@DavidBarkey i wouldn’t want my foot anywhere near it!
I realize we all have quite a bit of experience with our tractors, but I thought if someone new to them was reading this maybe I should elaborate on what I mean about too much traction.
If you look at these pictures I think we have all seen this at a tractor pull.
These guys are actually transferring the weight of the tractor to the rear to give more traction to pull the sled. Most of the time tractor pull rules will require wheelie bars on the back to keep the tractor from flipping over, especially on modified tractors. If you get into this situation at home while using your tractor it can flip all the way over and crush you very quickly, before you can stop it. That’s why I say I’d rather have some wheel slip.
The guy on that Farmall is really risking breaking the front wheels off when he comes back down. Ask me how I know that can happen!
Anyway probably not necessary, but I figured I’d add it.

It’s, 3/4’s of a second for that Farmalls front wheels to leave the ground, and then the tractor to be completely upside down. You’ve got no chance to catch it from going over. I know of a few people here where I live that we’re killed because of the tractor flipping over on them.

Maybe fab up some of these wheels? What could go wrong? I see some are removable on the type Noel was speaking of.
Now somewhere on the net I remember a topic on a forum where the guy had built an external diff lock. Think of it as follows. Disc brake rotor installed but machined teeth on outer edge. On the back lower rear axle area was some pillow blocks with a driveshaft with gears on the ends and a disconnect on the shaft. I'll look for it. Seemed like it would work?

In the end if trying to achieve traction without repercussion I would install dual brakes. It's on my list of things I wish I had time to do.

Thanks for waking up an old memory from long ago
At one tractor pull they were half way through a weight class. Next tractor up, a grampa came out with a JD B. The crowd started roaring and laughing. The old boy started pulling, you could here the engine start to lug after a bit and the tires started to wrinkle. More luging and wrinkles getting bigger, the front end started getting lighter till the wheels were off the ground and bobbing up and own with each pop of the exhaust. Pretty soon the draw bar was on the ground and still pulling, The engine was turning so slow I could hear and count each pop from the exhaust. When he finally spun out he must have hit the clutch and breaks at the same time because the rears stopped turning and the front stayed in the air for a while then slowly came down. He got a standing ovation because he had pulled 100 feet farther than anyone else had up to that point.

Pictures of the hydraulic operated steel wheels I mention earlier.

@propane1 That is quite the setup . It would take a healthy bite of the ground .

A similar John Deere pulling story like Gordys, from years ago. A fella I know had a JD B or A, can’t remember the model, but any way it was a gas 2 cylinder tractor. He had it at the pulls. Rear tires were basically bald in the centre. He started pulling, and kept going and going. Just when you thought it was gunna stop, it just kept going. So the weight got to the front of the drag and the tractor kept going, the fella sitting at the back operating the drag, decided to get up and he got up to the front of the drag to put more weight up there to stop the tractor. Tractor just kept going, barely running, it passed the full pull mark and kept going till he ran out of track. Quite a thing to see. Crowd was going crazy.

Good memories @Gordy , @propane1 ! As much as I can do with out the green and yellow, I have to admit those old A and B models had some good lugging power. Growing up with Farmall and AC 4 cylinder engines those 2 cylinder JD’s always sounded like they had a miss to me!
I used to pull my M and Super H, just farm stock class.
In one weight class it was always just me and 1 guy on an old JD. I’d win one then he’d win one! Just like you guys said you’d think he was done and that stupid 2 cylinder would pop a couple more time and edge me out!
I was just having fun but he got pretty serious into pulling and ended up getting disqualified from farm stock, I forget what he did to the tractor, but since it was just me and him In that weight class, I asked the judges to let us pull anyway. I never could beat him after that!
