How to Build a LEGO Cutter

Assemble the base. Begin with the black double-axle piece. Insert the shorter end of a blue cylindrical rod into the two holes on the outside of the center section. Place a three-holed black oval piece over the longer end of the rods, followed by a 1-by-4 black block.

Build up the side. Top the existing side pieces with a 2-by-2 black brick. Surround this with two single-circle green bricks. To one, attach a white antenna holder. To the other, attach a white antenna holder with antenna. Underneath this area, place a flat gray base piece with the circle extending out beyond the side. Then, top the entire area with a flat black "Z" piece.

Add additional bulk. On the flat lower surface of the Z piece, attach two 1-by-2 black pieces with two short rods extending forward and backward. Top these with a 2-by-3 black base piece. Then, on the end of the upper surface of the Z piece, attach two single-circle black bricks, hooks extending toward the opposite side. Next to these, place a 2-by-2 green brick. Top this with two 1-by-2 gray pieces, extensions pointing outward.

Complete the front end of the base. On top of the assembly on the lower surface of the Z piece, place two slanted gray pieces with the slanted sides sloping upward on the outside. Top these with a gray flat rectangular piece (with a single circle on top). On each side of this, place a triangular green grill piece. Atop the single-circle green bricks, place an orange light cylinder. Atop the outside of the top level, place two triangular green grill pieces. Inside these, place a green flat 1-by-2 piece, and on top of this place a smooth-topped 1-by-2 green piece. On on side of the top array, place a gray control rod.

Add the cab and outside blades. Snap the black cab frame onto the top of the base, and attach the steering rods inside. Place an orange safety light on top of the cab, and a red accent piece on the front end of the base. Attach the two smaller blades to the outside hooks of the original piece used for the base, using the gray attachment pieces.

Begin the base of the cutter array. To one side of the front end, snap a green "arm" piece. At the end of the arm, insert a gray plus-shaped rod, with a gold, spiked circle on the outside end. Onto the center side of the rod, place a large black tire. Then attach the second green arm piece onto the opposite side (followed by a second gold, spiked circle). Place a red accent circle on the outside of the top of each arm.

Separately assemble the cutter array. Start with two 2-by-3 gray base piece. Over the center of these, place a black 2-by-2 brick with balls extending off each side. Surround this piece, front and back, with black 2-by-2 bricks with a single ball extending off the end. On top of the front end of this assembly, place two single-circle green base pieces with a quarter-circle extension off the side. Behind these, place a 2-by-4 flat green base piece. Behind that piece, place a 1-by-2 gray base piece with cylindrical extensions off each side. Atop each end of the section, place a circular detail piece.

Attach the blades to the cutter array. Snap a gray blade holder onto each of the balls on the sides of the cutter assembly. Using a short gray cylinder, attach an orange circular blade to each. For the front blade, insert a gray plus-shaped rod into the blade, and slide a hollow orange circle piece on behind, followed by a gray gear holder. Snap a black wheel onto the rod, then snap the blade holder onto the front ball, wheel down. Turn this blade piece so that the blade and wheel are both at an angle.

Attach the cutter array to the front of the cab base.
