UTV's and ATV's general discussion.

This battery BS is derailing an otherwise nice thread (and I regret contributing to it, though I did try to relate information without attacking anyone.)

I respectfully suggest we all give it a rest and discontinues the pissing match... or start a new thread to debate how temperature affects battery capacity.

Some of the Polaris models used to freewheel below a certain speed so the “trick” was to touch the gas to keep the RPMs up and keep the engine brake engaged.

Yeah, it was avoiding exactly that that made me cross the Polaris line off my list. Such a counter-intuitive driving mode: "I need to go slower, so I'll step on the gas" is just not a natural reaction when I'm putting along down a hill and the driveline suddenly shifts into freewheel. I wanted something more predictable in it's response. I could eventually get used to it myself, but I'm not the only one driving my machines.

Glad to hear Polaris is at least offering an option that addresses this. @deserteagle71 , do you know if they offer it on all models, or is it just an option on their higher end machines?

I've got two antique Coot ATVs that do that. They originally shipped with a Tecumseh engine that idled around 800 RPM, so the comet clutches were set to engage somewhere around 1000 RPM. I bought one of them where the previous owner had replaced the drive part of the clutch/CVT system with one from a snowmobile of a similar era. It looked the same, but it was set up to engage up around 1800 RPM. The brake system is weak on these units. I got quite a surprise when I took it out for a spin and the clutch released at half speed, rather than close to idle. Fortunately, the worm gear drive system still provided a bit of drag. I did still smack a tree when it first let go on a steep, winding section of trail.

I have a 2018 Polaris Ranger XP1000, it came stock with the EBS, and you do not have to step on the gas to engage the braking, you only have to lift your foot and it slows down very quickly. I do see on the Ranger 570, that EBS is not provided and would be an option. It appears to be a standard feature on the higher end models.

I don't know just which models have it and which don't. Our new Ranger XP1000 the County bought for our Search and Rescue unit does not. I subscribe to a UTV magazine that regularly tests all kinds of side by sides and quads and they regularly talk about the lack of engine braking in various Polaris units...also how they don't have actual 4wd, only AWD which only activates the front drivetrain if the rear wheels are turning faster (spinning) than the front. Here is an excerpt from a test they just did on a fancy new RZR 1000:

John, I have almost bought 2-3 coots over the years. Last one had a small diesel conversion that made you slightly nauseous due to vibration

They are fun, quirky little vehicles. And you can really freak a passenger out by driving it into a pond: It just does not look like an amphibious ATV.

Ya, stuck with the Rokon, Quadractors and trikes

I got enough issues

Intercoolers are used on turbocharged or supercharged engines because the compressed air rises in temperature. Cool it a bit and once again one can get more air mass in the combustion chamber.

Actually, intercoolers are used between two power adders, be they turbos or superchargers, but usually its a turbo followed by a supercharger.

Bottom line, as the name strongly suggests, an intercooler goes between the two. Otherwise it's a charge air cooler.

Did you post about your Quadractor on here before? Ever since I was a kid. I thought they were incredibly interesting.

Where are you from? I'd love to see your collection, if I'm ever in your area.

I’m sure I did!

I have not heard the name. I'm afraid to go look. If I come home with any more gadgets, I'll probably end up single.

Clearly you have not mastered “I’ve owned that for 10 years” speech!

 

[Grumpycat]

nice to see you admit the facts

Golly, you have a hard time with reading comprehension as I have never denied fact.

However I will challenge any who makes unfounded claims such as, "Eggs are yucky" without any further details such as, what kind of egg and how was it prepared?

we got ask to let this go...

post 462 imply you denied it.... I get your point, not all battery or vehicle are made equal, but my point is simply all battery gets affected by the cold its physics, you simply seem to deny that until you didn't.

Do one need to eat sh%t to know how sh%t taste like? but SH%t from what kind of animal ? humans, cow, horse, dogs, or cat ? I agree some SH%t smell worse then others but sh%t is Sh%t.

If one need to try everything for themselves and not take anyone word for it despite how many say it to know what works and what doesn't he/she must have a very slow learning curve...

“However I will challenge any who makes unfounded claims such as, "Eggs are yucky" without any further details such as, what kind of egg and how was it prepared?”

I hear that there are some new “fact checker” positions that may have just became available. Maybe this could serve as your resume?

As the Beatles sang “Let it go….”


Anyway back to the Q. 5hp motor, can skid about a 3kLb log. The log underneath generates the traction via weight transfer. 72:1 reduction. 4wd and 4 wheel steer via all belts and cables. Also has plow and 3 pt hitch

Are both your coots 4ws? I hear they are otherwise slow to turn?

My first one was a 2 wheel steering, but I had it converted to a 4WS. (A guy in Maine who had done the conversion on his own Coot used mine as the vehicle to develop a kit with instructions for the conversion. I later retrofitted a 16 HP Briggs Vanguard V-twin engine in place of the Tecumseh, which had become unreliable.)

My second Coot was 4WS when I bought it, and had already been converted to an 18 HP Vanguard engine.

All Coots are full-time 4WD. They have no differentials: each axle is driven by a worm gear set up, so all 4 wheels turn at exactly the same speed all the time. That combined with a smooth belly with 12" of ground clearance means they rarely got stuck (even with the original 8.85-15 NDT military jeep type tires - which I think frankly suck for traction.) About the only thing that stops it is getting high-centered or sinking into mud so deep the wheels have no traction. When high centered, it's usually easy to fix: shift the weight so at lest one wheel has traction, and the smooth belly will usually slide off the obstruction. Since the front and rear tubs are articulated, the body can pivot, making it easy to keep all four wheels on the ground in most situations. This picture gives you an idea of the articulation (the Coot has since had a roll bar added. It still needs a new paint job - don't know if I'll ever get around to that. This is my "work-in-the-woods" Coot. The new tires I had just put on just prior to this picture are definitely overkill.)

The original 2WS Coots had a huge turning radius. With no differentials, and all wheels turning exactly the same it tended to scrub in the turns and just want to plow ahead. People used to joke about needing an acre of land to turn around, or needing to make 14-point turns to turn around on their trails. A few years into the production run, Coot started offering a 4WS option. It definitely improved the cornering, and Coots with that option fetch a higher price on the market today. They are still not as easily maneuverable as a modern ATV, but they will go places most ATVs couldn't come close to (a tracked ATV might go most places, but the Coot loses them when you drive into the pond and float across.)

My Tuatara beats my previous Yamaha Rhino 660 every way you look at it.
But they are not silent, just very much quieter. You can hold a conversation at any speed.
Very expensive, too.
And, yes, 50 mile (very short) range. And max 25 mph.
Fine for me in Southern California. I never go over 12 miles in a day.

That is a solid-looking trailer. No info about it on their website.

And no pricing.

I see 30 mile range listed on the website.

Post 462 says nothing like your interpretation.

You claimed specific cold temperature range losses with no citation of sources, or even knowing what battery was in use. And without citing temperatures.
