I haven't followed that thread. Anyone who actually tries a diesel powered 2 wheel tractor will never think it trivial. I think the Goldoni weighs about 400 lbs. The dealer told me he's had some rather hefty folks try to stall one. Didn't happen. The torque of the diesel is very noticeable. The Goldoni at 12
hp has 1/3 the power of my Kubota L3710. I've run Gravelys and they're great machines but the Goldoni is in a different class.
Lots of European companies make attachments for the machines. I've got the literature for a backhoe and a mini round bailer. The Ferrari tractor website has pictures of a seed drill, and a flail mower among others.
