LEGO Tractor (Technic > Expert Builder ) | Rebrickable – Build with LEGO
Click for an animation of the lift in motion. Steering The front wheels can be steered using a wheel in the cabin.
The wheel drives a 16 tooth spur gear used as a pinion through a universal joint. The pinion drives the steering rack. The steering mechanism itself uses the new control arms and toothed links as shown in the computer image.
The connection between the steering rack and arms is knstructions elongated in this model due to the height of the model above the wheels. Click for an animation of the instructuons in motion. Engine This set features a front mounted 2-cylinder inline engine. The engine uses the offset axle holes of the 24 tooth gears to make a crankshaft.
Connectors placed end to end and clocked 90 degrees form rods which connect to 2 specialized 2×2 square pistons.
The “cylinders” are actually square. The engine is connected to the rear wheels via a large number of gears as can be seen in the computer image. The engine is hidden under a hood which is hinged and has an attached rod to hold it open.

Click for an animation of the engine in motion. Implement Lift The implements can be lifted with a 4 bar linkage connected to a ratcheting lever next to the cabin via a set of translating racks. The translating racks interface with a 90 degree crank arm built from the new toothed elements. The implements remain parallel to the ground as they are lifted.
A beam on one side interfaces with a 16 tooth gear and acts as a ratchet pawl to keep the implement from descending under its own weight. Plow The plow features a series of 4 offset tines which are spring loaded with rubber bands.
These can be lowered below ground level to create furrows. Instructions for a number of other implements are included with this set including a seeder, a tiller, and a thresher.
Some of these require parts from a supplemental set to build. Click for an animation of the plow in motion. Differential The rear axle uses a instructkons gear.
It incorporates a built in 28 tooth ring gear which can work either as a bevel or a spur, similar to the 24 tooth crown gear. It is made to house 3 of the new 14 tooth bevel gears. One is on each axle, and one planet gear in the middle allows the axles to turn at different rates. This PTO does not drive anything leto the basic model, but various attachments could be added.
