[MOC] Krone BigX 770 forage harvester in 1:17 scale

Recommended Posts

When I presented my first forage harvester Jaguar 900 in 2015, I did not have a specific vision of what my future collection should look like. When I decided that I wanted to build a 1:17 scale model, the model was disassembled and the bricks were used to build the Lexion 760 combine. At the end of last year I decided that I would like to have a forage harvester on my shelf. Then I launched a poll on my Facebook page and asked if I should rebuild the Jaguar or face the Krone BigX 770, its direct competitor. After a year of work, it was created:

The model is a copy of the real Krone BigX 770 machine, i.e. a medium-sized forage harvester, which with the use of various attachments can chop corn or grass to create fodder for cattle.

The forage harvester itself is equipped with seven engines: the XL motor is responsible for the all-wheel drive, and the servo steers the rear axle, which has no suspension due to tighter fenders. The next two medium motors are responsible for controlling the crop throw. Another medium, the motor, operates with a switch that turns on the current for the L motor, located in the intake system, which drives the PTO for attachments. The last medium motor, together with the small linear actuators, lifts the intake system. The model was controlled by three IR receivers. After building an additional attachment, one channel was missing. At the same time, I gave up my earlier plans to create a building manual for this model. So I stopped restricting myself and installed three Sbricks. Thanks to this, I got the ability to control the forage harvester with the PS4 pad and additional channels for LED lighting. I used this type of lights for the first time and I must admit that it gives much more lighting options than the original Lego lights. To keep the work lamps compact, I had to drill a 1x1 plate. It is true that Lego has such elements with a hole in its offer, but not in trans clear color. Sbricks allow you to adjust the light intensity. The whole is powered by a large BBox to get the greatest possible battery capacity. Unfortunately, it was not possible to bring the drive to the shafts in the throat. The problem is practically zero space inside because the L motor is inside

 

As always, I tried to look like a real machine. The combination of Tan and Green colors gave a great effect. The forage harvester has a very distinctive and massive rear. I was able to reproduce the side covers and the entire rear quite well. Everything at strange angles folds into one whole without major gaps. The problem was the front panel with the lights arranged quite strangely in the original. Here I used stickers from set 75954 of the Harry Potter series cut to size with holes made with a punch. The rest of the stickers were cut by me on the plotter. I have a small problem with the roof, specifically its curves. Unfortunately, to better reflect the curvature, I would need elements that do not appear in the TAN color.

EasyFlow 300

 

Initially, the forage harvester was supposed to work only with the EasyFlow 300 tool, which collects the previously mown grass to cut it. The structure itself is quite simple because it consists of a pick-up and scraper rollers. I took the patent for it from my previous square baler model. In order to fit all the mechanisms, I had to extend the whole thing by two studs, which made it seem more massive than the original. Unfortunately, no Lego solution was suitable for the cover, so I used a mosquito net to get a satisfying effect. To keep the shafts stable, I trimmed the axle 32 stud to a 19 stud length. In theory, these could be cut flexes, but their stability at higher revs was questionable and the whole thing is to work without failure for two days of the exhibition.

 

EasyCollect 600-2

 

Although it looks much more epic than the previous one, its structure is more complicated. The six-meter maize collector comes in two configurations, 600-2 folded like mine and 600-3, where the side sections overlap one another. Knowing that the collecting belts will be thicker than the original ones, in this case the folded attachment would reach more than half the cabin and look unnatural. The side sections are folded by medium motors, one per side. Unfortunately they are visible. Initially, I wanted to put them under the side section covers, but found that there was too little space. The belts work very smoothly, thanks to the addition of additional tensioners with rollers, it was possible to eliminate vibrations during operation practically to zero. Earlier, observing the whole thing, one could get epilepsyv :D  I wanted to use black bets with silver horns, but they got lost in their entirety and these elements should be exposed and stand out from the rest. The attachment has most of the original details, such as the handles holding the corn straight to the intake system. An interesting element are the large horns of animals that fit perfectly. Unfortunately, I had to paint them because they are not tan.

 

Finally, I invite you to see the photos and videos. This was the first time I was doing multi-step color grading and using new video recording equipment. I hope you can see the results :)

Beautiful MOC as usual. :wub: I wanted to make similar machine (Claas Jaguar terratrac) but so far I could not figure out how to make both front tracks and rear wheels driven model...

That is just awesome.  It is great to see the techniques which you have used to create your final result.  It can be a bit of a challenge with some of the colour schemes of the krone.  i wonder if this model will make it to CADA....

That is an amazing model! :pir-wub: I am immensely impressed that you managed to make the EasyCollect header fold and function faithfully to the real design! *oh2* The use of tracks and horns for the gathering chains/belts is perfect. Tilting feederhouse, realistic looking feedrolls, a working pickup header - wow. All I'm missing is a cutterhead, with or without a power source. It would just be cool knowing it had one in there. :wink: Really good video to show all the functions and lights, and I love the static shots at the end showing it chopping hay. Brilliant work. :thumbup:

Again a great model that you have made .All the technical funktions are working verry good and smooth.

Great job .

Are you gonne make building instructions for this model ?

I now that he makes the  building instructions for the models from Eric trax ,my son is building the Liebherr dozer for the moment ,alternate for 42100 .

This is beyond amazing! Looks just like it does in Farming Simulator:thumbup:

Oh, and real life as well. :laugh:

O.K. The bar has just been raised. I've seen awesome harvesters made of LEGO but this... this thing is officially the best for me. The colours combo alone instantly attracts you and then you check out the rest and it looks and works so spectacular it makes me wonder (don't get offended now!) do you have a life outside of LEGO? :wink:

No, seriously.. This is perfection!

It's all about the complexity of the model. Even @M_longer perfect instructions won't be able to save customers' frustration when assembling this monster. If we are to take money for something, I would like people to be satisfied. (We are guided by this slogan) :) If there are no building instructions, I would like to share a free stud.io file for the, determined ones will be able to build the model. But first I have to find time.

Yes, I have a normal life! A full-time job, a wife and two pomaranians (dogs). Bricks are not everything :laugh:

 

Thank you for such nice opinions.

I am speechless... watched the video with mouth open....

So smooth and really seems compact, sturdy and oh so functional. Bravo! :wub:

I am quite glad you got the joke. Every word there was mean to praise this work of yours. Keep it up. I'm following you on flickr and I also save pics of your model to my computer. And no, I'm not an obsessive fan, I'm not gonna follow you home or anything. :laugh_hard:
