I recently became the owner of a John Deere 400. It is a great tractor with lots of capability. With that said, the attachments are hard to come by because they are not interchangeable with other models. The attachments made for the 400 were ONLY made for the 400 and thus are rare. The rarity also increases the price.
The snowblower made for the 400 was a single-stage 46" with hydraulic lift and hydraulic chute rotation (so this solves the issue of getting off the tractor).
If the price is right on the 400, I say it's a no-brainer. If you are patient, you will come across the attachments. If you aren't patient, you may also have luck converting a snowblower for one of the newer models by modifying the mount and finding the appropriate length drive shaft.
On another note, the hard cabs are worth as much or more than the tractor in some cases. Post pictures if you get it!
