Like many others, Mike (Parax) already bought the new Tractor with Trailer (8063).
Below some photos, where we can also see some differences among the two 2twin" tractors (8063 vs 8284), besides the evident replacement of the old panels by new ones whose design is aligned with the series of TECHNIC panels.
- Red - Not a 'long pin with bush', so liftarms raise higher (above trailer). Trailer will not fit 8284 without modification.
- Green - Built in spacer on 8284 not on 8063, so does not interfere with trailer.
- Blue - Longer transmission axle, so the rotary equipment from 8284 will not fit 8063 without modification.
You can also find some other side-by-side photos, from Mike's Brickshelf folder.
