Preventing tractor back flip

[bcp]

Here are lots of real tractors pulling from the drawbar. Most lose traction before the front wheels rise, but a few get the front end into the air.

DO they have internet access in the hereafter?

I think it depends on which place. It's one of those location, location, and location, thangs. Whichever it is, I doubt the provider actually gives you the speed for which they are charging you (for eternity).

I think a big factor is the torque being transmitted around the rear axle.

That all came about pretty fast..Hard to get in there and stop the engine, before it becomes a Grenade.Hence the kill-switch on a lot of race equipment.

Yes, it can flip over, even if pulling from drawbar lower than axle. I always thought that it could not until ~18 years ago when I was moving some dirt with a tow behind "tumble bug" (~6' wide bucket that tumbles to dump when rope is pulled). The bucket dug in really well, tractor front lifted quickly and I expect it would have went completely over if I had not had my hand on the clutch when it happened. It is scary to ride a tractor (1956 McCormick 650D, no ROPS, no seatbelt, hand clutch) and have the front lift very high. I expected damage but there was none.. (other than my stress level).

Well it appears the evidence is stacked up against me. It's gonna flip.

Thanks for the entertaining thread. It was good for our brains.

======================

This thread kept taking me back to when I moved on my property 38 years ago. I had salvaged a bunch of lumber by taking down old buildings and had it all dropped by a dump bed at the bottom of the hill. I had a 100 feet of 3/4" polypropylene line that I was choking bundles of lumber with. I tied it to the front bumper of my jeep and ran the line up and over my plywood roof. I made speed runs up the hill, dragging the bundles. There were some short 5 inch stumps along the way and one of the bundles rammed a stump and the choker slipped down the bundle and lassoed the stump. In a split second, the Jeep was up on the back bumper. I had gotten the clutch in just in time so that it didn't go over all the way. Man, it sure came down hard. I was happy it was on the wheels.

If he's a good sport, he'll share. :thumbsup:

Look at this video. At the start you can clearly see the hitch is well below the axle. Later in the video the front wheels are well off the ground. If the same thing happened at higher speed with bouncing wheels, erratic traction, unpredictable backlash, and other unexpected forces going every which way, then its easy to imagine it could flip all the way.

To me, it somewhat defies logic but see for yourself...
