Here goes golden oportunity for Lego to introduce 28 tooth straight gears... Looks like interesting parts pack

It seems that it has gearbox, or black knob wheel at the right side of bike is for decoration...

What I like is idea to use brake disc as wheel hub caps...

Beautifil MOC Johannes

It really looks simple in the most positive way, simple and genious at the same time. Makes me more and tempting to use buggy motor in my moc; but for it I would need some pair of 94.3 tractor tire (from Claas Dominator by @eric trax)

Yes, they look great; specially Dominator 370 with tractor tires that I always needed

ActualIy I was just looking for 94mm tractor tire

Can you share dimension of rear tire on Dominator 370? Thank you in adwance

First of all I wish you fast recevery. With time I have learned that best medicine is natural food...and ironically we both make agricilture MOCs that are characteriatic for pesticide era in agriculture

In this article writes down that max steering angle with reduction hubs are 40°. https://www.newelementary.com/2019/08/lego-technic-review-42099-4x4-x-treme.html?m=1 If this additional info makes sense for you; reduction is 5.4:1

Hubs (and joints) from 42099 set (reduction hubs) have bigger steering angle to ebable smaller turning cycle. They are also much more robust than older hubs (like one from 42054 set) and CV joints that fit in 42054 hubs sometimes tend to fall out under high preasure. Here you can see reduction hub on my front axle solution... So you can use 4 of them at the rear because they are driven in your (future) MOC

Since it is slow wehicle reduction hubs are suggested... Currently (as I could hardly find time for it) I'm working on 1:15 JCB Fastrac 4220 with 2 PF servos (one on each axle) and 2 PF XL motors and planetary hubs from 42099 set. I spent few years to find out how to make motorized multiple steering modes and only compact solution that I came out is with 2 PF servos. Several years ago I was thinki g about Grimme Tectron 415 with tracks (now there are sprockets from CAT and Liebherr) and 750/65R26 ar the rear (perfect for 1:15 scale)

There is also tracked version, but I could not gind if there are possibilities to put one fat (so called flotation) tire instead of two thin (row crop) tire at the front... https://www.potatopro.com/nl/news/2022/dewulf-kwatro-finds-extremely-good-flow?amp

No problem, but you'll need lots of frames to make stiff structure. As I see DeWilf has white rims at the front...but let us be pleasently surprized.

A friendly suggeation )since there are lots of EB members who had an experience with this set) is to post some images here using hosts like flickr, bricksafe... (you upload images and post links to those images max size 1024p), so EuroBricks members could help you.

Looking forward to your choice (and development of course).

Can I ask which one (some "licensed" or generic)? Sounds like Ropa potato harvester ...or Grimme...

@Mr Jos as someone who makes lots if calculations dor my machinery (agriculture, etc...), I can see that one of your choice is to use 750/65R26 tire. Real tire with this dimension is agriculture / forestry tire with 1650mm overall diameter. Reading dimensions in your post gives me one idea for tires if you want to make 100% Lego MOC. If you put 94.8x44 baloon tire inside Claas Xerion (107 x 44 R tire tractor) and put both them on 56mm rim, you will get some 110mm tire which will be cloae to 1:15 scale and 94.8 tire inside will give you more stiffness. I hope this post will be at least little use for your project. Good luck and I wish you plenty of available time.

If I'm allowed to add more data; first technic minifigures were introduced in 1980. https://blog.minifigures.com/bigger-lego-figures-taller-than-four-bricks/#:~:text=Technic figures arrived on the,into the Technic sets perfectly. Minifigure height is 9 bricks (9x9.6mm is 86.4mm let's say...) Average man in europe at that time (in 1980) was 179cm https://www.theglobalist.com/striding-tall-us-vs-ussr/#:~:text=The average height for a,%%2C in one hundred years. Original text: 1.The average height for a male in the United States who was born in 1980 is 179 cm (70.5 inches). In contrast, a man born in the United States one hundred years earlier, in 1880, was 169.5 cm (66.7 inches). 2. That is a difference of 9.5 cm (3.7 inches), or 5.6%, in one hundred years. Finally 1790 /86.4 ~~ 20.7, so @1974 was correct Ole, well done I suppose (due to look of technic minifigure) that first idea was not to present ladies

Some of those? 42178 Space Wheel Loader LT78 (little chance) 42180 Mars Crew Exploration Rover 42181 VTOL Heavy Cargo Spaceship LT81 (could have shocks on landing gear or on cargo compartment opening/closing system Or 42182 1970 Moon Rover

It is always amaizing how you made great Lego models of ugly plastic modern cars.

I like V twin generator.

Yes it looks like 42136 scale, just hope that Lego learned something from "overwhealming" roof solution from 42136. Thanks for the (hyper)link

I still find your Kenworth gorgeus, but I can also say the same thing for this Scania

IMHO (at least) in positive way.
