Any one have any experience with the big boss 570? I'm thinking it would be a great moose hunting machine and I like the fact that it's 2up capable and has a 800 lb cargo rating in the box. I'm currently running a 850xp and it'd done the job admirably so for but my oldest is getting to the age where he'll be tagging along. I'm not interested in a side by side. The 6x6 should be a great work horse. I'm wondering about reliability and rider comfort specifically.
 
no idea but if it's polaris...... be ready to replace Ujoints, axles and cv joints on the regular..... and they come from the factory without grease nipples so they aren;t serviceable/greaseable.
Just watched a friend go thru this with a polaris ranger 570. He orders greasable ujoints from fortnine and the local smithers polaris dealer had a 250.00 aftermarket rear cv axle in stock so he grabbed that instead of a factory replacement.

I'm not a fan of polaris's wheeled machines and seeing how easy it was to blow up a factory CV axle I would want them to upgrade those at the dealer and make sure all ujoints and CV axles are greaseable/

that said..... we blew up the front passenger cv axle and the rear driver side cv axle and that machine still got us home in 6 inches of hardpack slippery snow and mud.
 
The Sportsman 570’s are good machines. In my experience, they are reliable and surprisingly powerful for a 570. The 570 power train has been around since 2014 (I think) and has proven itself to be durable & reliable. I believe the 6x6 comes with the macpherson strut front end? That’s a drawback in my opinion but not a show stopper.

I’m thinking not all people have experienced the same as you. I am still running my original axles and ujoints with about 5800 miles (yes miles) of which about half would’ve been hard miles! Use your noggin and pretty well any machine will treat ya well

Agreed, I had a Sportsman XP 550 that had 400hrs & 5,000km on it when I sold it. Other than suspension bushings and wheel bearings, I didn’t have to do anything to it. It was more reliable than my Honda Rancher.

Haha! I also run a 550xp, I Guess I hadn’t even thought of bushings and wheel bearings. I’m probably due for bushings now, but still on original bearings.
 
Good machines however they don't steer as good when you have the box loaded up. All the extra weight over the back 4 tires makes it want to go straight ahead. Yes you can still get around but you will really notice it.

I wish the rear tag would lock in with the drive on the other axle giving an actual 6 x 6 instead of 4 wheel drive with 6 tires . Maybe they do now ?

As a workhorse and with a reasonable operator, the 6x6 is excellent. Much more float, much more traction, and much more hauling capacity. Much less getting stuck. They smooth out the ride noticeably as well.

The tradeoff is that they are not as quick or as maneuverable as smaller machines. And they take up more space in a truck box or on a trailer, obviously.

We've always been very happy to have one at moose camp. No particular issues observed, unless you're getting an older model with chain drive (watch the chain tension).

a 68 year old man who looks after his stuff owns and was driving the machine. I'm guessing mileage similar to yours. Mind you the country where here lives is some pretty rough terrain in north western bc. Sub zero and a fresh foot and a 1/2 of snow fell the night before I drove home and the week before that it was mud city LOL
still doesn't excuse the fact that the factory ujoints and cv axles were ungreaseable. I would check for that and ask for an upgrade in the original purchase agreement but that's just me.
 
I have the older 500 BigBoss with the chain rear drive. Axle shafts in the front. I like the box carrying capacity. The smoothness, and the traction- flotation over the ugly stuff.
 
Just bought one this year.

Hasnt been stuck yet.

Will float over alot more soft stuff.

As mentioned not as maneuverable as 4 tires.

I am VERY happy with it so far.

I have a 15 Ranger 3800 miles.

Did a couple u-joints, and 4 wheel bearings other than that its been pretty reliable.

There is an wheel bearing greaser you can buy online that you dont have to remove wheel bearing....just castle nut....slide the sleeve in....and grease the bearings.

All bearing manufacturers seem to be racing to the bottom with cheap grease or no grease from factory.....

Dont think this is limited to just Polaris.
 
Have a 2003 arctic cat and none of the bushings are greasable, most are still original. Picked up a new sportsman 570 a month ago after ordering and a 7-8week wait, runs well. Time will tell if it's as reliable as my 2010 sportsman 850xp esp, it's the workhorse of our little farm and apart from some suspension parts here and there it's been a great machine. I didn't hesitate getting another Polaris.
 
My Polaris 570 Ranger has over 12,000 kms on it. First repair to date is Right rear wheel bearing @ 12, 339 kms.
And this was only because when changing a rear tire I noticed a slight amount of play in the hub.
 
I have a 6x6 500 chain drive and Iam not a Polaris fan to begin with. I like box carrying capacity(I have put spiker elk in it gutted) and gets used lots around the yard due to high maintenance of the chain system when used hard. The shaft system would be much better and I like the engine size with the new ones. I wouldn’t touch a 800cc engine model. I find the front to be heavy on mine but does seem to push through when asked to. Only thing is that they are long and take little to turn around in tight corners or trying to turn around
 
I have the 800 motor from 2010. It is absolutely the fastest return on investment machine I've ever purchased.

Its used daily and 4000 hard miles on mine. As mentioned you will need power steering and to keep an eye on axle boots but they are easy to change once you do them a few times. I keep a few in hand to change as needed if a stick rips one or one wears out.

Mine has hauled several moose and often whole without quartering if it's a small one. One time I even had 3 grown men and a calf moose on mine and it went through some country that would make mud bogging look easy.

Only downside I see has already been mentioned- it'll be hard on the tailgate if you're putting it in a truck box.

That 570 is a good motor you won't be disappointed.
 
I worked on a few Rangers at work.. Yes I replaced A arm bushings, axles, shocks and tie rods a bit. But guess depends on how hard you are with them.
