Forgot to add the plow is winch operated and she usually starts right back up no problem after stalling.

 

Mine has done it brand new and still does with 130 miles. Happens with light taps on the throttle. I haven't really found an answer.

Never heard of it and I have seen some videos of 570's pushing pretty good amounts of snow. Does it seem to stall out when it gets too much of a snow load or does it seem to be related with something you do with the throttle?

 

Mines like this and it seems about the same way others stall aswell. Happens towards the end, you can hear me tappin on the throttle.https://youtu.be/rP2WZiUI8fg

Take it back in to the dealer...... utilize the warranty!!

 

Mine stalls at least a couple of times while plowing too. I think it has to do with the battery power, but I could be wrong.
Always starts back up.

 

Let go of the throttle before it begins to slow down at the bank. It should reach idle before you come to a complete stop, else it will stall. Treat it like a standard in that regards. Think about it, with rpm up belt is engaged. There is no torque converter in this.

 

Bike shouldn't stall. Let go of gas and should instantly go to idle.

 

make sure it isn't your keychain who get stuck

 

Mine did the same thing, hard push into a bank, hard on the throttle, as soon as it starts to slow down, release the throttle...stall; restarts right away. After dozens of these occasions, I started to notice things...

battery - I have a hardwired volt meter running all the time, battery voltage just fine; even after plowing for an hour. Not a battery issue in my case
Method - I backed off a bit on the throttle before hitting the bank, that improved things but still stalled once and awhile
Gas - I was running the same gas the dealer had in it, who knows how long it was sitting. I ran it down to 1/3 and filled it up with new gas...new gas and new method; no stalls, in the last 3 plow sessions (each around 1-2 hours).

My guess, only a guess, is that its a bug in the fuel curve in the computer and maybe in combination with the EBS. My reasoning is that hitting the bank (everything is slowing, and heating up) is indicating to the computer that it should back off the injector pulses, at the same time I'm lifting the throttle input, an addition requirement to back off the injector pulses - one of the two is adjusted for too quickly/radically and the engine fuel is instantly cut off. Makes sense in my tiny engineering trained mind since when it stalls, it doesn't sputter or wind down, it just quits instantly. The other thing to note it that it starts right up, no winding and sputtering; starts instantly. The stoping instantly indicates no fuel, the starting so easily also indicates there isn't any wasted fuel in the engine (no signs of flooding or partial flooding when it starts).

I'm going with a combination of crappy dealer gas and a bug in the computer fuel curve. Good gas and by slightly altering my plowing style, I get good results...

That being said, it sucks that I can't take this thing full on into a snow pile and not worry about whether or not its going to stall out at the end.

You are over-thinking it.

It's just the clutch still engaged with engine RPM above idle when the bike hits a resistance that slows the bike to a dead stop, with too much friction against wheels to keep spinning at suck low speed. Hence.. motor stalls. Same thing happens if you accidentally let go too late going over logs.

The same exact problem happens with plow trucks that have standard transmissions or torque converters that lock in 1st (rare)

For those that do have battery problems keeping up with the plow... thats a different story. My battery is pretty weak as of lately.. so what I do is i only move the winch when throttle is applied. It takes a bit of practice finding a good groove ballancing throttle, winch, clutch position and rpm but once you do, bike will NEVER stall.

 

This is not a standard transmission. This doesn't have a torque converter. As soon as the gas is released the clutch should release the belt. No stalling. Not normal!

 

Unless a clutch can disengage within a split second (which it cannot), it will stall if it comes to a complete stop against a snow bank before it disengages. It's basic mechanics. The engine rpm cannot go from whatever to 1250 in 0.111 seconds. It just cannot. Even if it could, by some miracle, the clutch still has a delay, too, due to centrifugal force.

 

It can, and does disengage in a split second. If it doesn't then there is a problem!

 

its not possible under load. there's always friction. But, beleive what you will. Guess about 60 million atvs worldwide dont have working clutches, then

 

try the follow procedure,
if you drive in a pile bring the ATV with the brake and not with the snow to a stop,
i am pretty sure this will avoid the stalling and in the same time the hard shifting,it takes a while to get use to but it works.

 

It should never stall. If it starts right back up then your battery should be good enough.

 

Well, plowed 3 driveways on Sunday and it only happened one time. When it stalls, the dash still has power so maybe not a battery issue. The dealer hasn't heard of this problem so Ill print up all of your recommendations on this thread and hopefully we can figure something out. Thanks for all of your help guys.

 

My 2016 is doing the same thing. Today the dash started giving me a low battery warning, then it would stall and I wouldn't be able to start it for a minute or two just like a weak battery. After sitting for a couple of mins it starts right up no problem.

 

Same here ,2017 570 . stalls every 4 or 5 times I push a snow bank hard and starts up really hard after. Dealer says they" never heard of it " told me to adjust the throttle cable . even though it had 5 miles on the odometer when this bullshit started. So I tried to adjust the cable as they claimed the cable must be stretched @ FIVE MILES. Of course they was nothing to adjust , no slack in the cable. Now the dealer wants me to leave it with them for a couple days. I'm not dropping my plow rig off in the middle winter. Is anyone else making progress ?

 

try this,if you hit the snowbank go slowly of the throttle,don't just take the thumb off

 

Btw , no low voltage warning for me , its Not a fuel issue , sits in a heated garage .

 

I have a new 2017 570 with the Glacier II plow system and it hasn't stalled once yet. I'm moving massive amounts of snow as well. I do manipulate the throttle a lot. That could be the difference.

 

Tried that too , stalls with thumb still on throttle. Stupid shit to deal with on a new machine.

 

Funny part is how so many complaints of these things stalling in various conditions through out various years. Dealer " never heard of it " . Gonna buy a shovel next time.

 

Mine used to randomly shut off. The throttle safety switch was the problem. Try defeating the switch and see if it stops doing it. I have mine defeated permanently.

 

Awesome ! I hate that safety bullshit. I'm sure it's related . The impact of hitting the snow bank must be activating the safety nanny at the earth shattering 5 MPH . Its the best theory yet. Thanks I'll check it out .

 

had this issue with the 400 ho once cable was adjusted correctly never happened again but I will remember this vid.

 

Reading the issues owners are having, really, should a person have to do it a certain way. What happened to the old days of you hit the throttle and it works. There shouldnt have to be a "certain way" to use the quad so this doesnt happen.

Its like loaning something to someone and having to explain how to use it a certain way for it to work, whe it should just work the way it was designed to

 

I was surprised this was an issue at all. I'm with Spidey. Just googling polaris and stalling resulted in pages spanning years. Stupid problem to have. This 2017 Polaris replaced my 2007 Grizzly 450. Only sold it because I didn't need it at the time. Should have never let it go.
