I know when I bought this bike from my Dealer he had a lot to say about these 3 items and how they were add-ons for the 07 but now standard on a lot of the 08's.

I looked around and couldn't really find any discussion on this, maybe I just don't know how to use the search function yet.

Anyway, since this is my first Quad and after reading some of the posts here I made some observations if nothing else to start a discussion. Maybe some others especially 800 people can chime in.

I don't believe I have any problems just general observations.

ADC or Auto Descent Control - Dealer described it as keeping the front locked in rather than allowing the front end to freewheel going down hills.

EBS or Engine Braking System - Dealer describe this as how Polaris uses the transmission and the engine to essentially "Downshift" the bike using engine compression to control or slow down the bike

AWD - All Wheel Drive - Described as the switch that engages the front differential so you have all 4 wheels going forward and reverse if I pushed the yellow button.

So here is what I notice using these.
AWD engaged descending a fairly steep hill the bike will slow to a crawl unless I push the gas then it speeds up, release and it slows back down.

AWD engaged on the flat - excellent takeoff, no real roosters unless all 4 break loose. From about 20 mph or so, the bike decelerates very quickly, about half the distance of no AWD, I assume this is the ADC and EBS kicking in.

AWD disengaged descending same hill, Bike seems to descend a little faster but there are no traction issues so hard to compare.

AWD disengaged on the flat - Take off is good can either pull front wheels up or even rooster with enough throttle (FUN) but anyway From that same 20 mph or so, the bike decelerates good, but the distance seems about 2x the above with having AWD engaged. As I remember from Dealer ADC only works with AWD engaged. The biggest thing I notice is the run is the same distance for the test, and I find myself engaging the brake to slow enough for the turn at the end.

Now the one last thing. Sitting at a stop when I engaged AWD switch I hear a slight click and dash indicator comes on. When I make a Run In AWD and come to a stop, once stopped if I disengage the AWD switch, I hear a click and the big seems to unload the front end slightly and it raises a half inch or so.

This all seems normal. What are your thoughts or observations?

Does yours work similar?

TIA

 

adc=active descent control
came out on the deleux models in 07' when you switch to awd/adc when under 15 mph in high or low range and no thorttle given it locks the front end in to add to the ebs braking but totally sepreate. the ebs is the primary clutch which has a one way bushing that slows the belt down when the throttle is not on. it does work fairly well on hills for sure. dont try to do wheelies while in awd so there will there chance of braking the roller cage in the front end.

 

Sounds to be working! You'll really notice the ADC when you go down a very steep trail, without ADC the rear tires will slide and be hard to control and with ADC it'll just slowly crawl down!

 

But don't tackle the really steep short drops(70-85 degrees) in AWD or the front end will grab and flip you over the front, almost happened , back wheel lifted, go 2x4 and give it gas. And don't tackle the really steep LONG drops at all.

 

Also, I thought you are NOT supposed to engage AWD unless
you are slipping? WIll this do tranny/clutch damage or clutch
belt or something else? Just thinking when this is done frequently or
HARD, like above testing the difference between IN AWD or OUT of
AWD.

Never engage AWD if your rear tires are spinning you will break your front diff!

You can engage on the fly as long as the front and rear wheels are turning at the same speed.

 

RickCj7,

I think what I meant to say is that
when all the tires are spinning or slipping
that is when a person should be using
AWD or 4x4 (Not indicating switch from
2 mode to 4 mode while in action, no no,
I can see how that my post was misleading)

Anotherwards, ya shouldn't run AWD on dry
ground only when you sense wheels are slippy
etc. Now how you enage it, is what you are
pointing out. Stop and switch to AWD mode when
you think you are stuck in that scenerio.

Cheers,

R'

 

Yea I kinda figured it was similar to my Ranger 4x4. If it doesn't need 4x4 don't use it.
I tend to live by the rule, 4x4 is for getting unstuck only..

Anyway, since the bike is new and my first one, and I couldn't see any posts about normal operation I wanted to place out here my observations. I assumed it was normal. If nothing else maybe it can help someone else.

My field is just starting to dry out, so mostly I am in 2x4. but my hills are still pretty sloppy and enough of a grade I still use AWD so I don't rut them.

It really is a sweet machine. Got about 50 miles and 34 hrs on it at this point. Most of which has been moving snow, and now some rotting feedbeds etc.
But then every couple days I take it up to the back property I got some fencing to get started up there as soon as ground dries a bit.

 

Heck no, you can ride around all day in AWD it only locks the front when needed!

 

For people who like to ride without every worrying about what mode to use, put it in AWD and leave it there, in won't "harm" anything.

But for those of us who like to actually "control" what our machines are doing, 2X4 is there for when we know we don't or won't need AWD.

Besides, on the '07 equipped with ADC, keeping it in AWD all the time will cause accelerated wear on the ADC components and/or front differential. The '08 ADC equipped models come with a switch to have AWD without ADC.

I currently have ADC disconnected, and will soon have a switch wired up in the pod so I can turn it on only when I want or need it. I have the switch installed in the pod, I just don't have the wiring part of it done. I'll still post some pics on that project once its completed.
