Soldaten und Bauern!!!
Our character today is a vehicle that, in the first instance, could never be considered a military vehicle. Let's talk about a rough, noisy, smoky weird farm tractor with a huge single-cylinder engine capable of burning almost anything, from diesel, crude oil, kerosene, vegetable oils and even lard. The character of our article is the Lanz Bulldog, a tractor that was born for the field and the farm, but was requisitioned by the German Government to serve in the German War effort in WWII. Come with me and meet this unusual, humble and irreplaceable warrior.

the tractor's technology of construction
|* In 1936 Lanz changed the performance data from "normal continuous output" (DL) to " maximum output over an hour "(HL). Thus, on paper, the 30 HP (PS) Bulldogs became a 35 HP Bulldog.|

- Air tires for the fields ensure constant operational readiness for use in the field and in the road without changing the wheels.

- Coarse maneuverability, equally advantageous in the field (small headland) and in tight areas.
- Immediate readiness to start thanks to electrical ignition (optional)

|Kojak overseeing the start of tractor's building...|
|The rear and front parts of the engine/chassis|
(left to right)
|The step 3 contains a challenge: only for experienced modelers... |
Man, the kind of phrase that Kojak just loves...
|The opening of the 0.3mm diameter holes was carried out smoothly and serenely. |
The bald one is really happy...
|The holes, in close-up...|
|And since Dremel has been "called for service" Kojak has opened|
the bottom hole of the hot-bulb, where the blow-torch starts to ignite the engine.
The idea is to make this part visible... let's see if this will be possible...
|...and Kojak also took the opportunity to remove the plastic (fixed) tow hook,|
which will be replaced by a removable metal one.
All holes drilled in this step, in yellow.
|The engine/chassis, in "belly" view.|
Notice the white rod.I replaced the original part with something more "straight".
|And the engine/chassis with "engine hood" in position.|
|Engine/chassis with "engine hood" in position.|
|Oh, man...it's all right, now!!|
|The bald one is happy as nobody!!|
|Kojak's little details...|
|The new metal spring done...|
|To install the new spring is easy: just glue two|
pieces of Plastruct round rod (0,8mm diameter) to serve
as a fitting for the new spring...
|The new spring in the seat's rod fitting (superglue) and...|
|The new spring with seat in position!!|
Indeed, much better!!
|Continuing the construction of the sub-assemblies: |
the exhaust will be painted separately, to facilitate the finishing...
The air intake "chimney" will be painted in the same color as the vehicle...
|Rear view of Lanz cabin...|
The rear rack is installed and lined up...
|Right side view|
|Steps 20 and 21: notice the tire treads...|
the chevrons must "point" to the same direction (step 21)...
The front wheels don't have this problem...
|The tractor with the construction completed,|
awaiting the painting and marking phase...

|While we wait for the tractor's glue to dry completely, |
let's begin construction of the trailer
|All parts fit together beautifully, without warping or twisting. |
Very well done, Ms. MiniArt!! Congratulations!!!
|The rear suspension is very well detailed!!!|
A real eye candy!!!
|Be very careful when building the rotation device, my Precious!!!|
|Checking the perfect squareness...|
|And the trailer was done!!|
|Now, the best part: markings and painting!!!|

Hmmmm...In the MiniArt design, the load is a little tighter,
almost no empty spaces (see yellow arrows)...
|But, as always, Value Gear is here to save the day!!! |
Man, I love these accessories!!
Much, much better!!!
|And a dry-run of the project. |
Now it's painting the Value Gear accessories and crew
