3-Point Hitch Chain hookup on rear of my L3400: best attachment point?

[Baby Grand]

It's just about impossible to cause a side rollover when pulling from a fixed drawbar which is well below the tractor's COG. I say "just about impossible" because someone, somewhere has probably accomplished it using a combination of speed and carelessness.

I agree with this up to a point. As a general rule, though, it can get you into real trouble but fast. The concern I have with any side pull is that since the drawbar is well above the bottom edge of the rear tire on the side of the thing being pulled, the bottom edge of this tire can act as a fulcrum to the tractor with the pull line creating a tipping force. If this happens, and it's not unlikely in a side pull, stability can evaporate quickly if the applied load on the line gets very large. This tipping force can be greatly compounded if that tire spins and digs in, tipping the tractor, or is on the downhill side of a slope. It's sort of a secondary effect, but one you have to be mindful of so it doesn't bite you. Similar to center of boyancy vs. center of gravity on a ship.

It's for this reason that I strongly recommend a snatch block redirected side pull over a side pull directly coupled to the drawbar.

When one rear wheel comes off the ground, or nearly so, tractive forces effectively cease unless the differential lock is engaged. The tractor will stop long before it tips over when the load is hooked to the drawbar. The drawbar didn't end up in that place on the tractor by accident. Snatchblocks work well in theory, but more often than not a suitable anchor in the proper location isn't present. Snatchblocks also generally preclude the use of a chain for towing or pulling.

Side pulls are easily avoided in most instances by pointing the tractor in a different direction.

I have two ways to attach a chain to my tractor. Look at the drawbar and you will see the bent clevis (made that way) attached to it. Also, I can hook a chain directly to the hand-hitch that I made.

I have a 2'' trailer towing ball in my drawbar and simply place the slip hook of my logging chain around it.

I do the same thing with mine.

Hey Jim
I like the Banjo Links, where did you get them? I would feel safer with them in a lot of situations or when skidding multiple logs.

I picked it up at TSC here is the link Tractor Supply.

I guess I didn't look hard enough last time I was at TSC - I'll keep an eye out next time I'm there. Thanks

You have a good point and I hadn't considered the pull being self limited by the loss of traction. But lifting a rear is kind of cutting it close for me. And yes, moving the tractor to line up with the pull is a great idea.

I see that you have a chain hook on the top of your hand-made hitch; do you ever hook a chain to it for pulling?

I suppose that I am going to get into trouble with the safety police if I admit that I have, on occasion, used a raised wide drawbar (the long removable one that goes on the bottom of the three point) to get more traction. I know that this is not a recommended procedure but is not as much of an issue with a FEL installed. It was a little more of a problem with an old 8N that I used to drive but I have never raised the front of my L3400 with a FEL. But, if you ever do this the chain has to come straight out, not at an angle with the back of the tractor, and the chain has to go through a clevis to keep it in the middle of the drawbar so it can稚 move to the side.

Has anyone else ever done this and lived to tell about it?

On my L2900 I have the factory clevis drawbar,which basically is a "Z" shaped bar bolted to the drawbar at 1 end with a hole on the other end to run a pin between the bar and drawbsar
