What the gear levers do on a U411/U404

A) Main gear lever
- 6 speed
- 2 working gears, 4 road gears

1 & 2 are usually only used in the fields and for reversing etc,
3,4,5 & 6 are the road gears.
Between the working gears and the road gears there is a gate
that you need to tap the gear stick over to get to that set of
gears.
B) Forward and reverse
- forward, neutral, and reverse
In order to get into reverse the main gear stick must be all the
way over to the left (1st and 2nd area)
All the way forward is forward
middle is neutral
all the way back is reverse
C) Low gears
Move this lever over to the right to go into the lower gears,
then use the main gear lever as usual.
usually used when working with implements etc.
an option from the factory was an even lower set of gears
operated by the same lever, as i have never operated this myself
i will not try to explain how it is operated.
D)2x4 4x4 diff locks
- all the way down = 2 wheel drive
- Half way up = 4 wheel drive with gear box diff lock
- all the way up = front and rear axle diff locks
E)PTO
PTO (power take off) is used for running implements on the front
and rear of the vehicle.
- pull the lever up to power both PTO's
only both PTO's can be run at the same time.
F)Hand Brake
- squeeze handle together and pull up to engage or lower to
release.
ALL THE ABOVE MUST BE ENGAGED WITH THE CLUTCH DIPPED, EXCLUDING
2X2, 4X4, DIFF LOCKS AND HAND BRAKE.
G)Diff lock oil
remove cap and fill with ATF oil, replace cap.
Some models had rod or air operated diff locks, please check
before commencing
H) Gear stick grease
A blend of a little ep 80/90 and a blob of grease.
Please note that through the generations of the Unimog Mercedes
made several small changes to several things, please be certain
that this is the correct gear box for your vehicle.

Very handy bit of information here. It took me a while to work
out what type of oil to put into the diff lock reservoir.
What can you tell us about the crawler gear lever that I see on
this photo. I heard that the pto gearbox has an effect on the
gear lever position for the crawler gearbox.

Hi 411mog, welcome to the club :)
i have never heard of the pto having an effect, but the
forward/reverse lever does. when engaging the crawler gear box
the "neutral" position on the forward/reverse lever acts as the
forward position, as soon as it is knocked all the way forward
it comes out of crawler box.hence, to engage crawler box, the
forward/reverse lever has to be in neutral, or reverse :) sorry,
i should have put that in the tutorial in the first place.

HI
I'm a bit confused. Does that mean that there is no option of
having the gear box diff-lock and rear axle diff-lock engaged
without the front diff-lock engaged?
Cheers
Mick

do you mean can you engage the front and rear diff locks
separately?

Yes, there are many times that the lack of steering with front
diff locked would be a disadvantage.

true, it can be a disadvantage, but on the 406's and later it
can be easily modified as they are air operated, so it only
requires a switch to engage the front and rear difflock
separately :)
However, it would surprise me if mercedes didnt have a reason
for making it like this, as its such a simple thing to do.

Think I would like them controlled separately, the only reason I
have ever heard for a similar set up was; if you are stuck
you're not going round any corners.

Hello everyone. I am trying to figure out the gear lever scheme
for a U411. Can anyone post the pictures with a clear view of
them? since at this moment the pictures are blured, and the
content is not well visible. Thank you very much!
