[WIP] Herder One

nick97 · April 23, 2020

Hey all,

As I mentioned in this topic some time ago, I'm currently building a Herder One. And now it is time to give it its own topic.

Some info about Herder first.
Herder is a dutch company specialized in ditch cleaning. They have a range of different mowing arms and attachments for cleaning ditches, but they also produce flail mowers en stumpcutters. As attaching mowing arms to standard tractors is becoming more difficult, Herder developed a vehicle with a mowing arm already attached. As the vehicle is build around the mowing arm, it is for example better balanced than a tractor and has a better view to the arm. The vehicle Herder developed is called: Herder One.

A few years ago I read about it in a magazine, where they showed the prototype for the first time. I've read the article over and over and took a very close look to the pictures as this was the only information avaible at that time.

About the vehicle:
The Herder one has four wheel drive and three steering modes: front, four wheel and crab. Suspension only on the front axle. Front hydrolics for attaching a mower and a rear hitch for attaching a trailer. Cabin rotates for better view on the ditchmower.

The Lego version:
My Lego version is scaled approx 1:16. It also has four wheel drive and three steering modes, all controlled using an S-brick.The first version had suspension on the front axle, like the real machine, but it takes a lot of space in the chassis and it made the chassis a bit weak. Therefore the second version doesn't have front suspension. Also present is front hydrolics and cabin rotation, both manually. Rotating the mowing arm using the S-brick. Controlling the arm is done manually, pneumatic switches are under the hood. Pneumatic pump is motorized.

Pictures:
The next pictures shows the second verison without the motors for the arm and pump. In the back (left) the remains of the first version.

Next pictures with the motors:

The other side already has the turntable for the mowing arm

And some pictures of the first version:

And what it looked like a few days ago:

Hope you like it, comments are welcome :thumbup:

I want to and this post whit a question. In the first verion I used pneumatic hose from some original Lego sets, none of them were cut to fit. For this second verion I need to to buy hoses so I can cut them in the right size to fit the model perfectly. I do prefer to have them in dark grey, like the older ones from Lego, as these would look better on this model than the newer shiny black ones from Lego. So can anyone help me finding good hoses that aren't to expensive?
