'm thinking of getting one for a PTO three point hitch and getting a Bobcat PTO pump to mount on the Brush hog. Then weld a quick attach plate to the front of it. So I won't have to mess with the 3 point adaptors. I also want to get a hoe, dozer blade, & grapple. So do I need Hi-Flow? Or should I just look for a Machine that pumps 18-25 GPM @ 2500-3000 psi?
