The topic is updated with new video: Hello All! Today I want to present one of my most complex models – Feller-Buncher. It’s the second version because the first one was unworkable and I was started it more than one year ago. The scale is approximately 1:15, model is based on John Deere 900 series Feller-Bunchers with leveling system. I haven't replicated body because I have a lack of green parts. These machines feel trees and stack them for easy removing. At the end of this post you can find the movie with complete demonstration but at first let's see what we have! Dimensions (max/min): 85(71) x 23 x 64(32) cm, total weight – 5870 g, ground clearance – 3.5 cm. Independent remote controlled functions: - moving (four L-motors, left and right tracks are independent). I use old type of tracks for smooth moving; - leveling system (two L-motors with independent control, four degrees of freedom: forward-backward, side-to-side, two diagonals); - tower rotation (two M-motors); - first stage of boom (two L-motors); - second stage of boom (one L-motor); - two-dimension feller head tilting (longitudinal – one L-motor, transversal – one M-motor synchronized with tower rotation speed); - two pairs of claws for productivity improving (two independent micro-motors). Manual functions: - saw blade (micro-motor); - lights (eleven LED pairs). The model has total eighteen motors (two synchronized additional motors are used for switching between modes of operation, because the number of RC functions is greater then number of Power Functions system channels). These motors are powered by seven IR receivers connected to four battery boxes and two accumulators. Let’s see the movie!

It would be ideal to place four of S-bricks here but I don't have them. Thanks for watching!

That's cool! Do you have any photos?

Very interesting shapes! Great work!

Hello! I've filmed a short review of this MOC:

Very nice trolleybus! The doors are awesome!

Hi! I've filmed one more video with this model. I've found cool obstacles at home :)

The next day after competition was very funny too!

Hello all! I’ve decided to create this model less than two weeks ago. I was inspired by trans-orange parts from the 70317 Nexo Knights set and my model is stylized as old very cool series of 1993 year – Ice Planet. The model is 73 cm long. The functions: moving (three buggy-motors powered with two S-Bricks), steering (two M-motors, articulated chassis), suspension (15 supporting sprockets) and plasma accelerators. Video demonstration: To say the truth the external design was my main target so let’s take a look at the photos: Thanks for watching! I hope you like it. What do you think – is it really Ice Planet style? PS: Unfortunately I have no Space sets of 1993 year.

What a beauty!

Very cool bus!

Huge thing!!! Very nice truck. You can transport a cat if you have :)

Thanks for kind words! I think it's not the last MOC in such style :)

Brutal MOD :) Looks awesome in real life!

Thanks :)

Thanks a lot for so many kind words. As for me most of all I like the white cage - it looks really awesome! I have no Friends figs :)))) I have only turtle, hedgehog, penguin and a few rabbits :)

Thanks a lot for your feedback! It's very important for me!

Very nice model!

Very nice! I'll post one more Friends MOC too :)

One more masterpiece! Great work!

Very nice truck!

Great work! What is the purpose of the actuator in the centre of the grabber?

Excellent model! The photos are very nice!

It's a brilliant! Great work!

Thanks a lot!

We have bad weather now :)
