Josh, you'll probably like this one: A 5.9L Cummings Diesel Ram 4X4 pulls out a big tree stump, though it takes several tries and adjustments. And this wasn't even the toughest dualie-rear version of the Ram.

Spelling it cummings is a good way to get crucified on a truck forum.


Dually vs SRW doesn't really affect torque. I guess the traction could make a difference, and sometimes the DRW axle might be geared lower(but not always).

mmarshall

True, but a dualie rear end can support more weight....and, of course, as you noted, you have the traction of up to six tires instead of just two or four.

Sulu

Dualie or not doesn't matter if you rear wheels are off the ground.

mmarshall

I'll agree. Got a point there.

He should be pulling in reverse to keep the rear wheel on the ground

LOL, it is, in fact, a "Cummins" diesel engine.

The only thing a DRW truck is good for is cargo capacity in the bed. How much load it can carry over the axle. Hence why they are used heavily in fleet applications for goosenect trailers, and 5th wheel campers belonging to us pensioners.

It makes no discernable difference in traction, it only helps with weight distrubtion under heavy load, and minimizing side sway in taller loads such as truck bed RV's.

To get the most trailer towing capacity from any truck, you need a Single Cab, Long Box, SRW diesel platform. So either the F350 (or 450), the Ram 3500 (or 4500), or the Chevy/GMC 3500. This combines the lightest truck with the most available power and most heavy-duty suspension package. The above described are the trucks they describe when Ford, GM and Chrysler say they can tow 35000 lbs. Base model, no frills, 4x2 diesel, single cab, single rear wheel pickups, with the highest numerical gear ratio they can fit in the pumpkin, usually a 4.10 or higher.

NO. Thats a fantastic way to blow your transmission. He should be pulling with the rope lower to the ground (as close to level with the rear end as you can get) and in a numerically lower gear ratio. There is a happy medium. The closer the chain gets to the base of the tree, the harder it will be to pull it out of the ground, but the higher the chain is placed, the more likely he will lose traction. Honestly this was too large of a task to attempt, even with this truck. with his lift and extra large tires, his torque has diminished considerably. in stock form, that truck would have yanked that right out. Looks are deceiving. Lifted trucks look tough, but often times their modifications diminish their usefulness as hard working machines. with 800ft-lbs of tq, he should have been able to pull that tree out with no issue, but his suspension was loading and unloading and his truck was bouncing.

The preferred technique to do this is with a stock pickup, yank, reverse, yank, reverse, yank, reverse.

Would added weight in the bed helped? Say 1000 lbs of sand bags?

Aron9000

Wrong tool for the job, but he got it done. Stump would've been gone with a medium sized tractor in one pull.

ArmyofOne

It would have, yes. The added strain on the driveline from the extra weight is marginal compared to the burning of transmission bands from 4-wheel wheelspin on dry pavement and the crunching of gears in the rear axle due to wheel hop. It would have also pre-loaded the suspension, eliminiating the vast majority of "bounce".

When I posted this thread, Josh, I did not mean to imply, by any means, that it was a wise thing to do with that truck, or that there would be no (possible) damage from the way it was done. It does show, though, what kind of torque that Cummins diesel and drivetrain is capable of, though, even if abused or mishandled.
