Airflow/dust change with windshield???

I mentioned in my first post here that the wife and I just got our first UTV so we know very little about them, thus my question.

Last night while at a BBQ we were speaking with another UTV owner (Polaris). He mentioned that putting a full windshield on our Teryx would cause more dust to accumulate in the cab than with no windshield at all. He claimed the airflow is changed in such a way that the air curls around and pushes air/dust right into the cab instead of letting it pass right through and out the back.

We thought we might add a windshield to help with the cold air we have here in the high desert during the mornings. Some mornings are near or below freezing even in Summer here at 4300'. I would rather have the cold than extra dust if it comes to a choice. I would hate to spend $400 for a DOt glass windshield only to find out the windshield creates more negative that positive affect for us.

Anyone have knowledge or experience with this issue? True, not true???

Thanks for your comments.

Yep. Its true. Creates like a vortex with air with just a front windshield. I run the super atv flip up windshield (not glass) and you are able to crack it open about 6 inches or so to get air which helps get rid of some dust that swirls back around. I open it all the way up and dust passes through. You can also add a rear windshield or some kind of rear panel and that helps tremendously to stop the dust swirling back around. Also helps keep you warmer too. At least it did on my rzr. I have yet to put one on the Teryx. Ill just keeping eating dust for now.

I have DOT glass W/S....flips open on bottom

rear clear plastic window too......also made some mats to

cover holes in floor...front & rear....soooo very dry & dusty here this year

Just drive like you stole it....dust won't have time to come in..

Good luck buying a DOT glass window for $400..paid $765 for mine

dealer installed when I purchased new '18 in May

inflated $$...probably but was worth the $$ to me

Guys, thanks for the comments. Think we'll hold off on the windshield for now and spend more time on the 'buggy' before we decide about a windshield.

The windshield I was looking at was an EMP, Full, DOT glass at about $450. Comes with a hand operated wiper (law for Oregon).

I run a split windshield in the front and a rear plastic one. Thing is nothing will keep all dust out whether the front is open or closed. I wear a pair of those cheap Wal Mart glasses with foam lined lenses. Just know I'll have a big clean up when I get home.

I run half windshield a few inches up from dash. Keeps wind out of my face but allows enough flow to let dust pass through. When sealed tight to dash, dust would roll in cab and stay.

A rear wind screen/window is a must to help reduce the dust swirling back in the cab. As said you can't prevent it all simply because the sides are wide open......about the same as driving your car down the road with all the windows open. Some sort of flip out or fold out windshield is nice to have but if you have to be DOT approved it limits your choices.

A full windshield sucks dust in, but also (weirdly enough) prevents cool air from circulating into the cab - I know it sounds weird, but I think it's true. My Teryx gets HOT in the cab and I feel like I get zero fresh air no matter how fast I drive... It's the reason why I'm contemplating taking the screen completely off my machine to try out.

Over the 4th my brother and I took a 100 mile loop on some very dry and dusty roads.

Our 2 machines:
I have a 2017 t4 LE with a homemade full windshield with a flip up bottom (see attached link to thread for images https://www.teryxforums.net/members-...eld-build.html).

My brother has a 2016 t4 base model with soft roof and a 13" half windshield.

We both have the tusk soft back window.

I rode the whole time with the bottom portion opened up. I had plenty of airflow despite the fact it was approaching 90F. We did trade off leading and following periodically. At the midway point I couldn't believe how little dust was inside my brother's cab compared to mine not to mention how little dust they had all over themselves compared to us. What I have taken away from this is I think I will only run my full windshield during the cooler wet months and run a half windshield the rest of the time.

Good info., thanks.

I was thinking along the same line..., windshield for Winter and no windshield for Summer.

I think I'm going to pull the full windshield off to see if it improves dust and heat. There are a few people who posted in threads about reducing noise claiming taking the windshield off helps some with noise reduction (maybe it decreases in cab drone / resonation?).

I had a bit of a problem trying to remember my password yesterday so I could not log on with my phone... I wanted to post that Amazon had a "lightning deal" on the Kolpin split windscreen. I picked it up for $187. I wish it would open all the way like the others I see online, but for the price, I thought it was a good deal.

I run a half windshield. Surprising little dust and and it does an amazing job of keeping the wind out of my face. However, I learned it’s useless in the rain.

Our two months of summer has been miserable

finally getting some cooling afternoon T/storms

It does. I rode in 5 degrees last year and you could still feel the heat. It was nice!! I was still layered in some clothes too though.

Anyone have a link to a rear plastic windshield or are you guys fabricating your own?
Thanks,

This is the one I have and very happy with it. It's listed for a T4 but several people say it works fine on a T2.

It is true, even with my half windshield we get dust back. I use the half windshield down until it gets goo cold. I believe you can also purchase a rear dust screen which helps keep the dust back from happening.

I am currently running a full windshield and hard top, the Tusk rear soft screen AND floor mats I cut myself out of some cheap Walmart mats year round and I don't think the heat is any problem at all. Last trip out, I road 140 miles on dusty WV trails (I was lead the entire time ) and was surprised at how little dust I had in the cab. Noisy as all get-out, but otherwise clean and comfortable.

By the same token, I have run the same trails for 80 miles with no rear screen, no floor mats and just the top and 1/4 windshield and choked on dust all day.

And yes, the engine sound bounces off your windshield, top and rear coverings to cause increased noise levels. One way to quiet things down may be to ride "open air" with just a bare ROPS system and nothing else.

Off the subject but (since it's my thread I can hijack it) I am curious, did you do that whole 140-mile trip on one tank of fuel?

No. I stopped for gas at the half-way point. I can go about 100 miles on a tank before I start to get nervous about finding a fuel station. If I know I am going to be out long distance without fuel available, or even if I am not sure, I will carry an extra 5 gallons with me.

The furthest I personally have pushed it without fuel was about 110 miles but I swear I was on fumes!

Thank you, that's the information I was looking for.

I've run my 2019 T4 138 miles on a tank. The gas light was flashing when I got to the gas station. Range really can vary greatly depending on driving style, terrain and lots of other factors. YMMV.. Literally.
