851-1 Red Tractor 40 Years Anniversery Edition




Lego set 851-1 was my first Lego technic set in my childhood and one of my most liked ever. To the 40 years lego technic anniversery (1977 - 2017) I now have built a retro model in the same dimensions and color with new style Lego technic parts. This is the result:

- 1:1 dimensions and color style to original 851-1
- 1 cylinder engine with flywheel
- openable hood for engine
- manual steering for frontwheels
- free suspension for front axle
- rear drive shaft for farming devices
- manual lift up and down for farming devices
- Tedder (Heuwender) with 3 wheels spinnig fast when driving
- 40 years technic anniversery brick included

- Initial 3D CAD design made with stud.io and optimized with MLCad
- Full PDF instructions generated with LPub3D

    What a great build! I would definitely buy this set in the shop. Why didn't Lego think about that with the 40 years anniversary? ;-) People want this... I loved the 851 set, but yours even has extra functions. Excited to build it, many thanks and compliments.

    A great idea for the 40th anniversary of Lego. Yes the old tractor now in a new look, I like it quite well. Thanks for the instructions!

    While the 40th anniversary MOC is cool, what I think is cooler is that you kept the original set, and able to build it with all of the pieces. That is some LEGO heritage!
