At my local county pull there were several classes both gas and diesel. I dont think anyone was running close to the HP that most guys run here but no one came close to a full pull. Then for EDIT and giggles this guy pulls up in a uni mog hooks up and pulls the sled right out of the arena at like 3mph...never so much as spun a tire! What was the giagantic advantage the mog had over the other vehicles?

 

Portal axles, super low gearing. Those things are very tough.

 

I dont understand how I couldnt just creep down the track in low range 1st gear and just keep going...the thing never ran outta traction. I know it doesnt have a heck of alot of power...

 

its the super low gear ratio. I have worked on some with 658:1 ratios in low range. those things will pull, climb, descend, or push over anything that you can put in their way.

Planetary wheel end assemblies, torque multiplication like you have never seen. I have seen many of these units used in some truly ugly situations, and as mentioned above, they just don't stop.

If you can afford the purchase price, they are probably the best all around utility vehicle that you can get. There is a fellow here that uses his to pull a schulte brushcutter, all kinds of off-angle approaches and departures, lots of sidehilling, and it goes, and goes, and goes.

 

Weight, hitch hieght...

 

Just lots of TORQUE with reeeeallly low gearin!

 

His gears are WAY lower than you would be in first low. Top speed of some of em is under 60.

 

That MOG prolly weighs 3 times what our trucks do and it has gears lower than my farm tractor!!

 

speaking of cool european heavy trucks...

If you do a google video search on tatra truck trials you get all sorts of belching black smoke and turbo's whistling....

 

I have a buddy that has a set of 404's in his rock buggy, they have a final drive of 7.56:1 and with a 42" tire at 3 psi have 23" of clearance at the center of the diff. The only weakness they have is snapping the portal box off if you hit it just right.

they actually have good size diesels in them to (well some do)

 

Mostly they are very small displacement 4 cyl Merc. diesels. nothing over 100hp

 

Strange. There was also a Unimog at our local pulls this year. Only this guy didn't do so well. I figure he went about 175 feet and my near stock truck went 208. Wrong gear choice, inexperience, I don't know. On a side note, I weighed in right after him and asked the staff what it weighed. They told me 15,900 lbs

 

actually no the newer ones run a, Mercedes-Benz MBE900, 6 cylinder, 260 hp

 

Your right, I apologize, I was refering to the 404s, 406s, and 416s that everyone does the axle swaps out of.
