I have a bradco 611 mounted on a kubota 3710. The combination is not recommended by bradco for that size of tractor. Great backhoe. Recommened hydraulic gpm is 10-12. Very nice mounting system. Mounting plates are very rigid and heavy duty. Yours may differ considerably but overall it will have similar 4 point mounting plate. The 611 may be recommended for your size of tractor but I doubt it. I also have a JD 5300 (54hp) and it is recommended for that tractor. Call bradco at 800-922 2981 and they will tell you if they feel it is compatible. They will even fax you pictures of the mounting plates, pto pump (if desired) and power beyond kits. I run mine off the tractor hydraulics (7.8 gpm) and it seems a little slow at times. 10-12 gal/min output is probably ideal. I am considering a pto pump.
The woods 9000 is a fairly large backhoe for compact tractors. I dont know the specs for woods but is the 611 worth the additional cost for the increase in power? I have to admit, at times I still wish I had more curl and dipper power.
