I would disagree with the Hon. Member.
There is nothing wrong with compact tractor, just avoid Chinese cheapies... Dunno what your budget, but if you can find a low hours 30hp Kubota or Kioti, you will not go far wrong. Even better get a front end loader on it, and you will constantly find uses for it, even if a lot of the work is as a motorised barrow!
Loads of cheap attachments about to do small tasks, mowing, harrowing etc that will be quite adequate for your 5-6ac.
Good luck, and have fun!
TBH, I wouldn't want to spend more than £20k including attachments (which I assume would be a flail mower and a loader to start with).
