do you know the formula to figure out how much torque will be needed yo propel a veichle? |

Cole,
Formula is T=Fxr
T=torque in inch pounds.
F= drawbar pull.
r= wheel radius in inches.
Drawbar pull is in pounds per 1000lbs.of vehicle weight. If it is in mud which I assume it is, then this number would be 37 to 150lbs. I would take the worst case at 150lbs. This formula is also for level ground to keep a vehicle in steady motion. Hope this helps.

cris,
Dont buy a hydralic drive vehicle. test drive all the rest and make a choice, just that simple. also, look at the drive train, BEARINGS, and the quality of frame inside. doulble sealed bearings inside and out last alot longer than bushings. test ride the machines in the terrain they are designed for and not some cut rate car dealer lot were alot of these machines are sold and ride them for more than 5 minutes. make sure werever you buy one that they can service what they sell and have knowledge in the product. |

Why not an Hydralic Drive System? I only ask due to the Idea just hit me prier to finding the above, It seems to me the controls and power to the drives would be much better not to say anything of the direct power. I will be greatfull for any insight on this. i have yet seen one and thout what a quite way to go thru the woods?
Thank you for your time.
Clay. |

Hydraulics might be quiet but you still have to
have an engine to operate the pump or pumps and on the current design of a Hydraulic system you have to keep the RPM's up to get much speed out of an atv unless you just want to crawl through
the woods at say 1 or 2 mph all day. Look up a machine called HYDROTRAXX they are made here in
Indiana basically a good machine but a little more heavy and very loud ( constant reving )
to operate the pumps. |

Here is a link for the vehicle power calculation.

ClaySpence,
I noticed you had an interest in the Hydraulic rigs. You'll read about all of the bad things , such as noise. I drive a Hydro Traxx. I have owned about all of the most popular "chain Rigs", and have spent decades trying to keep the chains un-rusted and adjusted.My hydro is air cooled. Yep it is a little noisier than I like , but that does not prevent me from wearing hearing protection. The power,ability to turn 360,s,the instant "reverse" when I drop off into something I don't want to go in to, and the " hardly any maintenance", far out weights the little bit of noise. As far as speed, it travels along at 14 mph on hard ground or bog. It carries 4500 lbs and will float a 1000 lb. pay load.I can carry two moose and pull a trailer with another moose in it.The hydraulic wheel motors have not failed in almost 9 years and no hoses have come close to breaking. They are almost bullet proof and I haven't been able to break the thing as of yet.
They are a little more expensive than the argo 8 wheeler, but the hydraulic system is so much more advanced that the cost should never be considered as compared to the reliability.I always get a raise out of the argo-max owners and, once again, I'm not picking on them.Their rigs may very well fill their needs at less of a cost.I drive argos on my job here in Alaska, but I own a Hydro Traxx.
A rig gets your Butt from point A to point B.It just makes a difference how much time you want to spend driving or working on the rig.It,s kind of strange that I never see anything on this web about someone working on a Hydro Traxx, or needing some "chain links", or any other problem for that matter. It isn't that there isn't any Hydro Traxx,s out there, it is that they just don't BREAK often enough to warrant any questions.
I have also seen a lot of enteries on "how to build a hydraulic" rig.Kool!! Some are on the right traxx!!The "Chain Gang" always hate to see me talking about the hydraulic drive rigs.
Most of the time, I just drive and have fun and I am sorry that I don't have something to bawl about this old noisey, slow, dangerous,expensive,heavy, yet reliable Hydro Traxx.I get so lonesome sometimes.

YES, I AGREE WITH BUBBA, I OWN A HYDROSTATIC DRIVE
ATV AND HAVE BEEN VERY HAPPY WITH IT, IT COST A LITTLE MORE THAN THE ARGO BUT IT HAS NEVER BROKE DOWN OR NO MAINTENANCE OTHER THAN OIL AND FILTER
CHANGE IN MY 5 YEARS OF ENJOYING THE NATURE TRAILS. I LOOK AS MY FREE TIME IN THE FOREST AND SWAMPS AS VERY VALUABLE QUALITY TIME AND THE LAST
THING I NEED IS A CHAIN COMING OFF IN A BIG MUDHOLE ON A COLD MORNING. COME TO THINK OF IT THE
HYDROSTATIC DRIVE IS NOT NEW, THE FRONT END LOADER "BOBCAT" HAS BEEN BUILT LIKE THIS FOR 30 YEARS, THEY SELDOM HAVE A BREAKDOWN. AS FOR AS NOIS, THIS IS A MUFFLER ISSUE, MY ATV IS EQUIPPED
WITH AN EXTRA GLASS PACK MUFFLER AND IS NOT
CONSIDERED NOISY. |

I am intested in building a hydraulic system for a project of mine. Would any of you suggest any engine/pump combinations I should look at. It doesn't seem as if there are alot available. There was a coleman back a couple of years ago that idled down when there wasn't a load on the hydraulic system, I would like to figure out how they did that. Anyone have this kind of information? |

Well, if anyone here has ever driven a forklift, most of them use hydraulic motors, and just have pedal throttle like a car. WORKS FINE! All this talk of have to keep the pump idled up is nonsense. The only reason "bobcats" are set throttle machines is just so you can keep your hands on the sticks, and it won't bog when you lift a shit load of weight. I too have plans to build a hydrulic machine using one motor to run the chains on each side. Instant true 0 turn radius machine with immediate reverse, no having to shift it in reverse. Also light simple and efficient. I have also heard people say, "oohhh you would make it heavy and would have to put a much larger engine in to run the pump." This too is nonsense. The two motors weigh in at about 15lbs./each. A pump is about 25 and then all you need is an oil tank, valves and lines. But you get to remove the cumbersome trannys in most 6x6 that wight 70-80lbs. Horsepower wise, it is more a matter of making sure the pump has enough flow capacity or gallons per min., to run the two motors at top speed. Speed can also be adjusted by what sprockets you put on the motors to drive the chains. There will be little back pressure on the motors as the ones I was looking at have 300 plus foot pounds or torque each. Thats more than most v8 pickups generate. Think about it.... it'll work just fine! |
