Week TechVideo, 2012 #46 - Feller Buncher

Nowadays we see that everybody builds motorized Technic machines with plenty of PF elements, while the smaller models with manual functions seem to have become almost an exclusive from TLG LEGO Technic Designers.

Thus it was a pleasantly surprise to see a model today, from Kyle (Thirdwigg) who built a mini Wheel Feller Buncher [1] with a few manual functions. Still I dare to say that apart one or another aesthetic detail, this could perfectly have been a small/mid size official LEGO Technic set.

Regardless the frustration denoted by Kyle at his website (Thirdwigg.com) in achieving the maximum number of functions and having to leave something behind after all, I think the result is pretty good and of course there are always some compromises we must face, when working at smaller scales.

A Feller Buncher is a type of harvester used in logging. It is a motorized vehicle with an attachment that can rapidly cut and gather several trees before felling them. Kyle's model looks very similar to this CAT 553C and you can see it action from the video below.

This model features a very decent set of functions for its size:

• Steering via HOG
• Functional cutting blade
• Functional grabbing arms
• Lifting arm

As the original idea was to isolated the lifting and tilting movements, it just missed the tilt feature that would allow the elevation to happen while keeping the feller blade parallel to the ground.

You can find the full gallery of photos and instructions, from Kevin's Brickshelf folder.


Awesome small model with manual functions. It has become rare!

Please avoid sending requests to post specific models on this TBs section.
We understand some of you would enjoy to see your creations featured here, but please understand  that because only one video gets highlighted per week, it is impossible to accommodate all the great MOCs continuously build by the Technic builders out there. They simply won't fit all and that's also not the purpose of this blog (see the header statement).
Many of your MOCs are scanned anyway and listed for later publication when they do not fit immediately. However some remain in the backlog queue just for too long and eventually loose the relevance or the publication opportunity window. As a rule of thumb, we also avoid publishing MOCs that have been featured by their authors or other fans at some other great web places dedicated to the Technic community out there. It doesn't mean that occasionally some won't get published here anyway.

Thanks for your understanding!
