Could someone explain the difference to me?

[rapracing]

I see posts about the RTV not being a 4 wheel drive and others actually are. I know the RTV states it is 4 wheel drive but apparently there are differences in it and the other machines.

I am really leaning toward the RTV. My wife has horses and I like the idea of the hydraulic dump for her to use. It would be difficult for here to dump 5 or 6 hundred pounds of poop and sawdust by hand from the others. I know the Ranger has an electric dump option at about $500 bringing it up to the price of the RTV and it just appears the RTV is built much more solid. I will use the machine to get wood out of the woods and we live on steep terrain so if there is snow I want to be sure it is going to go also. It will also be used for hunting and some leisure riding. However speed is not important.

Thanks for the input.

You can add a hydraulic dump to the John Deere gators.
Shouldn't be a big deal to add it to any utv with a bed.

The RTV is one of the only utv's that hasn't went all wheel drive.
It has a limited slip front differential..

On a positive note, the RTV has the nicest instrument panel and cab of any utv I have seen..

 

[rapracing]

So I guess that means that only one of the front wheels pull at any given time?

If I am not mistaken both rear wheels can be locked in?

 

[Skipholiday]

Correct. The rear wheels fully lock.
Both fronts will spin until they get in a bind. The binding wheel will not pull.

So I guess that means that only one of the front wheels pull at any given time?

If I am not mistaken both rear wheels can be locked in?

If you get the RTV put a set of 589 tires on it. Makes all the difference in the world. Will go practically anywhere.

Will these tires tear up a yard? I know the RTV has limited slip, but I think those aggressive tires may leave a mark. We've had a lot of rain over the last few weeks. My pastures are a wreck and the red clay is slicker than snail snot. I like the worksite tires for general purpose work, but I had to go into about 8 inches of wet horse poop tonight on a serious incline and under load. The tires quickly became racing slicks (no visible tread), and I had to put the vehicle in four wheel drive to get out. I don't think I would have had to do that with better tires. Plus, when you spray the worksite tires with a hose, they spit back at you.

JD Gator XUV has "True 4wd" which means whichever (or both) front wheels with traction will pull. But, it's an on demand system so it will not scuff turf even if you leave it in 4wd. Hydraulic dump system as well.

I've got you one in there !!!!

with the right tires you don't need true 4 wheel drive.it never slowed my 04 hpx down from going through the mud holes.now with stock 489 tires you have aproblem but with any stock tire you ain't going through much of anything. put some 589's on it and you'll be amazed.

The 589's are very aggressive, really not suitable for the lawn. I plan to keep the 589's on from late fall to early spring and then switch back to the worksites for the drier months.

here is a quote from a good article Deerlope linked me to..
How a differential locker works...

With a standard open differential (found in 4WD vehicles).... If one of the four wheels loses traction, lets say the right rear, the rear differential senses this as less resistance and makes that wheel spin. A spinning wheel does not move the vehicle. The other wheel on the same axle (on firm ground with plenty of traction) gets the same amount of torque as the spinning wheel. Not much. Both wheels together do not produce enough torque to move the car. A differential always distributes torque equally. The amount of torque generated at the wheel with the least traction determines how much the other wheel will get - the same amount of very little. Little torque because traction is low at the spinning wheel.

Should the right rear wheel have lost traction due to a height difference on the trail or some slippery situation as snow or mud, the left front wheel will also lose traction and spin even though the ground under the front axle is level. This diagonal wheel spin is very common. So, the right rear and left front wheels are spinning. Bottom line...YOU ARE STUCK!

(This is what the RTV has)
Limited Slip Differentials, the name says it all, they limit wheel slip. They do not prevent wheel slip. They only limit wheel slip. Traction is lost later than without limited slip. Looked at another way, you will be stuck a little later. Traction will be lost when more torque is needed to move the car. Limited slip creates additional resistance and allows for a higher torque value to be produced at the wheel with less resistance. Even though LSD is a help in light duty situations it truly doesn't do anything when the offroading goes beyond a standard flat dirt road.

Fancy names like Trac-Loc are not differential locks - they are disguises for limited slip differentials.

(This is what true 4 wheel drive vehicles have)
Differential Lockers or diff locks are the only cure for the known shortcoming of differentials sometimes not distributing enough torque to the wheels as described above. Diff locks disable the differential's ability to sense resistance. By disabling (locking) the differential it is forced to send equal amounts of torque to the left and to the right wheel. This guarantees that any wheel with traction will receive torque to move the car.


Diff locks will make the difference between STUCK and still DRIVING.

sorry skip your getting the wrong info.

What info is wrong? Please quote something I stated that is incorrect..
The information I posted was from a link that Deerlope sent me via pm.
Here is the exact link.
I'm glad your hpx does so well. My 05 hpx was fun, but it didn't go the places that my 06 hpx would.
And my 06 xuv goes places my 06 hpx wouldn't.
The rear end hanging down lower than the axle in the rear kept me off many trails with the 05.

Every ones riding conditions and styles aren't the same.
We do more than mud ride. We hit the hills and the rocks.

Show some video's of your hpx doing something difficult..

there is your misguided proof i have been in plenty of mud hole where my front tires have drug the back through. what you posted is saying that they will not even produce enough tourque to move a car. thats wrong! you posted a videos of the xuv climbing a hill but cut out the video of it getting stuck on a little rut at the top.my hpx would have done that in 2 wheel drive.i showed you a picture with my hpx loaded it don't squatload the xuv or do you want me to put more weight in it for you? i shall get you a video of a good mud ride and prove it to you that lsd don't matter if you mave the right tires and know how to drive .

 

[Skipholiday]

LMAO now thats funny..

I never cut any video. All my vids are posted on my youtube site.
The one the 06 hpx getting stuck on the root is on the 2nd page.(They get moved as I add more..)

And it was stuck because of the rear diff guard catching the root.
Thats why I traded for something better.
I have four 4 wheel drive vehicles. 2 are true 4 wheel drive and 2 are lsd.

1st hand experience with both types proves to me which will go better.
Thats a no-brainer..

 

[TOMMYHPX4X4]

i sure didn't see any rut big enough in that video to hang up on the rear end. it just looked like the rear tires was spinning and the video was cut off! if it was hung up on the rearend then why was it sliding to the side ??if it was hung up on the tranny it would have stayed put all he did was nose up to a root and spin the tires thats all and agian the right tires and driver would have takin that "little hill"easily them mud-lites are just for lite mudding.

 

[RollTideRam]

Tommy, he said it was stuck on a ROOT, Not Rut. They are different. Until you ride somewhere besides a mud hole, you will not understand what Skip is telling you. If you are happy with what you have, good. Other people ride others places that require additional traction. Not the same, but I have driven my Samurai stock with open diffs, then added a mini spool to the rear (3 wheel drive) then added a locker to the front. I can go more places now and I don't have to drive the snot out it to get up the same places now. JC

 

[TOMMYHPX4X4]

sorry i ment to say root. but what skip has posted is saying the front tires do not pull what so ever and that is not true.he keeps popping up with the 3 wheel drive thing and how you can't go no where with it and how it's not good for mud riding thats all not true. he is the one stating you can't make it in the places that a 4 wheel drive utv can go i say i can i do it all the time down here i don't do no rock climbing i mud ride he said them front tires don't pull thier weight THATS A LIE! if they didn't then when i would ride and the rear tires would spin and i stop moving forward then how come when i put it in 4x4 it starts moving again ??? how does it spins them big tires caked with mud??? that video of the xuv has stock tires on it so i don't think the mud is so slick of heavy otherwise it would be stuck just looks like water to me with a hard bottom. skip just seems to have a hang up on the 3 wheel thing. sometimes when i'm in the woods i have to unlock the rearend because it's to hard to turn i wouldn't want all 4 locked up that would be a nightmare. from now on i'll just ignore the 3 wheel drive coments being they don't mean nuthin .

 

[darkday]

Tommy they don't lock all the time only when there's slippage.

I always thought though that when one wheel slips all the torque goes to that one wheel?

I just don't know why this is still up for debate though. I'm not saying (and I don't think anyone is) that 3wd isn't good and will get you stuck instantly. But 4wd > 3wd. There's no question about that if you use simple logic.

4wd > 3wd > 2wd > 1wd. This would be a lot like me saying that 1wd is just as fine as 2wd in the snow. My car has an open diff and I drive through snow that is deeper then the ground clearance of my car. No problems. So what's the need of a locking rear? I don't see any need for it I mean if I can get through any snow I want to it seems a bit pointless doesn't it?

My logic falls a bit short wouldn't you say? Everyone knows if I had a locking rear of some sort I would be much better off and could get through even deeper stuff. Ice? Better pray to god you don't get a wheel on ice while the others are in snow. Can you believe I got stuck in 3 inches of snow the other day? I went off my driveway which was covered in ice but stopped with one wheel on it. Whoops so much for getting out of that one. Had to get the gator out, all because of 3 inches of snow...

/end rant.
