Welcome to TBN!!!
The 47 backhoe was for the 4200, 4300 and 4400 as well as the 4310 and 4410. It's really too big for the 3005 tractor (which uses a #7 backhoe). Could you make it fit? Maybe, but you'd have to fabricate you own brackets and subframe. The hydraulic flow would be the more expensive problem. The 3005 doesn't have the GPM required.
