Yes I agree. It looks like a real three-stage gearbox.
Overall, I liked the idea to combine a 3-set - it brings more variety. But this processor looks like something small. Take a look at the number of parts of three sets: - 42057 = 199 pieces; - 42061 = 260 pieces; - 42063 = 603 pieces; Total 1062 pieces (it is a not bad quantity) In appearance harvester consists of about 500-600 pieces. It means that a lot of pieces is not of used. IMHO, this reminds combine dial 42048, an improved version, they differ in that: - Added 1 step in the gearbox; - Added to the suspension on the rear axle; - Added 3 cylinder engine; - Added vintelyator on the engine; - Added 1 seat for the passenger;
Except for the suspension, the differences compared with the 42048 is not very principled. In principle, it combines several sets - it's a good idea, but I would like to combine was more technically complicated and more functional.
