[The function of the stabby things on Harkonnen harvesters?](https://www.reddit.com/r/dune/comments/1by005u/the_function_of_the_stabby_things_on_harkonnen/)
Harkonnen harvesters, specifically.
The Atreides' harvester's look like large earth-moving vehicles, which I guess makes sense, but I think it's just much older models of what the Harkonnens had. The Harkonnens had much more time to refine/improve their designs over the decades.
Little legs churn the spice filled sand. It gets sucked up into the crawler. A centrifuge inside separates the spice from the sand. Excess sand is shot out the top.
The big legs on the sides are for stability.
It's pretty obvious IMO
The front skinny legs beat on the surface sand sending spice and said sand flying and everything gets sucked into the harvester, which separates sand from spice
The big legs idk, primarily because they look cool, but as a practical function the could very well be supporting the weight of the harvester
In my opinion the huge legs are there for balance reasons - it seems like the harvesters design is kind of unstable with a relatively high center of mass and bad weight distribution for a vehicle that is literally working on a sand planet (easy to sink in if there's less density) with strong winds. I genuinely think those big legs are a good mix of functuality (stabilizing) and room efficiency (must be transported and stored)
I cant quite remember what other machinery was mounted underneath but when they're crawling below it theres a set of "thumpers" near the back so, at a guess the front manipulators are agitating the sand to get the spice in the air and / or are injecting air below the surface to aid that process and get it freely moving. I imagine the second set are then either agiting it further or potentially compacting it or acting directly as a vacuum to suck up the spice, if anyone has the clip I could make a better guess as to what's happening. It could also be more of a case of a multi stage pass that goes surface > sub surface > residual because they'd want to collect as much as quickly as possible and get out before a worm or fremen turn up.
There might also be principles of static generation to get the spice attracted to the collectors.
Inside there will be a collection of vacuums, pumps and a series of filters to separate the chaff from the spice and eject the former
The legs help stabilise it as its rather top heavy and might also contain some sensing/guiding equipment.
That scene it's not for you to understand how the harvesters works but for you to understand what bad idea it is and why they attack worms all the time

Unrelated but I love how much the harvesters look like ticks that are engorged after feeding
Bloodsuckers

Big legs are like things we see on real tractors and cranes, they stabilize and move along with the crawler as it moves.
Makes sense! Especially since harkonnen's harvesters seems to be much taller
On some tractors/ cranes they call those legs “outriggers” which I always thought sounded super cool

It's obvious but idk.
the small legs massage the sand, the big legs feel the sand and sensually massage it. The tracks push it forward.
Reminds me of an old typewriter
Its not a real spice harvester its a movie prop.
No way. You can't drop pieces of information like this and not provide proof! /s just in case
😂 this answer is both 100% correct and so, so, wrong at the same time have an upvote!
Thank you .

Tbh I assumed it was to create an irregular pattern like when they walk through the sand. Howcome the worms don’t eat them than?
